Mount Saint Helens is a volcano located in southwestern...
Mount Saint Helens is a volcano located in southwestern Washington. It is 8,363 feet tall.
Geologists say that Mount St. (Saint) Helens is a stratovolcano, also known as a composite volcano.
Stratovolcano is a volcano that is built upward because of layers of hardened volcanic ash, lava, and
other volcanic debris. These kinds of volcanoes are distinguished by their steep sides. They often
erupt extremely explosively, putting people and properties nearby at risk.
The present–day name, Mount Saint Helens, was received in 1792 by a man named George
Vancouver. He was captain of the British Royal Navy, at the time. The name was given in honor of
the British Ambassador of Spain, Alleyne Fitzherbert, who had the title Baron St. Helens. Three ...

II. ERUPTIONS
Many recorded and known eruptions of Mt St Helens dates all the way back to the 19th century.
Early settlers and some Indians staying in the local area observed infrequent eruptions. Mount Saint
Helens was more active than expected throughout a 26 year interval from 1831– 1857. Scientists
believe that it may have erupted a little over a century before that, in 1800. After that possible
eruption there was no activity until 1831. After the eruption in 1857, Mt Saint Helens only gave off
little steam outbreaks; after that, nothing more had occurred. The little steam outbreaks had occurred
in 1898, 1903, and 1921. Due to the fact that no activity had happened for 123 years, the
predominance of the residents in the 20th century described Mt St Helens not as a hazardous threat,
but as a beautiful, calm mountain.
The most previous, recorded eruption was happened on May 18, 1980. At 12:36 pm, Mount Saint
Helens began erupting steam and ash about 6,000 ft. (feet) into the air, above the volcano. The
actual explosion, releasing lava and ash, produced a 250 ft. (foot) wide crater. About a month
afterwards, a second moderately bigger crater formed. The two large craters combined together to
create one colossal crater in the volcano.
III. EFFECTS OF THE EXPLOSION
The lethal eruption killed 57 people, including geologist David Johnson, due to ash fall, thermal
injuries, and agony. Traffic accidents during the explosion killed 4 people.

Pros And Cons Of Living On Volcanoes
The pros and cons of living and farming on volcanoes are the ashes of the volcano is very good for
the crops and plants. A pro for living on a volcano could be , when the volcano erupts the minerals
help make the soil fertile. There are also many cons of living and farming on a volcano.
One of the various cons of living and farming on volcanoes is that the crops and plants get burnt
during the eruption from a volcano and that affects the farmers resources. Another con of living and
farming on volcano is the decreasing amount of sugar being produced by the autotrophs due to the
lack of oxygen. If the ash and mud from a volcanic eruption mix with rainwater or melting snow
fast moving mudflows are created, these are called mudflows, they destroy

Volcanoes Stereotypes
Volcanoes are fascinating things that get stereotyped. Many people think of volcanoes are a
destruction to Earth. In reality they help the Earth in many ways. Volcanoes enrich soil, creates jobs,
and form beautiful scenery.
Over 10,000 years ago a humongous volcano erupted in Naples, Italy. The debri and ash from the
volcano has enrich or improved the soil. This soil has gained nutrition and other minerals making
the soil great for plant growth. The crops there have been intensely growing for over 2,000 years.
Plants are reacting to the soil fertilization very well. The soil is making it easier to grow crops, the
soil has allowed the plants to really set their roots and start growing. Volcanoes also help farmers
because of the enriched soil.

Dbq Volcanoes
Many, many volcanoes exist. However, some of these are dormant while others are active.
Volcanoes tend to switch between these two roles. A volcano that was dormant a few years ago may
be active now and a volcano that was active a few years ago may be dormant now. This can create
many benefits in the area around the volcano, whether it be very close or very far. Volcanoes have
affected the environment throughout the years. Volcanoes have affected the environment throughout
the years in many ways, good and bad. Some of the bad things to which have happened because of

One of the many great things that happens after a volcano's eruption is enrichment of the soil around
a volcano. Volcanic eruption creates a large amount of rock and ash within the area to which the
eruption occurred, (Source Two: Volcanic Soils, paragraph one, lines one and two). The rock and
ash released from a volcanic eruption offers a bountiful amount of minerals that seep into the soil. If
you were a plant, growing in this soil would be like eating at Golden Corral every night of your life.
Along with this, the volcanic soils easily trap moisture, giving farmers a much easier job tilling the
ground, (Source Two: Volcanic Soils, paragraph five, lines two and three). If a volcano were to be
erupting near water, then the lava will become cooled into rock and eventually stack up. This is the
case for the islands that make up Hawaii. As the lava poured over the peak of the volcanoes and
trickled down the sides, it eventually came into contact with the water. This would cool the lava
down to the point of becoming solid rock again. After a very long time, the volcanoes made a long
stretch of islands, still growing each day. Some of these volcanoes are explosive, but the rest are
another type of volcano. These volcanoes do not explode violently as it spews molten rock and ash
into the air and land below. Rather, the lava grows to the top of the volcano to pour over the edge. A

