The Valdivia Earthquake
Earthquakes, also referred to as temblors, are one of the world's most powerful occurrences. The Earth has four layers: the crust, mantle, inner and
outer core. Earthquakes occur in the crust and upper mantle (Refer to Figure 1). The mantle is made up of semi–molten rock called magma. The upper
mantle rock is hard. The crust is the outer layer of the earth. Together, the crust and upper mantle make up thelithosphere. The lithosphere is 20–50 km
thick and is cracked. The asthenosphere sits below the lithosphere. The lithosphere consists of tectonic plates (lithospheric plates). Tectonic plates is the
theory that the Earth's outer shell is divided by slabs of solid rock. When these two tectonic plates make frictional contact the outcome may be deadly.
Sometimes there can be smaller shocks that occur, one's before called the foreshock, and one's after called the aftershock and the main earthquake called
the main shock.

Megathrust earthquakes are the most powerful earthquakes in the world and can produce tsunamis through a variety of structures. The Valdivia
earthquake, in theory, is a convergent the earthquake was caused by the Nazca plate releasing tension and descending underneath the South American
Plate.The Great Alaska earthquake also appears to be a convergent boundary earthquake as the Pacific Plate lurched underneath the North American

Seismic waves are waves of energy that travel through the Earth's layers as a result of earthquakes. During an earthquake, the waves released may be
"P" or "S" depending on the way and speed of the wave (Refer to Figure 3 and 4). P–waves, or primary waves are longitudinal waves. Their vibrations
are along the same direction as the direction of travel. P–waves are faster than S–waves. S–waves, or secondary waves are transverse waves. They

Knowledge is the skill acquired by a person to have facts or information through education or experience. To wonder is to be curious to know something.
The meaning behind Morgan's quote is that once someone learns something new, they want to investigate or know more.
Once we are told something we did not know, our curiosity tells us to do some research or to ask questions in order to know more about the topic. I
have been in this situation multiple times. When I was first told about the Northridge Earthquake that happened a few years ago, I was shocked and I

Wind, Earthquake And Its Effect On The Earthquake Essay
Unlike wind, earthquake is a different phenomenon which generates a ground motion. The intensity or acceleration of the earthquake depends upon
the magnitude and location of its epicenter. The seismic waves caused by the earthquake cause inertial forces in the building. The inertial forces are
created when an outside force tries to move a body in rest which happens in this case as seismic waves tries the move the building in rest. We all know
that when a building is subjected to inertial forces it should obey the newton's second law of motion.
F=M.a –––––––––––––––––––– (3)
Where 'F' is inertial force and 'M' denotes mass of building and 'a' is the acceleration with which the building is moved due to seismic activity.
Duration, velocity and displacement:
From the newton's second law, it is evident that acceleration is a key factor in determining the forces on a building. But there is one more criteria that
we have to look into is the duration of the earthquake. Earthquake that has moderate acceleration, sustained over time, can cause much more damage to
buildings than a single much larger peak. It weakens the building structure and reduces its durability. The strong–motion duration is often termed as
"bracketed duration" (Arnold 2013). This is the shaking duration above a certain threshold acceleration value, which is 0.05g, and is defined as the
time between the first and last peaks of motion that exceeds this threshold value (Arnold 2013). The strong motion

Earthquake : The Seddon Earthquake
In Seddon the aftershocks were a lot fewer but there were still 1,700 and only 45 being over magnitude 4. (see image 2). From the earthquake features
discussed, we can see that despite the Seddon earthquake having a greater magnitude and similar type of fault movement, it was the fact that the
Christchurch earthquake carried a lot more power and force with its initial ground movement and shaking, and its continual aftershocks, that the effects
of this earthquake were much worse than the Seddon earthquake.
In Christchurch, after the earthquake, more than half of the buildings in the central business district, around 10,000, had to be demolished, with a
total of 100,000 homes damaged. Many heritage buildings were also badly damaged and some had to be demolished, with the most recognisable the
Christchurch Cathedral. This damage in Christchurch was especially bad due to the effect of seismic lensing. Seismic lensing is caused during an
earthquake when the p, s and I waves produced by the earthquake bounce of their surroundings. If these surroundings have hard surfaces the waves

The Great Chilean Earthquake : An Earthquake
The Great Chilean Earthquake An earthquake is the shaking of the earth by seismic waves radiating away from the disturbance, most commonly fault
movement. The great Chilean earthquakes origin was of the coast of Chile at a subduction zone, referred to as a hot spot for seismic activity. A
subduction zone is a region on the crust of the earth where two tectonics plate meet one another. The area where the two plates meet is called a plate
boundary. When two plates meet at a subduction zone, they converge towards each other, and one these tectonic plates come into contact with each
other, one bends and slides underneath another, resulting in one curving down to the mantle. In this circumstance when subduction is taking place the
denser plate is the one that sinks beneath the other. On the earth's surface there are two main types of crust; the oceanic and the continental. The
continental isn't as dense as the oceanic making it slide above while the oceanic subducts down, in a convection motion to recycle itself then be
remade when it pushes itself up. The place the denser medium goes towards is the mantle that consists of molten rock and it accounts to 84% of earths
volume. Subduction only takes effect when two plates of different density collide, for if two continental crusts converge and push together neither will
subduct, so it will be like a car crash where the two mediums smash into each other but neither subducts, as an example of this event look to the

1906 San Francisco Earthquake An earthquake is the vibration of the Earth produced by the rapid release of energy. Most earthquakes occur at a plate
boundary, usually along the Circum–Pacific belt. They tend to be caused by the slippage along large fracture in the Earth's crust, such as a fault for
example. However, they can also occur from a volcanic eruption, or an atomic explosion. There are two different types of shocks to a major earthquake;
there is a foreshock and an aftershock. The foreshock concedes of smaller earthquakes that precede a major one by some time period, and an
aftershock that concedes of small earthquakes due to the adjustment of the crust after the major earthquake. Earthquakes affect numerous things, from
soil liquefaction to construction, and the rupture of power, gas, and water lines. There are two ways to measuring the size of an earthquake, those are
intensity and magnitude. The intensity is a measure of the degree of an earthquake shaking at a given locale based on the amount of damage,
measured through the Modified Mercalli Intensity Scale which bases of the surveys of those whom were affected, and ranges from 1 to a 12. The
magnitude is the total amount of energy released at the source of an earthquake, which tends to be measured on the Richter magnitude scale. This
method is based on the amplitude of the largest seismic wave, and ranges from a –2 to infinity. Unfortunately there