Negatives Of Volcanoes
Many people claim how dangerous a volcanos is but, are they really that dangerous? They may have
caused some tragic outcomes throughout history, like Pompeii, but the real question is: How do
volcanoes effect people and environments? Ash and minerals from volcanos enhance the soil with
nutrients. As stated in paragraph 1 in Volcanic Soils "These deposits are rich in minerals, but the
minerals are not immediately available to plants. Depending on the location of the volcano, it can
take thousands of years of weathering for the ash and rock deposits to form a rich soil. When they
do become soils, they are often among the richest soils on earth." Also stated in paragraph 3 " Once

The truth is it depends on how you use the word "active". "Roughly 60 volcanoes erupted each year
through the 1990s; 154 in the full decade of 1990–1999; about 550 have had historically
documented eruptions." (Simkin 26) "Because dormant intervals between major eruptions at a single
volcano may last hundreds to thousands of years, dwarfing the relatively short historical record in
many regions, it is misleading to restrict the usage of "active volcano" to recorded human memories:
we prefer to add another identifying word, historically active or Holocene volcano" stated in
paragraph 1 of "how many active volcanos are there?". This states that even though some volcanoes
are still "active" it shows that they stay in dormant levels from a few years to hundreds and
thousands of years. So to conclude, there are many elements that go into how volcanoes affect
people and nature. Its helps with crops and puts minerals and nutrients that help with plant life. Also
that in order to get these results we need volcanic eruptions and without noticing it there are a lot of

Taking a Look at Volcanoes
Volcanoes are the eruption of magma, a mixture of rock, crystal, and dissolved gas, expelled through
the earth's crust onto the surface of the earth. Volcanoes consist of the following; a deep magma
chamber where magma accumulates, pipes that lead to surface vents, and the vents through which
lava is emitted during a volcanic eruption. They occur at three main settings, namely; along
subduction zones, a mid–oceanic spreading centres, and above mantle plumes. Environmental
effects are determined by the size, explosivity, magma chemistry, and geological location. Volcanoes
affect the climate through gases and particulate matter ejected into the atmosphere during an
eruption. However, the sulfur content determines the impact on climate rather than the size of the
explosion. The effect of volcanic gases and dust may warm or cool the earth's surface depending on
how sunlight interacts with volcanic material. Volcanoes can be divided into two types; effusive and
explosive. Both types of volcanoes have the potential to eject large volumes of gases into the
stratosphere to causes severe short–term climatic effects and possibly trigger long–term climatic
change on a continental and global scale. Effusive volcanoes have low viscosity and low gas content
with quiet non–explosive eruptions. They form shield volcanoes with freely flowing basaltic
magma. In 1783, the Laki eruptions in Iceland lasted 8 months producing 14 cubic kilometers of
basaltic lava. It produced an ash cloud

Volcanoes
Many people underestimate the power of volcanoes and the amount of damage they can do to a
country, state, city, or town. A volcano is a mountain that extends down to a caldera which is a pool
like are of magma in between the mantle and the crust in the Earth. It in a sense is a massive hole in
the middle of the crust and mantle of the Earth where magma can erupt from and eventually make
its way to the Earth's surface. Volcanoes are estimated to kill almost 1,000 people per year and
caused $99,000,000 worth of economic damages from 1980 to 2008. When an active volcano erupts
its "danger zone" is about a 20 mile radius around the volcano itself, which ends up killing people,
destroying houses, land, etc.
Known worldwide is the volcano of Tambora. On April 5th, 1815, many people didn't think it would
be their last day of their life. This volcano has one of the most tragic stories with the most deaths
recorded by one single volcano in history. The volcano of Tambora killed 80,000 people directly and
indirectly (Farrell,J). Most of the people that died were from Sumbawa Island and a lot of people
died later on due to starvation because the lack of food and disease. This volcano is located on
Sumbawa Island which is on the eastern end of the Indonesian archipelago. What made it so
dangerous was that there were no signs that there would be such a large eruption much less one at
all for thousands of years. So