The Sichuan Earthquake also known as Wenchuan Earthquake occurred on May 12th, 2008. The horrific earthquake was located in the mountainous
dominant region of Sichuan, south–western China. The earthquake was measured to have a magnitude of 8.0 by the Chinese. The quake affected
four–fifths of the buildings located in the area. Towns, villages and schools had collapsed and had been destroyed. Close to 90,000 people were
tallied as missing or dead. The Chinese Government report stated that more than 5,300 Children (mainly students at school) were killed by the quake.
As well as 375,000 people injured from collapsing buildings and tumbling debris. The Chinese government sent relief workers and 130,000 soldiers to
the devastated location. Yet remote villages were hard to reach due to the insignificant amount of usable rescue equipment needed to clear the damage
(Pletcher, n.d.). 4,800,000 people (BBC, 2013) were left homeless due to the earthquake.
The prediction of earthquakes cannot be tallied as a certain thing at the present time, however educated estimations can be used to develop and warn
people of possible earthquakes. Predictions can and are based on a few factors. One includes new cracks in rocks, this occurs due to a great build–up of

On Earthquakes
An earthquake is a shaking or trembling of the crust of the earth caused by underground volcanic action or by the breaking and shifting of rock
beneath the surface. The volcanic action and shifting rocks create strain which continues to build to a sudden release of pressure resulting in a shock
wave. The vibrations produced in the crust can vary from barely noticeable to enormously destructive. Shock waves can be classified into two broad
categories. Waves that send particles oscillating back and forth in the same direction as the waves are traveling are called primary. Primary waves,
sometimes called compressional waves, travel through the earth beneath the crust. Secondary ... Show more content on Helpwriting.net ...
The modern seismograph was invented early this century by a Russian seismologist, Prince Boris Golitzyn. This device made possible the modern era of
earthquake research.
Although earthquakes have occurred and affected mankind for as long as humans have been around, historical records are either lacking or
considered unreliable before the middle of the 18th century. However, some records do exist and date major earthquake events back to 425 BC when
one occurred off the coast of Greece resulting in an island named Euboea. Another occurred in Asia Minor about AD 17 and another leveled much of
the Roman city of Pompeii in AD 63. During the Middle Ages, severe earthquakes struck England, in 1318; Naples, Italy, in 1456; and Lisbon,
Portugal, in 1531.
Casualties from major earthquakes have resulted in the greatest disasters in history. The worst occurred in 1556 in the Shannxi (Shensi) Province in
China and killed an estimated 800,000 people. During the 18th century, the Japanese city of Edo (site of modern day Tokyo) was struck and killed
200,000. Earthquakes in Sicily in 1693 and Lisbon in 1755 each killed about 60,000 people. In 1797, approximately 40,000 died when Quito, Ecuador

How Does Earthquake Affect The Earthquake
Task Two: Earthquakes and Buildings
The type of buildings that were the most damaged in the 2011 Christchurch earthquake.
In the 6.3 magnitude Christchurch earthquake that occurred at 12.51pm on the 22nd of February 2011, the types of buildings that were the most
damaged were houses and commercial buildings that were built in the 19th and early 20th century. The majority of these buildings that were damaged
were ones that relied on single or double brick for their structure. This relates to how the bricks are placed on the house and whether there are two
layers or one layer of brick. Buildings made of bricks and stones were damaged because they can't move with the earth and most of the bricks crack
and fall off making the structure a lot less stable and more likely to collapse in an aftershock.
Brick chimneys on the old wooden houses fell over and crashed through the roofs and caused a lot of damage. Stone buildings such as the Old Stone
House were also badly damaged and had to be closed following the February 2011 earthquake. The most structural damage mainly occurred in houses
that were made of heavy materials such as stones, bricks or concrete. This is because it is harder for these building materials to withstand strong
shaking and to support their own weight when they begin to lose shape. They can't bounce back as easy once they have been forced in the other
direction. This forces the buildings to fall outwards or collapse.

Earthquakes: A Natural Hazard
Introduction to Earthquakes
An earthquake is a natural hazard that causes death and destruction. Earthquakes mainly occur on the boundary of two tectonic plates, known as fault
lines, as the plates move against each other and get stuck which creates a strain and results in rocks breaking. This releases energy into the lithosphere
(crust and upper mantle) causing shaking of the earth's surface. The energy released is called seismic waves and these are measured on a logarithmic
scale called the Richter scale.

systems can be affected so most will set up plans for contacting friends and family.
Immediately after an earthquake looting often happens as many will be without supplies however some people react very differently and try to help
as many people as they can. Countries around the world will send money and food; some may even send volunteers to help and administer first aid.
The rubble will be cleared to free the people trapped. Buildings being made safe is another way they would help but depending on the country's
funding it doesn't always happen immediately. Tourism may decrease as the tourists could be scared of another earthquake or aftershock occurring.
Long–term responses would be things like building restoration because aftershocks are not unusual. Before or after restoration begins an investigation
may be required to figure out why the building collapsed and if there were any faults in construction. The economy will be negatively affected as
rebuilding is costly and normal work is prevented from happening for quite a while. Whilst there are investments made for rebuilding and aid is sent in
the immediate aftermath, families may struggle with reduced incomes and replacement of clothing and household items.

Plate tectonic activity is related to many other things like, volcanoes and earthquakes. These natural hazards can be found in linear belts around the
globe. There are seven large plates and many small ones, the main types of plates include the divergent plate boundary (pulls away), convergent plate
boundary (move towards each other) and transform plate boundary (slide past). Ocean–continent boundaries create earthquakes up 700 km deep and
forms seafloor trenches, it leads to andesitic volcanoes in mountain ranges. Yellowstone is a 'hot spot' this is where heating and igneous activity occurs
within crust. Although, not all plates move at the same rate, they are relative to each other. Continent– continent boundaries with divergent can form
rift valleys, earthquakes less than 100 km deep, and basaltic/rhyolitic volcanoes. At Convergent they have young mountain range, 300 km deep
earthquakes, and no volcanoes. At transform, they have a fault zone, less than 100 km deep earthquakes and again no volcanoes. With ocean–ocean
boundaries there is oceanic ridges with rift valley, less than 100 km earthquakes, and basaltic pillow lavas at divergent. On convergent there are
seafloor trenches, 700 km earthquakes and andesitic volcanoes in island arc. With transform you have ridges and valleys in oceanic crust, less than 100
km earthquakes, and some basalt. Plates are driven by the convection in the mantle and movement of the lithosphere.