Hawaii Volcanoes Essay
There are many different types of volcanoes in the United States. Composite, Ciner and Shield are
the three types of volcanoes. Over the history of Hawaii, covering about 85 million years, there have
been 129 volcanoes formed due to the hot spot and of that 129, 123 of them are extinct or
seamounts. In Hawaii today, there are currently five active volcanoes, Lo'ihi, Kilauea, Mauna Loa,
Hualalai and Haleakala. Lo'ihi is the only underwater volcano in Hawaii; the other four volcanoes
are above sea level. Kilauea is a hyperactive shield type volcano. Volcanoes are mainly found where
tectonic plates are diverging or converging. The Mid Ocean Ridge is an example of divergent
tectonic plates pulling apart, where the Ring of Fire is an example of convergent tectonic plates
pushing together. Hawaii today is comprised of many different volcanoes with several different

Lo'ihi is an underground seamount which reaches about 3,000 meters above the sea floor. Before,
people did not consider Lo'ihi to be an active volcano, instead just a common old seamount volcano,
the same type to surround the islands of Hawaii. After doing some research it was discovered that
this volcano was in fact an active one, instead of an old dead seamount. "In August 1996 Lo'ihi
volcano rumbled to life again with a vengeance and has been intermittently active since. In fact,
University of Hawaii scientists studying the seamount following the 1996 seismic swarm have
found direct evidence of a volcanic eruption there in 1996, making this the first confirmed historical
eruption of the seamount." (Ken Rubin and Brian Glazer, 2014). Today, Lo'ihi remains quiet but in
recent years such as in 2005, Lo'ihi had about 100 earthquakes beneath her and in 2006 she had an
earthquake reported with a magnitude of 5.1 and

yet, maybe the person packing the parachute does know you. Furthermore, while dangling from

The majestic mountain towers over the Washington state landscape and can be visible from most
vantage point in the Seattle metro area. See the main Seattle page here. Mt. Rainier is an active
volcano that is always topped with snow. It has 26 main glaciers – the most on any mountain in the
lower 48 US states. It is more than 14 thousand feet high and spawns 6 major rivers and many
waterfalls. The national park around the mountain was established in 1899 as the fifth national park
in the United States and it encompasses 236,381 acres. Along with the towering peak of Rainer, the
park's expansive area includes many mountains, meadows, old growth forests, rivers and waterfalls.
Interesting Facts: On clear days Mt Rainier can be seen as far away as Corvallis, British Columbia

Volcanoes In Ecuador
Ecuador is a small country on the Pacific coast of South America. It is bisected laterally by the
equator, and longitudinally by the Andes. The Andes divide the country's mainland into three

Andes are extremely volcanic, containings most of the active volcanoes in the Northern Andes

When the volcano has an eruption, the hot material issued from the crater melts portions of the

lahars. According to Aguilera et al, (2004), "pyroclastic surges and flows that swept over the glacier
ice cap are probably the most effective at melting large amounts of snow and ice, which can result in
quasi–instantaneous release of large masses of water and volcanic debris" (p. 165). About 4,500
years ago, Cotopaxi experienced the Chillos Valley Lahar, the largest debris flow in the Northern
Andes during the Holocene period (Mothes, Hall, and Janda, 1998, p. 233). The total volume of the

Affects of Volcanoes
The plates which are about 20 miles thick, make up the earth's crust and are a chief cause of
volcanic activity. These plates are always in motion. They move very slowly, however some at times
bump in to each other. These movements put a lot of pressure on the surface rock. Volcanoes obtain
their energies from such movement and pressure. Volcanoes form at the boundaries of these plate
where two types of movement occurs, two plates will collide with each other or the plates will move
apart from each other. Some of these plates layers are cooled and are made up of rigid rocks.
The affects on the landscape is lava that ... Show more content on Helpwriting.net ...
Also lava flow is more life threatening but can produce a lot of property damage as well as
economic loss. Volcanic ash can collapse roofs and damage crops, especially if they become wet
from rainfall. Debris flows called lahars that are mixtures of volcanic debris and water made from
melted snow or ice or heavy rainfall. If anything comes in the path of lahar can destroy and also
travel quickly through valleys.
Indirect hazards are usually non volcanic effects that accompany or follow eruptions. Examples are
rainfall–caused debris flow, and post eruption disease and famine. Tsunamis are large seismic sea
waves generated by sudden movement of the seafloor. This sudden seafloor movement can be
caused by a large earthquake or by the collapse of an island volcano during or after an eruption.
Tsunamis can devastate low–lying coastal areas and can be deadly if people living in such areas are
not evacuated. Indirect hazards also include volcanic deposits from large eruptions. These deposits
can blanket farm fields and grazing lands, leading to the loss of crops and livestock and ultimately
to the starvation of people dependent on them for life. During the period from the 17th century to
the 19th century, tsunamis and posteruption starvation and disease caused most eruption–related
deaths.
Possible future activity can be noticed sometimes by predicting the next