– Large amounts of people being at risk
– Lots of large structures such as buildings
– Set off landslides
– Tsunamis
The devastation of the Earthquake can differ depending on the location and environment of the country the Earthquake occurs. Countries that have
fault lines close to the ocean are more at risk of having large Tsunamis. These waves can reach speeds of up to 500 kilometres per hour and cause
massive devastation to anything in their path (ABC 2017). Some places such as New Zealand are more likely to have things such as landslides since
the country has large amounts of hills and countryside.

The Disaster Of A Earthquake
The year 2010 was an active year for earthquakes and other natural disasters, racking up a total of four earthquakes ranked 7.0 or higher. Two of
these quakes were merely a month apart, and started the year in a very destructive way. The first was a 7.0 in Haiti, the second over 3,000 miles away
in Chile, an 8.8. Though both ravaged their countries, one was decidedly more devastating than the other. Looking at the magnitudes of the quakes, you
might think Chile received the worst of it, but after further inspection, you may not be so sure. While the magnitude of a quake can be a big factor in
the corresponding effects, the infrastructure of the affected area plays an even larger role in the number of casualties and the amount of devastation
that is experienced. This devastation is further increased in coastal areas due to the high likelihood of tsunamis shadowing high magnitude quakes.

Earthquakes Disasters Caused By Earthquakes
Earthquakes are an unfortunate consequence of, well, living on earth. While other hazards such as volcanos, tornados, floods, and wild fires all have
clear visual indications that allow for us humans to get away from them, earthquakes are much more insidious than the aforementioned disasters
because they have no such indicator and the damage they inflict is near instantaneous. Luckily for us humans, seismologists have spent a good portion
of the 20th century finding out why earthquakes occur, how to predict earthquakes that have not happened yet, and how to minimize damages caused

Earthquakes are a marvel of geology. When faults under the surface of the earth move, the ground moves. These earthquakes can be very mild, barely
registering or they can be horrific with far–reaching consequences. Scientists have become fascinated with the study of earthquakes for centuries but it
is only in recent years that quantified data has been collected and analyzed by scientists regarding these geologic phenomena. Before the invention of
the Richter scale, less accurate means of measuring an earthquake's intensity were used by geological scientists.
Until the early 1900s, earthquakes could only be measured after the earthquake had ended and then only approximations could be made. The first
attempt at scientifically measuring an earthquake's intensity was performed in the middle of the nineteenth century. In Italy in 1857, the after effects
of an earthquake were quantified (Lutgen 2011, page 179). A map was created to show the comparable damages that were found in different areas. This
allowed geographers to make maps which would show the areas of highest intensity and how intensity lessened in surrounding areas. Although this was
helpful, it only showed comparative intensities, not quantified data.

Predicting Earthquakes by Gregory Vogt, the Greeks, "blamed the earthquakes on Poseidon, god of the sea"(25). The Hindu believed that "the earth
was a platform that rested on the back of eight great elephants. When one of the elephants grew weary, it lowered and shook its head causing the
ground above to tremble"(Vogt 25). Margaret Poynter writes "many primitive people thought that the earth rested upon the back of some... Show more

He made tests, drew a world map, and recreated earthquakes only to find that rocks are being overstressed at the faults. "A fault is the place where
two plates meet and are rubbed against each other" (Groiler Electronic Publishing,
Inc.). The book, Predicting Earthquakes, the author points out "There are generally three kinds of faults: normal, reverse, and strike–slip. By careful
observation and measurement, geologists, acting like detectives, can tell how much a fault moved, which part went up, which part went down, and
which way the fault moved" (Vogt 26). "When one of the plates slip under the great amount of stress at the fault, anearthquake occurs. The shaking we
feel are the passing of long waves" (Putnam 443). "The L–waves (long waves) travel at slower velocities that the primary and secondary waves. These
waves make the largest squiggles on a seismograph but their effect diminishes rapidly with distance. The L–waves are limited to the crust" (Putnam
443).
One of the two kinds of waves are "Primary waves are a kin to sound waves, and thus produce alternate compression and rarefaction in the medium
through which they travel much like the waves that spread out through the air in all directions from a tuning fork" (Putnam 444).
The second of the two kinds of waves are "Secondary waves, the particles in the rock through which the wave is traveling vibrate at right angles, or
transversely, to the direction of

Essay On Earthquake
The data from nine earthquakes happened in winter and summer time, with magnitudes ranging from M 3.0 to M5.7, was collected at a sampling rate
200 Hz and preprocessed for the further analysis [4]. Then, dynamic properties of the structure were obtained using modal property identification
toolbox (MPIT 2.0) developed at the University of Auckland [13]. The modes were determined from the following system identification algorithms:
–Frequency domain methods: the peak picking (PP), the frequency domain decomposition (FDD), the enhanced frequency domain decomposition
(EFDD) –Time domain method: stochastic subspace identification (SSI) method [14] identifying the stable poles by generating singular values around
them from the singular value... Show more content on Helpwriting.net ...
Then, the most plausible modes was chosen by comparison of MAC values of each date for each SI algorithm. Since fundamental mode of the
bridges always excited by the translational ground motions during earthquakes, transverse components of mode shapes only were described in this
research to estimate the input of different bridge components on the bridge dynamic response. The frequency values obtained by each method,
except of SSI for summer dataset, at each season and their mean and coefficient of correlation are shown in Table 3.1 and Table 3.2. From this
figure, the values of fundamental transverse frequency identified by each method are highly correlated for all methods, the mean coefficient of
variation was no more than 0.02. In addition, no relationship between the transverse frequency and the depth of frozen soil at specific dates was
observed. A high correlation between mode shapes, with MAC value 0.95 or higher, was observed for two frequency domain methods only, FDD and
EFDD. Therefore, the average values of natural transverse frequency calculated from the values identified by each method, 7.69 Hz and 2.85 Hz, and
mode shapes obtained by FDD technique (Figure 3.1) were chosen as a baseline experimental values for the further calibration of the numerical models
developed for winter and summer respectively. The bridge transverse response is mainly symmetrical; the possible

Earthquakes: The Same Effects, but Different Responses
Earthquakes occur as a result of the abrupt release of energy in the Earth's crust that creates a series of waves known as seismic waves. Earth quakes
greatly affect people whether they are living in economically disadvantaged countries or in economically developed countries. However, the way each
of them responds to the hazard is different.
The tectonic movements in the earth's crust are the initial causes of earthquakes. These movements bring about forces of tension and pressure, these
forces stress up the earth's crust. As the stresses increase, an imbalance in equilibrium of the rocks which results into breaking of rocks and
displaced. The energy accumulated during the process is released giving raise to waves. The waves cause vibration of objects they come across with
causing a lot of impact on them. This may include shaking and rapture of the ground. As a result there is damage of infrastructure, landslides, fires due
to damage caused to electric and gas lines.
Volcanic eruptions can also cause earthquakes since they are often very violent and can cause vibrations to the earth's crust, this can result into rupture
of geological faults. This is as a result of the movement of lava beneath ... Show more content on Helpwriting.net ...

A Brief Note On The Earthquake Of Earthquake
Abstract
Earthquake engineering is a subject where a person can be overwhelmed with information but still crave for knowledge due to its unpredictable
nature. Earthquakes are a natural repetitive occurrence on planet earth, which due to its devastating impact, have caused a lot of damage to
structures and caused loss of life. Therefore engineers, scientists and geologists were required to take action and one of the many first steps was to
identify the regions of seismic activity. The argument in this essay is not how to prevent earthquakes as that is out of the control of humans but how
to minimise the damage and deaths caused by them by designing better buildings. The challenge to first achieve this goal was by engineers in
America, where in 1906, in the state of California, due to the frequent earthquakes in the state, building design codes and safety standards were
established. These design or seismic codes have helped to reduce the damages caused by earthquakes. Therefore the solution for people in active
seismic zones is to adhere to the seismic codes strictly, designed by engineers in order to help strengthen buildings and reduce the loss of life when an
earthquake occurs.
The greatest number of earthquakes occurs in Asia, America, Caribbean Islands and Europe but according to Hyndman, D and Hyndman, D (2012),
earthquakes do not actually cause the death of people but the falling debris and buildings do. This is why it is important for engineers to use

It's recognized as the second deadliest earthquake in New Zealand following the 7.8 Hawkes bay Earthquake (Kaiser et al, 2012). The earthquake
was first thought to be an aftershock of the 7.1 Darfield earthquake of September 2010 at the eastern edge. This was an area that originally was of a
low earthquake occurrence rate since prior to 2011 there was no knowledge of a fault's existence thus catching the New Zealand citizens off–guard. The
Christchurch earthquake resulted in 185 casualties affecting more than 300,000 people (Kaiser et al, 2012). The earthquake first made contact with in

story in our modern day world, but this was no natural phenomom to the people of ancient Greece. In Homer's great poem The Odyssey many of
these natural phenomenons were created by the powerful Greek Gods, while in the modern day article Are earthquakes on a rise? Is California's

Some of most notable events that manifest these major differences of thinking between these two periods of time consist of the acts of poseidon
being the cause of treacherous weather conditions at sea resulting in the setback of his return home, Zeus washing Odysseus boat up to shore and the
bag of wind given to Odysseus by the God Aeolia as a one way ticket back home.
Poseidon created a major setback of harsh weather conditions for Odysseus and his crew out of anger and vengeance for his son Polyphemus after
Odysseus shot an arrow in his eye leaving him blind. As the God of Sea, it is believed that Poseidon has the power to create unimaginable storms
and in this case a storm so strong its outcome delayed Odysseus voyage home by years, but modern day science proves otherwise. " Hear me,
Poseidon who circle the earth, dark haired ... let him come late, in a bad case, with the loss of all his companions, in someone else's ship, and find
troubles in his household " (Homer 9) Polyphemus knew that his anger towards Odysseus actions could quickly be resolved by the assistance of his
father's powers. This shows to prove that the ancient grecian people's religious culture is greatly based on the doings of the Gods, and has greatly
impacted their way of thinking. The possibilities of other causes was very

Most of the people succumbed to diseases that arose from the sanitation, infections, and other health related issues that occurred after the disaster. This
is because they lacked their own mechanisms of combating infections, sanitation issues, and post disaster mental issues (Huus, 2010). They also lacked
response plans for a disaster of a higher magnitude. For example, there was no disaster management system that showed the various protocols of
managing a large–scale disaster. Therefore, health issues such as sanitation, comfort, and management of communicable diseases was a major problem
(Farmer et al 2011). Other factors responsible for this problem is the high level of poverty, lack of infrastructure, and the large population. In Chile,
there were established mechanisms of managing the disaster. There were health interventions that were available, including rescue teams, preventive
techniques, sanitation and other disease management protocol. For example, organisations such as AmeriCares delivered about $730,000 in medical

Frog appears and explains that the fight took place in his imagination which brings up magical realism again and questions reality. The fact that
Frog is exhausted and wounded shows the reality of the event through the circumstance of the frog explaining that Katagiri did help by leading the
way with a foot powered generator. Frog explains that he is unable to defeat the worm but held it off in a draw enough to prevent the earthquake.
This reality is quickly questions by the fact that frog tells him that the battle took place in the area of imagination. This magical realism is
exemplified at the end when Frog slips into a coma and the disturbing image of boils popping and maggots and worms crawling out of the body. The
insects fill the hospital room and Katagiri screams, but when the nurse turns on the light, the insects and frog are suddenly gone. Katagiri is delirious
but he believes that frog sacrificed himself to save Tokyo from the earthquake. Alex Bates might use this sacrifice as evidence for his claim, but I
would argue that, again, the frog's representation at the end while he is disintegrated into insects, shows the rejuvenation and transformation of
Katagiri. Katagiri is able to rest easy after this happens as he is satisfied to have participated in such a glorious battle after having spent his life being