Most Types Of Volcanoes Are Shield Volcanoes, Scoria Cones...
1. The major types of volcanoes are shield volcanoes, scoria cones (cinder cones), and
stratovolcanoes (composite). Each of these volcano types is influenced by the volume, the amount
of magma, viscosity, a measure magma's fluid friction, and volatiles or dissolved gases, of the
magma that creates them. Shield volcanoes form from the solidification of lava flows of basalt
(Abbott 2014). These large volume, low viscosity, low volatiles magma flows travel great distances.
As thousands of layers of lava flows cool on top of one another other, volcanoes are formed over a
long period of time. The width of these volcanoes is greater than their height, for example Mauna
Loa in Hawaii. Scoria or cylinder cones are low height conical hills formed by basaltic and andesitic
pyroclastic debris collected near a volcanic vent. Scoria cone magma is of small volume with
medium viscosity and medium volatiles. At the top of these cones are summit craters usually less
than two kilometers in diameter which may hold magma lakes during an eruption (Abbott 2014).
Additionally, lava may also drain from the base of scoria cones. Stratovolcanoes or composite
volcanoes are steep sided and symmetrical, examples include Mount Kilimanjaro, Mount Rainer,
and Mount Fuji. The peaks of composite volcanoes are built of alternating layers of pyroclastic
debris capped by high viscosity andesitic to rhyolitic lava flows that solidify to form protective caps
(Abbott 2014). Magma of stratovolcanoes is of high

Essentially, the key fact that makes the islands of Hawaii so unique and worthy of studying is that
nearly the entire mountain range is built entirely by volcanic activity and each island is the top of an
enormous volcanic mountain. These exceptional qualities fuel the study of how the islands
themselves were created, in order to answer the curiosities behind the composition of some of the
most extravagant volcanoes in the world.
III. History of the Hawaiian Islands
The basic theory of plate tectonics says that all volcanic activity should occur between lithosphere
plates (Physical Geology). However, the Hawaiian Islands bend this rule by being located directly in
the middle of the Pacific plate. The Hawaiian volcanoes are known as intraplate volcanoes. This
may not seem possible because it disrupts the rule of plate tectonics, but there's the exception of a
hot spot. T. Wilson suggested that the Pacific plate moved in the northwestward direction over a
melting spot deep within the mantle, and this hot spot remained relatively stationary and supplied
magma to the moving Pacific plate to form the Hawaiian Island chain (Volcanoes in the Sea). In
order to prove this suggestion, the structure of the Hawaiian Islands must be in line with a hot spot
origin. This will be

Earthquakes : Volcanoes And Earthquakes
Volcanoes and Earthquakes are Sisters, Not Twins
Volcanoes and Earthquakes are two of the most intriguing natural disasters that can occur on earth.
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.
Earthquakes and volcanoes are both similar in the fact the earthquakes can cause volcanoes to form
or even erupt, but the severity of their damage is caused by different factors and result in different
outcomes. The earth can be structurally compared to an egg. It has a large hot core, a thick layer of

few places where you can walk continuously from shale or basalt into well–metamorphosed gneiss

Magma can also push up under the middle of a lithosphere plate, though this is much less common
than magma production around plate boundaries. This interplate volcanic activity is caused by
unusually hot mantle material forming in the lower mantle and pushing up into the upper mantle.
The mantle material, which forms a plume shape that is from 500 to 1000 km wide, wells up to
create a hot spot under a particular point on the earth. Because of the unusual heat of this mantle
material, it melts, forming magma just under the earth's crust. The hot spot itself is stationary; but as
a continental plate moves over the spot, the magma will create a string of volcanoes, which die out
once they move past the hot spot. The Hawaii volcanoes were created ... Show more content on

Because of this difference in density, the magma pushes upward with great force (for the same
reason the helium in a balloon pushes up through the denser surrounding air and oil pushes upward
through denser surrounding water). As it pushes up, its intense heat melts some more rock, adding to
the magma mixture.
The magma keeps moving through the crust unless its upward pressure is exceeded by the
downward pressure of the surrounding solid rock. At this point, the magma collects in magma
chambers below the surface of the earth. If the magma pressure rises to a high enough level, or a
crack opens up in the crust, the molten rock will spew out at the earth's surface.
If this happens, the flowing magma (now called lava) forms a volcano. The structure of the volcano,
and the intensity of the volcanic eruption, is dependent on a number of factors, primarily the
composition of the magma. In the next section, we'll look at some different magma types and see
how they

Big Island Volcanoes
During the Big Island trip, I learned the predictiction of volcanic eruptions, the study of volcanoes,
and the effects of a volcanic eruption. To start off, the Big Island is known for its active volcanoes,
meaning it constantly erupts and spews lava. Geologists actually has a way to forecast the eruption
of the volcanoes. "Seismometers can be used to pinpoint earthquakes which track the rise of magma
and its movement along fissures." (volcanoworld) This means that geologists uses seismometers in
predicting volcanic eruptions so they can warn people about it. In conclusion, geologists can predict
a volcanic eruption using multiple instrument, seismometer being one of them. Furthermore, I've
also learned the study of volcanoes which is called vulcanology. The people who studies volcanoes
are called vulcanologist, and they are also the ones who knows how to use complicated instruments
only used for vulcanology such as a retroreflector, which is an instrument that reflects light back to
its source, and a geodimeter, which is an instrument to measure the distance between two points of
laser beam. "A laser beam is emitted from the geodimeter, hits a retroreflector at a second point, and

During pre–eruption, geologists and vulcanologists are very alert on what is happening around the
volcano to see if it will have a huge effect on its surrounding, so after it erupted, these scientists
quickly see if there are any post–volcanic activities. Aside from the lava oozing and destroying the
volcano's surroundings, landslide is also one of the effects. "A tiltmeter located in the uplifting zone
detects the deformation by sensing the minute change in slope caused by the uplift." (usgs.gov) This
explains how a tiltmeter helps scientists in knowing if there are any post–volcanic effects. In
conclusion, a volcanic eruption can lead to a lot of events, such as ruined grasslands and

Volcanoes and Volcanology Essay
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known
volcanoes, 70 can be expected to erupt each year with at least one large eruption each decade
(Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the
beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping
giants grows. Due to this, the study of volcanoes and the service that volcanologists provide to the
public by way of information and predictions on activity is immeasurable. Named for the Roman
god Vulcan, volcanoes have both intrigued and frightened mankind for ... Show more content on

There are four major types of study that make up a volcanologist or team of volcanologist. These
include physical volcanologists, geophysicists, geodesic volcanologists and geochemists (What does
a volcanologist do?, n.d.). Physical volcanologists study the actual processes that make up a
volcanic eruption.
They also study the deposits made from the eruption. Where the rocks from the eruption were
distributed and what their makeup are. A geochemist can also determine the chemical makeup of
these deposits. By studying deposits and lava flows from past eruptions, it can assist in the
prediction of where the lava will flow, how far the debris field will be and how far the ash will
scatter in new eruptions. As retired volcanologist Robert Tilling so aptly described it, "the present is
the key to the past – In a sense, we're detectives, trying to decipher clues that rocks tell us." (What
does a volcanologist do?, n.d. para. 1). Volcano geodesists study the inner workings of a volcano,
basically, its plumbing. While a physical volcanologist and geochemist can study the results of a
volcanic eruption, without knowing the inner workings of a volcano, where the magma chambers
are located and which direction they go, it is sometimes difficult to know whether or not an eruption
will take place at all (Poland, Hamburger, & Newman, 2006). Geophysicists study the Earth and
their research regarding

Note on Volcanoes
Volcanoes Process Magma is formed when the lower crust or upper mantle melts as a result of
tectonic activity. This magma (and its various components) is discharged through a vent or opening
referred to as a volcano. Thus in basic terms, volcanic eruptions are caused by the rise of magma
from the earth's interior. According to Manroe, Wicander and Hazlett, in comparison to the
surrounding solid rock, magma tends to be less dense (107). In the authors' words, "the greater the
difference in density between melt and country rock, the faster magma rises" (Manroe, Wicander
and Hazlett, 107). It is however important to note that as magma gets close to the earth's surface, it
assumes a neutral buoyancy position (Manroe, Wicander and Hazlett, 107). This is brought about by
a drop in the contrast of density between melt and the surrounding solid rock. It should be noted that
if sufficiently shallow, magma in the aforementioned buoyancy position could still erupt. This
according to Manroe, Wicander and Hazlett could happen as a result of the buildup of what is
referred to as volatiles (107). It should also be noted that as it approaches the surface, magma
changes in terms of volatile composition. As Manroe, Wicander and Hazlett point out, the
assimilation of ground water effectively increases the melt's dissolved H2O content (107).
According to the authors, it is the expansion of dissolved water into steam that in some instances
triggers explosive volcanic eruptions. A volcanic