The Valdivia Earthquake: One of the Most Powerful in History

  • 1. The Valdivia Earthquake Earthquakes, also referred to as temblors, are one of the world's most powerful occurrences. The Earth has four layers: the crust, mantle, inner and outer core. Earthquakes occur in the crust and upper mantle (Refer to Figure 1). The mantle is made up of semi–molten rock called magma. The upper mantle rock is hard. The crust is the outer layer of the earth. Together, the crust and upper mantle make up thelithosphere. The lithosphere is 20–50 km thick and is cracked. The asthenosphere sits below the lithosphere. The lithosphere consists of tectonic plates (lithospheric plates). Tectonic plates is the theory that the Earth's outer shell is divided by slabs of solid rock. When these two tectonic plates make frictional contact the outcome may be deadly. Sometimes there can be smaller shocks that occur, one's before called the foreshock, and one's after called the aftershock and the main earthquake called the main shock. The richter scale, developed ... Show more content on Helpwriting.net ... Megathrust earthquakes are the most powerful earthquakes in the world and can produce tsunamis through a variety of structures. The Valdivia earthquake, in theory, is a convergent the earthquake was caused by the Nazca plate releasing tension and descending underneath the South American Plate.The Great Alaska earthquake also appears to be a convergent boundary earthquake as the Pacific Plate lurched underneath the North American Plate causing the earthquake. Seismic waves are waves of energy that travel through the Earth's layers as a result of earthquakes. During an earthquake, the waves released may be "P" or "S" depending on the way and speed of the wave (Refer to Figure 3 and 4). P–waves, or primary waves are longitudinal waves. Their vibrations are along the same direction as the direction of travel. P–waves are faster than S–waves. S–waves, or secondary waves are transverse waves. They travel at right angles to the direction of ... Get more on HelpWriting.net ...
  • 2. The Northridge Earthquake Knowledge is the skill acquired by a person to have facts or information through education or experience. To wonder is to be curious to know something. The meaning behind Morgan's quote is that once someone learns something new, they want to investigate or know more. Once we are told something we did not know, our curiosity tells us to do some research or to ask questions in order to know more about the topic. I have been in this situation multiple times. When I was first told about the Northridge Earthquake that happened a few years ago, I was shocked and I was dying to know more. I had to do some research on my own and my knowledge about the earthquake expanded. Not only did I know what happened, but I also knew how it happened, why it ... Get more on HelpWriting.net ...
  • 3. The Vancouver Earthquake destruction, as a result of movements within the earth's crust of volcanic action. Well no parts of the surface of the earth are protected from earthquakes, but some parts of the world experience earthquakes more frequently than others do. You will find that earthquakes are usually most common at tectonic plate boundaries where different plates meet. The largest events usually happen where two plates are colliding or colliding and sliding past one another, particular around the edge of the pacific plate. Large shallow earthquakes also happen where two plates are pulling apart with the creation of new oceanic crust along mid–ocean ridges and on the transform faults that intersect them. Shallow intraplate earthquakes occur in the relatively stable interior of continents away from... Show more content on Helpwriting.net ... The time of this disaster was from the 22 of February 2011 at 12:51pm. The earthquake hit the Canterbury region in New Zealand's south island and was centered 2 km west of the port town of Lyttelton, and 10km south east of the center of Christchurch, at the time ne Zealand's second most populous city. The damages to Christchurch where shocking as there were road and bridge damage and hampered rescue efforts. Soil liquefaction and surface flooding also occurred. Road surfaces were forced up by liquefaction, and water and sand were spewing out of cracks. A number of cars were crushed by falling debris. In the central city, falling buildings crushed two buses. Because the earthquake hit during the lunch hour, collapsed buildings buried some people on the footpaths. Damage also occurred to many older buildings and on the 28th of February 2001 the prime minster at the time announced that there would be an inquiry into the collapse of buildings that had been signed off as sale after the 4 September 2010 earthquake, This earthquake killed an amount of 180 people which is shown on page 2 and this is ...

  • 4. Wind, Earthquake And Its Effect On The Earthquake Essay Unlike wind, earthquake is a different phenomenon which generates a ground motion. The intensity or acceleration of the earthquake depends upon the magnitude and location of its epicenter. The seismic waves caused by the earthquake cause inertial forces in the building. The inertial forces are created when an outside force tries to move a body in rest which happens in this case as seismic waves tries the move the building in rest. We all know that when a building is subjected to inertial forces it should obey the newton's second law of motion. F=M.a –––––––––––––––––––– (3) Where 'F' is inertial force and 'M' denotes mass of building and 'a' is the acceleration with which the building is moved due to seismic activity. Duration, velocity and displacement: From the newton's second law, it is evident that acceleration is a key factor in determining the forces on a building. But there is one more criteria that we have to look into is the duration of the earthquake. Earthquake that has moderate acceleration, sustained over time, can cause much more damage to buildings than a single much larger peak. It weakens the building structure and reduces its durability. The strong–motion duration is often termed as "bracketed duration" (Arnold 2013). This is the shaking duration above a certain threshold acceleration value, which is 0.05g, and is defined as the time between the first and last peaks of motion that exceeds this threshold value (Arnold 2013). The strong motion ... Get more on HelpWriting.net ...
  • 5. Earthquake : The Seddon Earthquake In Seddon the aftershocks were a lot fewer but there were still 1,700 and only 45 being over magnitude 4. (see image 2). From the earthquake features discussed, we can see that despite the Seddon earthquake having a greater magnitude and similar type of fault movement, it was the fact that the Christchurch earthquake carried a lot more power and force with its initial ground movement and shaking, and its continual aftershocks, that the effects of this earthquake were much worse than the Seddon earthquake. In Christchurch, after the earthquake, more than half of the buildings in the central business district, around 10,000, had to be demolished, with a total of 100,000 homes damaged. Many heritage buildings were also badly damaged and some had to be demolished, with the most recognisable the Christchurch Cathedral. This damage in Christchurch was especially bad due to the effect of seismic lensing. Seismic lensing is caused during an earthquake when the p, s and I waves produced by the earthquake bounce of their surroundings. If these surroundings have hard surfaces the waves will rebound back in a similar direction to where they came from. Whereas if the surfaces properties are softer they can be ...