weeks of the eruption collecting information and making observations of the volcano and the areas
ecology – learning about things science has not had the chance to learn about until this time. Listed
below are a few of the things that the eruption of Mount
St. Helens has taught taught scientists:
● This was the first time this type of volcano eruption was actually witnessed and documented in
history. In 1956, there was a similar landslide and blast at
Bezymianny volcano in Kamchatka, Russia – however, there were no witnesses to document the

actual blast. It wasn't until Mt. St. Helens that it was recognized that the two blasts were the same
style of eruption.
● These "sector collapse" (the name of this type of eruption) have now been identified at over 200
volcanoes around the world. The detailed studies of the sector collapse, the lateral blast, and the
large mudflow of this eruption have led to the reassessment of volcano hazards at other sites around
the world. This has given these communities a way to become better prepared for future eruptions.
● Studies of Mount St. Helens has also demonstrated that volcanic eruptions can be accurately
predicted.

Volcanoes in Sicily
On the beautiful island of Sicily there are numerous volcanoes, which make this island even more
fascinating. It is the active geological activity that bestow this area those tempting volcanoes.
According to the Plate Tectonics, the island of Sicily is located on the common border of Eurasian
Plate and African Plate. And as two plate pushing against each other, this common border is called
orogenic belts, which means that orogeny – the process which continental plate is folded and
deformed by lateral compression to form a mountain range [1] – occurs in this area.
Since we mentioned volcanoes, we have to know that geologists divide volcanoes into different
categories according to their different shapes or eruption pattern. We can divide volcanoes into two
main types as their different appearances. Stratovolcano, usually appears as an elegant, refined,
symmetrical cone because this type of volcanoes produces viscous lava, and after multiple
eruptions, a perfect cone is formed [2]. As a result of its perfect shape, stratovolcanoes usually
attract many tourists. Example of this type of volcanoes would be Mount St. Helens in United
States, Mount Fuji in Japan and Mount Vesuvius in Italy. But not all volcanoes have perfect shapes,
shield volcanoes, which holds lava that have great fluidity, give them wide and gentle slopes, results
in shield–like shapes. This type of volcanoes is a lot larger than stratovolcanoes. The most famous
examples would be Hawaiian

Volcanoes In The United States
Volcanoes A volcano is a mountain that descends into a pool of molten rock below the surface of the
earth. When pressure builds up, eruptions occur. Various gases, rocks, and lava shoot up through the
opening, or vent, and spill over the land or pollute the air. Eruptions can cause damage to the
environment and make places uninhabitable. Scientists have researched volcanoes for centuries to
find the positive and negative effects volcanoes can have on the world and how to predict disasters.
Volcanic eruptions in the United States have been recorded for centuries. Some of the major

Learning about a volcano can help them predict when there will be another eruption. Volcanologist
can predict long and short term. They predict long term by studying the deposits, lava flow,
characteristics of past eruptions, they use radiometric age dating of deposits to determine past
frequency, and with this knowledge, they make volcanic hazard maps to help with the public to help
them know when to evacuate if there is ever a eruption (Nelson). Short term prediction is used by
monitoring magma when it is approaching the surface and monitoring other events that can make
another eruption, changes in the magnetic field can track down the magma movement, as magma
moves, the structure can inflate which causes deformation into the ground which can be monitored
and measured by tilt meters which measure the Earth's angle, when magma goes into a volcano, it
can cause water to rise or decrease causing the water's temperature to rise, and changes in heat flow
can be measured by using infrared remote sensing (Nelson). Predicting volcanic eruptions can help
people prepare and evacuate hazardous situations. Therefore, volcanoes have positive and negative
effects on the environment. Historical eruptions have helped scientists learn more about volcanos.
Knowing the types of volcanoes and how they form have helped predict volcanic eruptions.

Mount Rainier
Mount Rainier is a volcano that is in the Cascade Range in Mount Rainier National Park,
Washington. This volcano is 14,411 feet (4,392 meters) in its elevation. This is the highest mountain
in Washington. This volcano is in the same mountain range as Mount Adams, Mount Baker, Mount
St. Helens and Glacier Peak. It is known as a stratovolcano which is a large, steep volcano built up
of differentiated layers of lava and ash or cinders. This volcano is an active volcano and the last time
it erupted was in 1894. The largest eruption this volcano had was 2200 years ago. It has been
recorded that the areas has had a lot of small high–frequency earthquakes. Some of them occur
daily. According to geologist the cause of this is hot fluids moving inside the mountain. It is
composed of two overlapping volcano crater that are 1000 ft. around. This volcano has three
different summits; they are Columbia Crest, Point Success and Liberty cap, the highest which is
14,411 feet and the lowest which is 14,112 feet. It lies on the Juan de Fuca Plate. This is a divergent
boundary. It was formed by the subduction of the Juan de Fuca Plate and the North American Plate.
This volcano also has lahars which are large mudflows that happen in the deposits of sediments that
surrounds volcanoes; they can be hot or cold. This volcano includes but not limited to the rock
andesite.

Essay On Hawaii Volcanoes
Hawaii: Geology's Volcanic Wonder of the World It is well know that Hawaii is very volcanically
active and is home to the world's most active volcanoes. Hawaii is unique because the islands are
caused by a 'hot spot' in the middle of the Pacific Plate, one of the largest crustal plates on earth.
There are only a few 'hot spots' on earth and they occur in an area where the plate is thin and weak
creating volcanism, where molten magma ruptures the earth's crust. For Hawaii, the 'hot spot' is
under the sea floor, it creates under sea volcanoes. Over millions of years these volcanoes build up
to sea level and become islands. As for Hawaii, the Pacific Plate has moved northwest across this
'hot spot' creating what we know today as the Hawaiian Islands in the South Pacific Ocean. In all, ...

Volcanoes : Volcanoes Of Hawaii
Volcanoes of Hawaii With a population of 142 million people Hawaii is the home to the largest
volcanic islands. Hawaii is a state with eight main islands, which are Hawai'i, Maui, Oahu, Kauai,
Molokai, Lanai, Niihau, and Kahoolawe (Macdonald 3). On those islands, Hawaii consists of five
major volcanoes: Kilauea, Mauna Loa, Hualalai, Kohala, and Mauna Kea (Macdonald 59). Figure
3.2 shows a map of the 5 major volcanoes that make up the Hawaii Island (Macdonald 59). There is
one more major volcano, Loihi, which is considered a submarine volcano (Macdonald 4). However,
before learning about the Hawaii volcanoes we have to know how Hawaii itself was formed. Hawaii
was formed with the volcano of Kilauea, which lead more volcanoes to erupt. It has been theorized
that Hawaii is sitting on a hot spot under the Pacific plate, which has come to be known as the hot
plate theory (Macdonald 1). In Stanley's text Earth System History, a hot spot is defined as a small
geographical area where the crust is elevated by the rising magma that can cause a volcano to erupt
(192). These hotspots pushed the molten lava to the surface, which caused the sea volcanoes to
form. The volcanoes overtime rose to the surface of earth and formed the Hawaiian Islands. Then
the Pacific plate rotated northwest, which made room for more hotspots to occur, therefore, making
the eight total islands in Hawaii ("How Did Hawaii Came to Be", par. 2). However, nobody is
absolutely certain what exactly

The article, "Volcanic Soils", states that loam within the confines of Mount Vesuvius and the regions
its ejections once engulfed is so fertile that farmers frequently plant different crops intermingled
with one another in order to maximize the utilization of every square inch available. This practice is
called intercropping, and is highly esteemed for its pecuniary benefits. When implemented, it
enables the optimum exploitation of resources, provides indemnity against total crop failure, and
induces the greatest yield. Moreover, well vegetated volcanic terrains that kindle allure entice
tourists. For example, the article, "On the Slopes of Mauna Loa, Hawaii Island", visitors flock to
Highway 11, a route from the west coast of Hawaii that approaches the Hawaii Volcanoes National
Park. Travelers are mesmerized by the topography of the island, a profuse of greenery that was
stimulated by volcanic eruptions. Tourism wields tremendous monetary influence; it is one of the
world's most significant sources of economic stability. Tourism creates jobs, both through direct
employment within the tourism industry and indirectly within sectors such as retail and
transportation. When laborers spend their wages on goods and services, it gives rise to what is
known as the "multiplier effect", producing more jobs. The tourism industry also offers
opportunities for small–scale business enterprises, which is particularly salient in rural communities.
It engenders extra tax revenues, which can be used to generate funds for local institutions, including
schools and hospitals. Moreover, volcanic soils play an integral role in the lucrative dairy industry
of The North Island of New Zealand, which is bountiful in volcanic loam. Volcanic soils are
felicitous for pasture growth because of how well they retain water for plants, subsequently
resulting in verdant pasturelands. Volcanoes appease our materialistic