  • 6. The Great Chilean Earthquake : An Earthquake The Great Chilean Earthquake An earthquake is the shaking of the earth by seismic waves radiating away from the disturbance, most commonly fault movement. The great Chilean earthquakes origin was of the coast of Chile at a subduction zone, referred to as a hot spot for seismic activity. A subduction zone is a region on the crust of the earth where two tectonics plate meet one another. The area where the two plates meet is called a plate boundary. When two plates meet at a subduction zone, they converge towards each other, and one these tectonic plates come into contact with each other, one bends and slides underneath another, resulting in one curving down to the mantle. In this circumstance when subduction is taking place the denser plate is the one that sinks beneath the other. On the earth's surface there are two main types of crust; the oceanic and the continental. The continental isn't as dense as the oceanic making it slide above while the oceanic subducts down, in a convection motion to recycle itself then be remade when it pushes itself up. The place the denser medium goes towards is the mantle that consists of molten rock and it accounts to 84% of earths volume. Subduction only takes effect when two plates of different density collide, for if two continental crusts converge and push together neither will subduct, so it will be like a car crash where the two mediums smash into each other but neither subducts, as an example of this event look to the Himalayas that were ...

  • 7. An Earthquake Of The Francisco Earthquake Giovanni Lozano Professor Tod Benedict GLY 1000 21 October 2015 1906 San Francisco Earthquake An earthquake is the vibration of the Earth produced by the rapid release of energy. Most earthquakes occur at a plate boundary, usually along the Circum–Pacific belt. They tend to be caused by the slippage along large fracture in the Earth's crust, such as a fault for example. However, they can also occur from a volcanic eruption, or an atomic explosion. There are two different types of shocks to a major earthquake; there is a foreshock and an aftershock. The foreshock concedes of smaller earthquakes that precede a major one by some time period, and an aftershock that concedes of small earthquakes due to the adjustment of the crust after the major earthquake. Earthquakes affect numerous things, from soil liquefaction to construction, and the rupture of power, gas, and water lines. There are two ways to measuring the size of an earthquake, those are intensity and magnitude. The intensity is a measure of the degree of an earthquake shaking at a given locale based on the amount of damage, measured through the Modified Mercalli Intensity Scale which bases of the surveys of those whom were affected, and ranges from 1 to a 12. The magnitude is the total amount of energy released at the source of an earthquake, which tends to be measured on the Richter magnitude scale. This method is based on the amplitude of the largest seismic wave, and ranges from a –2 to infinity. Unfortunately there ... Get more on HelpWriting.net ...
  • 8. Earthquake Of The Sichuan Earthquake The Sichuan Earthquake also known as Wenchuan Earthquake occurred on May 12th, 2008. The horrific earthquake was located in the mountainous dominant region of Sichuan, south–western China. The earthquake was measured to have a magnitude of 8.0 by the Chinese. The quake affected four–fifths of the buildings located in the area. Towns, villages and schools had collapsed and had been destroyed. Close to 90,000 people were tallied as missing or dead. The Chinese Government report stated that more than 5,300 Children (mainly students at school) were killed by the quake. As well as 375,000 people injured from collapsing buildings and tumbling debris. The Chinese government sent relief workers and 130,000 soldiers to the devastated location. Yet remote villages were hard to reach due to the insignificant amount of usable rescue equipment needed to clear the damage (Pletcher, n.d.). 4,800,000 people (BBC, 2013) were left homeless due to the earthquake. The prediction of earthquakes cannot be tallied as a certain thing at the present time, however educated estimations can be used to develop and warn people of possible earthquakes. Predictions can and are based on a few factors. One includes new cracks in rocks, this occurs due to a great build–up of energy. That could possibly lead to a site where a discharge of energy could take in the nearby future.

  • 9. On Earthquakes Essay On Earthquakes An earthquake is a shaking or trembling of the crust of the earth caused by underground volcanic action or by the breaking and shifting of rock beneath the surface. The volcanic action and shifting rocks create strain which continues to build to a sudden release of pressure resulting in a shock wave. The vibrations produced in the crust can vary from barely noticeable to enormously destructive. Shock waves can be classified into two broad categories. Waves that send particles oscillating back and forth in the same direction as the waves are traveling are called primary. Primary waves, sometimes called compressional waves, travel through the earth beneath the crust. Secondary ... Show more content on Helpwriting.net ... The modern seismograph was invented early this century by a Russian seismologist, Prince Boris Golitzyn. This device made possible the modern era of earthquake research. Although earthquakes have occurred and affected mankind for as long as humans have been around, historical records are either lacking or considered unreliable before the middle of the 18th century. However, some records do exist and date major earthquake events back to 425 BC when one occurred off the coast of Greece resulting in an island named Euboea. Another occurred in Asia Minor about AD 17 and another leveled much of the Roman city of Pompeii in AD 63. During the Middle Ages, severe earthquakes struck England, in 1318; Naples, Italy, in 1456; and Lisbon, Portugal, in 1531. Casualties from major earthquakes have resulted in the greatest disasters in history. The worst occurred in 1556 in the Shannxi (Shensi) Province in China and killed an estimated 800,000 people. During the 18th century, the Japanese city of Edo (site of modern day Tokyo) was struck and killed 200,000. Earthquakes in Sicily in 1693 and Lisbon in 1755 each killed about 60,000 people. In 1797, approximately 40,000 died when Quito, Ecuador was struck. Historically, the most powerful earthquakes to strike North America occurred in 1811 and 1812 in southeastern Missouri.

  • 10. How Does Earthquake Affect The Earthquake Task Two: Earthquakes and Buildings The type of buildings that were the most damaged in the 2011 Christchurch earthquake. In the 6.3 magnitude Christchurch earthquake that occurred at 12.51pm on the 22nd of February 2011, the types of buildings that were the most damaged were houses and commercial buildings that were built in the 19th and early 20th century. The majority of these buildings that were damaged were ones that relied on single or double brick for their structure. This relates to how the bricks are placed on the house and whether there are two layers or one layer of brick. Buildings made of bricks and stones were damaged because they can't move with the earth and most of the bricks crack and fall off making the structure a lot less stable and more likely to collapse in an aftershock. Brick chimneys on the old wooden houses fell over and crashed through the roofs and caused a lot of damage. Stone buildings such as the Old Stone House were also badly damaged and had to be closed following the February 2011 earthquake. The most structural damage mainly occurred in houses that were made of heavy materials such as stones, bricks or concrete. This is because it is harder for these building materials to withstand strong shaking and to support their own weight when they begin to lose shape. They can't bounce back as easy once they have been forced in the other direction. This forces the buildings to fall outwards or collapse. A lot of damage occurred in houses and ...