Identify The Different Types Of Volcanoes
There are three types of volcanoes on earth. They are composite, cinder cone and shield volcanoes.
They are all over the world and depending on what kinds of volcanoes they are they would be in
different areas because some volcanoes have little lava and some have a lot that can be very
dangerous if they were to irrupt.
The first type of volcano is the "Composite" volcano. This type of volcano has cinders, lava flows
and mixed with gravel like sand. "Hollywood" types are easily recognized, many are located in
popular areas; Vesuvius, Krakatoa, Fujiyama, and Mount St. Helens.
The second type of volcanoes, are "Cinder Cone" volcano. These types of volcanoes are mostly

Aztec Volcanoes Essay
The mythology of the Aztec peoples, which dominated central Mexico in the 1400's and early
1500's, described a universe of greatness and fear. In this Mexica civilization, volcanoes had a deep
spiritual as well as strategic military importance. The legend of the volcanoes, Popocatepetl and
Iztaccihuatl, is no different. The Aztec mythological explanation for the two volcanoes is a story of
love and war. In this paper, I will describe the legend behind these two natural locations and its
correlation with the spiritual and social importance of volcanoes to the Mexica people at the time.
In Aztec legends, worlds were formed as powerful deities fought among themselves. These gods
often took form through associations with common items such as numbers, colors, directions and
even calendrical events. Aztec spiritual life ranged from the crafting of small pottery statues in
representation of the gods to large scale events like attending elaborate public ceremonies involving
human sacrifice.
At the end of each fifty–two year calendrical cycle, the Aztecs would hold a ritual in which priests
would begin a fire at the top of a "volcano that overlooked the surrounding shimmering lakes"
(HARRINGTON). This event consisted of burning a specific person as sacrifice, lighting torches

viewed as sacred because clouds seemed to be connected over them (Plunket). He states that
pilgrimages to volcano peaks with offerings of water continued until the end of the 1500's (Plunket)
However, despite these allegations, there are no early sources which specify state who the volcano

How Many Volcanoes Are There
Imagine hiking up a dormant volcano and all of a sudden the volcano starts to rumble What's the
cause? The cause of the volcano occur when an underground chamber overflows creating an
explosion out the top of the volcano. Volcanoes can have effects on the land and its people.
When volcanoes erupt they can have some drastic but beautiful changes to the earth. The author of
the informational article, Russell McDonaugh, states that "Depending on the location of the
volcano, it can take thousands of years of weathering for the ash and rock deposits to form a rich
soil. When they do become soils, they are often among the richest soils on earth." Volcanic soils are
very fertile and can help plants grow very fast with the nutrients in the soil. Volcanos are very good
for the land maybe, after a couple thousand years, but sometimes the beauty of the nature is
destroyed by the ongoing building on our world.

Eurasian and African plates due to convection currents. This has caused the formation of the Mid–
Atlantic ridge. When two plates diverge, initially, a rift valley may occur. Magma rises from the
mantle filling in the gaps between the two plates, which can cause submarine volcanoes to occur,

Pelean eruptions are similar to vulcanian eruptions but have even more viscous lava; domes from
over the vents, and ash flows commonly accompany the dome fountais. Plinian eruptions, also
known as 'Vesuvian eruptions', are volcanic eruptions marked by their similarity to the eruption of
Mount Vesuvius in AD 79 (as described in a letter written by Pliny the Younger, and which killed his
uncle Pliny the Elder). Plinian eruptions are marked by columns of gas and volcanic ash extending
high into the stratosphere, a high layer of the atmosphere. The key characteristics are ejection of
large amount of pumice and very powerful continuous gas blast eruptions.
Risks
Volcanoes release volcanic hazards that may cause the life of human kind to be in danger. These
volcanic hazards are Pyroclastic Density Currents (pyroclastic flows and surges), Lahars, Structural
Collapse: Debris flow–Avalanches, Dome Collapse and the formation of pyroclastic flows and
surges, Lava flows, Tephra fall and ballistic projectiles, volcanic gas, Tsunamis and Volcanic
Lightning
Pyroclastic density currents are are gravity–driven, rapidly moving, ground–hugging mixtures of
rock fragments and hot gases. This mixture forms a dense fluid that moves along the ground with an
upper part that is less dense as particles fall toward the ground. The behavior of the fluid depends