The location where it occurred at is a part of Italy, in Italy Pompeii,and Mount Vesuvius(See appendix A map for visual location). Sixteen years after the tell tall in 79AD, Mount Vesuvius erupted again. A seismometers was used to measure the magnitude of the earthquake of Pompeii that caused the eruption of Mount Vesuvius. The topics that will be studied are, what is an earthquake, what causes an earthquake,impact of what earthquakes have on the world, and Pompeii today and earthquakes today. An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault of fault plane. The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. There are four types of earthquakes tectonic,volcanic,collapse,and explosion. Another good topic to study is deeper into the science of earthquakes.

In fact, the tsunami is the greatest cause of damage during the quake. In the tragic event, 15,890 people perished, 2,590 people reported missing, and 6,152 people suffered injuries in Japan–– most of which as a result of the tsunami. The 2011 Japan earthquake could not have been prevented, since natural disasters cannot be avoided, nor predicted; however, several steps could have been taken to reduce the number of buildings damaged. The Japanese government possesses good communication with their people (hence the issued tsunami warning), so the loss of life could not have been avoided. Despite strong communication with the public, the Japanese government could implement building regulations to withstand severe earthquakes and issue an "early warning" messaging system because sometimes, seconds make a difference. Today, the Japanese government is actively working to reduce the amount of nuclear power plants to avoid future complications with radioactivity and public health.

Earthquakes mainly occur on the boundary of two tectonic plates, known as fault lines, as the plates move against each other and get stuck which creates a strain and results in rocks breaking. This releases energy into the lithosphere (crust and upper mantle) causing shaking of the earth's surface. The energy released is called seismic waves and these are measured on a logarithmic scale called the Richter scale. ¬¬¬¬¬ Effects of Earthquakes (human or physical) Ground shaking and unstable buildings are some of the short–term physical effects that are caused by seismic waves.

Communication systems can be affected so most will set up plans for contacting friends and family. Immediately after an earthquake looting often happens as many will be without supplies however some people react very differently and try to help as many people as they can. Countries around the world will send money and food; some may even send volunteers to help and administer first aid. The rubble will be cleared to free the people trapped. Buildings being made safe is another way they would help but depending on the country's funding it doesn't always happen immediately. Tourism may decrease as the tourists could be scared of another earthquake or aftershock occurring. Long–term responses would be things like building restoration because aftershocks are not unusual. Before or after restoration begins an investigation may be required to figure out why the building collapsed and if there were any faults in construction. The economy will be negatively affected as rebuilding is costly and normal work is prevented from happening for quite a while. Whilst there are investments made for rebuilding and aid is sent in the immediate aftermath, families may struggle with reduced incomes and replacement of clothing and household items.

Plate tectonic activity is related to many other things like, volcanoes and earthquakes. These natural hazards can be found in linear belts around the globe. There are seven large plates and many small ones, the main types of plates include the divergent plate boundary (pulls away), convergent plate boundary (move towards each other) and transform plate boundary (slide past). Ocean–continent boundaries create earthquakes up 700 km deep and forms seafloor trenches, it leads to andesitic volcanoes in mountain ranges. Yellowstone is a 'hot spot' this is where heating and igneous activity occurs within crust. Although, not all plates move at the same rate, they are relative to each other. Continent– continent boundaries with divergent can form rift valleys, earthquakes less than 100 km deep, and basaltic/rhyolitic volcanoes. At Convergent they have young mountain range, 300 km deep earthquakes, and no volcanoes. At transform, they have a fault zone, less than 100 km deep earthquakes and again no volcanoes. With ocean–ocean boundaries there is oceanic ridges with rift valley, less than 100 km earthquakes, and basaltic pillow lavas at divergent. On convergent there are seafloor trenches, 700 km earthquakes and andesitic volcanoes in island arc.

  • 16. Dangers Of Earthquakes 1. What are some of the dangers of having an earthquake in large cities? There are many significant dangers of having earthquakes in large cities such as – Large amounts of people being at risk – Lots of large structures such as buildings – Set off landslides – Tsunamis The devastation of the Earthquake can differ depending on the location and environment of the country the Earthquake occurs. Countries that have fault lines close to the ocean are more at risk of having large Tsunamis. These waves can reach speeds of up to 500 kilometres per hour and cause massive devastation to anything in their path (ABC 2017). Some places such as New Zealand are more likely to have things such as landslides since the country has large amounts of hills and countryside. 2. What are 2 ways to make building that survive earthquakes? You may include a diagram to help you explain. 1. Buildings are designed to support the walls, roof and all the stuff inside to keep them standing. Earthquakes present a lateral/sideways, load to the building structure that is a bit more complicated to prepare for. One way to make a simple structure more resistant to a quake is to tie the walls, floor, roof, and foundations into a rigid box that holds together when shaken by a quake (Imagination Station 2017) 2.

  • 17. The Disaster Of A Earthquake The year 2010 was an active year for earthquakes and other natural disasters, racking up a total of four earthquakes ranked 7.0 or higher. Two of these quakes were merely a month apart, and started the year in a very destructive way. The first was a 7.0 in Haiti, the second over 3,000 miles away in Chile, an 8.8. Though both ravaged their countries, one was decidedly more devastating than the other. Looking at the magnitudes of the quakes, you might think Chile received the worst of it, but after further inspection, you may not be so sure. While the magnitude of a quake can be a big factor in the corresponding effects, the infrastructure of the affected area plays an even larger role in the number of casualties and the amount of devastation that is experienced. This devastation is further increased in coastal areas due to the high likelihood of tsunamis shadowing high magnitude quakes. The evening of January 12, 2010 was met with tragedy as a powerful 7.0 earthquake rattled the coast of Haiti. The epicenter of the quake sat close to the town of LГ©ogГўne, a mere 15 miles from the island nation's capital.

While other hazards such as volcanos, tornados, floods, and wild fires all have clear visual indications that allow for us humans to get away from them, earthquakes are much more insidious than the aforementioned disasters because they have no such indicator and the damage they inflict is near instantaneous. Luckily for us humans, seismologists have spent a good portion of the 20th century finding out why earthquakes occur, how to predict earthquakes that have not happened yet, and how to minimize damages caused by earthquakes with the help of extremely talented structural and seismic engineers. Our group will be examining four specific earthquakes occurring near Plate Boundaries that have had a significant impact on nearby communities, the damages and loss of life caused by these earthquakes, and how the communities that live near hotspots have adapted to the omnipresence of seismic activity. The first earthquake we will be talking about is the largest earthquake to occur within a U.S territory and the second largest recorded earthquake on earth, the Alaskan Good Friday Earthquake. The earthquake, lasting approximately 5 minutes, occurred Friday, March 27th at 1736 local time and was caused by the subduction of the Pacific Plate under the North American Plate.

Unlike hurricanes and tornadoes, they can awaken at almost any point in time throughout the year. These two natural disasters are also different from others because they occur on the layers of the earth itself. Volcanoes, while large to us, are actually small, conical patches of earth that spurt and ooze hot molten lava from the core, and can destroy areas of land triple their size. Earthquakes, on the other hand, are severe jolts felt on land due to the movement of earths tectonic plates. Some may describe earthquakes as being similar to riding a bike down a flight of stairs. The impact of an earthquakes can take down even the largest buildings and strongest structures. All natural disasters can have damaging effects on land, some more than others, and all can be measured or predicted in different ways. Although earthquakes and volcanoes are similar to each other, the two are still very comparable. A few of these similarities and differences include the cause of their occurrence, and how their occurrence impacts the environment.

  • 22. Earthquake Intensities Earthquake Intensities Earthquakes are a marvel of geology. When faults under the surface of the earth move, the ground moves. These earthquakes can be very mild, barely registering or they can be horrific with far–reaching consequences. Scientists have become fascinated with the study of earthquakes for centuries but it is only in recent years that quantified data has been collected and analyzed by scientists regarding these geologic phenomena. Before the invention of the Richter scale, less accurate means of measuring an earthquake's intensity were used by geological scientists. Until the early 1900s, earthquakes could only be measured after the earthquake had ended and then only approximations could be made. The first attempt at scientifically measuring an earthquake's intensity was performed in the middle of the nineteenth century. In Italy in 1857, the after effects of an earthquake were quantified (Lutgen 2011, page 179). A map was created to show the comparable damages that were found in different areas. This allowed geographers to make maps which would show the areas of highest intensity and how intensity lessened in surrounding areas. Although this was helpful, it only showed comparative intensities, not quantified data. In 1902, Giuseppe Mercalli developed what was called the Modified Mercalli Intensity Scale. An American version of the Mercalli system was incorporated in 1931. This system judged intensity of earthquakes based upon the ways California ... Get more on HelpWriting.net ...

He made tests, drew a world map, and recreated earthquakes only to find that rocks are being overstressed at the faults. "A fault is the place where two plates meet and are rubbed against each other" (Groiler Electronic Publishing, Inc.). The book, Predicting Earthquakes, the author points out "There are generally three kinds of faults: normal, reverse, and strike–slip. By careful observation and measurement, geologists, acting like detectives, can tell how much a fault moved, which part went up, which part went down, and which way the fault moved" (Vogt 26). "When one of the plates slip under the great amount of stress at the fault, anearthquake occurs. The shaking we feel are the passing of long waves" (Putnam 443). "The L–waves (long waves) travel at slower velocities that the primary and secondary waves. These waves make the largest squiggles on a seismograph but their effect diminishes rapidly with distance. The L–waves are limited to the crust" (Putnam 443). One of the two kinds of waves are "Primary waves are a kin to sound waves, and thus produce alternate compression and rarefaction in the medium through which they travel much like the waves that spread out through the air in all directions from a tuning fork" (Putnam 444). The second of the two kinds of waves are "Secondary waves, the particles in the rock through which the wave is traveling vibrate at right angles, or transversely, to the direction of

Since fundamental mode of the bridges always excited by the translational ground motions during earthquakes, transverse components of mode shapes only were described in this research to estimate the input of different bridge components on the bridge dynamic response. The frequency values obtained by each method, except of SSI for summer dataset, at each season and their mean and coefficient of correlation are shown in Table 3.1 and Table 3.2. From this figure, the values of fundamental transverse frequency identified by each method are highly correlated for all methods, the mean coefficient of variation was no more than 0.02. In addition, no relationship between the transverse frequency and the depth of frozen soil at specific dates was observed. A high correlation between mode shapes, with MAC value 0.95 or higher, was observed for two frequency domain methods only, FDD and EFDD. Therefore, the average values of natural transverse frequency calculated from the values identified by each method, 7.69 Hz and 2.85 Hz, and mode shapes obtained by FDD technique (Figure 3.1) were chosen as a baseline experimental values for the further calibration of the numerical models developed for winter and summer respectively.

Earthquakes With Earthquakes Earthquakes: The Same Effects, but Different Responses Earthquakes occur as a result of the abrupt release of energy in the Earth's crust that creates a series of waves known as seismic waves. Earth quakes greatly affect people whether they are living in economically disadvantaged countries or in economically developed countries. However, the way each of them responds to the hazard is different. The tectonic movements in the earth's crust are the initial causes of earthquakes. These movements bring about forces of tension and pressure, these forces stress up the earth's crust. As the stresses increase, an imbalance in equilibrium of the rocks which results into breaking of rocks and displaced. The energy accumulated during the process is released giving raise to waves. The waves cause vibration of objects they come across with causing a lot of impact on them. This may include shaking and rapture of the ground. As a result there is damage of infrastructure, landslides, fires due to damage caused to electric and gas lines.

A Brief Note On The Earthquake Of Earthquake Abstract Earthquake engineering is a subject where a person can be overwhelmed with information but still crave for knowledge due to its unpredictable nature. Earthquakes are a natural repetitive occurrence on planet earth, which due to its devastating impact, have caused a lot of damage to structures and caused loss of life. Therefore engineers, scientists and geologists were required to take action and one of the many first steps was to identify the regions of seismic activity. The argument in this essay is not how to prevent earthquakes as that is out of the control of humans but how to minimise the damage and deaths caused by them by designing better buildings. The challenge to first achieve this goal was by engineers in America, where in 1906, in the state of California, due to the frequent earthquakes in the state, building design codes and safety standards were established. These design or seismic codes have helped to reduce the damages caused by earthquakes. Therefore the solution for people in active seismic zones is to adhere to the seismic codes strictly, designed by engineers in order to help strengthen buildings and reduce the loss of life when an earthquake occurs. The greatest number of earthquakes occurs in Asia, America, Caribbean Islands and Europe but according to Hyndman, D and Hyndman, D (2012), earthquakes do not actually cause the death of people but the falling debris and buildings do.
