The document summarizes information about earthquakes, including:
1) Earthquakes are caused by a sudden release of energy in the earth's crust that creates seismic waves. The effects vary based on magnitude and intensity and can cause widespread destruction.
2) Key terms are defined, such as focus, epicenter, fault lines, and different types of seismic waves.
3) Earthquakes are measured on the Richter scale based on energy released. Different zones in India are classified by seismic activity.
4) Major earthquakes discussed include the 2001 Gujarat earthquake that killed over 20,000 people and left hundreds of thousands homeless.
An earthquake (also known as a quake, tremor or temblor) is is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to the people around and destroy whole cities.
A natural vibration of the ground or the earth crust produced by forces is called earthquake or seismic forces.
An earthquake is what happens when two blocks of the earth suddenly slip past one another.

Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. Earthquakes constitute one of the worst natural hazards
which often turn into disaster causing widespread
destruction and loss to human life.
The effects of earthquake vary upon the magnitude and
intensity. Earthquakes occur every now and then all
round the world, except in some places where
earthquakes occur rarely. The devastation of cities and
towns is one of the effects of earthquake.
3. What is Earthquake?
An Earthquake is the result
of a sudden release of energy
in the earth’s crust that creates
seismic waves.
The seismic activity of an
area refers to the
frequency,type and size of
earthquakes experienced over
a period of time
4. For example:
If you throw stone in a
pond of still water,series of
waves are produced on the
surface of water,these waves
spread out in all directions from
the point where the stone strikes
the water.
similarly, any sudden
disurbances in the earth’s crust
may produce vibration in the
crust which travel in all direction
from point of disturbances.
5. Focus(Hypocenter):
Focus is the point on the fault
where rupture occurs and the
location from which seismic
waves are released.
Epicenter:
Epicenter is the point on the
earth’s surface that is directly
above the focus ,the point where
an earthquake or underground
explosion originates.
6. Cont…
Fault Line:
A Fault line is the surface trace of
a fault, the line of intersection
between the earth’s surface.
Fault plane:
Fault plane are the crackes or
sudden slips of the land .
Fault Scrap:
A Fault scrap is the topographic
expression of faulting attributed
to the displacement of the land
surface by movement along
faults.
7. The primary cause of an earthquake is faults on the
crust of the earth.
“A Fault is a break or fracture b/w two blocks of rocks in
response to stress.”
This movement may occur rapidly, in the form of an
earthquake or may occur slowly, in the form of creep.
Earth scientists use the angle of the fault with respect to the
surface (known as the dip) and the direction of slip along the
fault to classify faults.
8. Classification Of Faults
Normal fault:
a dip-slip fault in which the
block above the fault has
moved downward relative to
the block below.
1.Thrust (reverse)fault:
Thrust (reverse)fault:
a dip-slip fault in which the
upper block, above the fault
plane, moves up and over the
lower block.
9. Strike-slip fault:
A left-lateral strike-slip
fault :
It is one on which the
displacement of the far block is
to the left when viewed from
either side.
A right-lateral strike-slip
fault:
It is one on which the
displacement of the far block is
to the right when viewed from
either side.
10. Some major causes of earthquakes on basic of its causes are:
Surface causes
Volcanic causes
Tectonic causes
Surface cause:
Great explosions, landslides, slips on steep coasts, dashing
of sea waves , avalanches , railway trains, heavy trucks, some
large engineering projects cause minor tremors. some of them are
man made, other are natural.
11. Volcanic cause:
Volcanic eruptions produce earthquakes. Earthquakes may
precede, accompany and frequently follow volcanic eruptions.
They are caused by sudden displacements of lava within
or beneath the earth crust.
There are two general
categories of earthquakes
that can occur at a volcano:
volcano-tectonic
earthquakes
long period earthquakes.
12. Tectonic cause:
Structural disturbances resulting in the parts of the
lithosphere is the main cause of this type of earthquake.
Most of the disastrous earthquakes belong to this
category and occur in areas of great faults and fractures.
Sudden yielding to strain produced on the rocks of
accumulating stress causes displacements especially along
old fault zones known as great transform faults.
Plate Boundary Overview.flv
13. Seismic waves produced due to
earthquake are basically divided
into two major types:
Body waves
Surface waves
14. Body waves:
Body waves travels through the interior(body) of earth as they leave
the focus. Body waves are further divided into following types:
Primary (P) waves
Secondary(S) waves
15. Primary Waves (P-waves) Secondary Waves(S-wave)
High frequency High frequency
Short Wavelength Short Wavelength
Longitudinal waves Transverse waves
Pass trough both solids and
liquids
Can not move through liquids
Move forwards and
backwards as it compressed
and decompressed
Move in all direction from
their source
P-wave is faster S-wave is more slower than P-
wave
First P-wave arrive After P-wave,S-wave is arrive
16. Surface Wave:
Surface waves travels parallel to the earth’s surface and these
waves are slowest and most damaging. Surface wave are divided
into following types:
Love waves
Rayleigh waves
17. Love Waves Rayleigh wave
Guided waves Guided waves
Displacement is parallel to the
free surface
Displacement is perpendicular
to love-wave displacement
Love wave is faster Rayleigh wave is slower
Causes horizontal shifting of
the earth surface.
Ground move in circular
motion.
18. The intensity and strength of an earthquake is measured on
Richter scale,the scale invented by Charles Richter California
,USA in 1935.which categories earthquake on the basis of
energy released.
Defintion:
“the logarithm to base ten of the maximum seismic-wave
amplitude recorded on a standard seismograph at a distance of
100 kilometers from the earthquake epicenter.”
Scientists measure the strength of earthquakes using
machines known as seismographs.
Seismology is the scientific study of earthquakes and the
propagation of elastic waves through the Earth.

3.0 179 Kilogram
4.0 5 Metric Tons
5.0 179 Metric Tons
6.0 5643 Metric Tons
7.0 179100 Metric Tons
7.5 1 Mega Tons
8.0 564300 Metric Tons
21. Seismometers are instruments
that measure motions of the
ground, including those
of seismic waves generated
by earthquakes, volcanic
eruptions, and otherseismic
sources.
Seismometers may be
deployed at Earth's surface, in
shallow vaults, in boreholes, or
underwater.
22. Zone - II: This is said to be the least active seismic zone.
Zone - III: It is included in the moderate seismic zone.
Zone - IV: This is considered to be the high seismic zone.
Zone - V: It is the highest seismic zone.
The earthquake zoning map of India divides India into 4 seismic
zones Based on the observations of the affected area due to
Earthquake india divided into four types of zones:
23.
24. Earthquake prediction is usually defined as the specification of
the time , location , and magnitude of a future earthquake within
stated limits.
But some evidence of upcoming Earthquake are following:
Unusual animal behavior
Water level in wells
Large scale of fluctuation of oil flow from oil wells
Foreshocks or minor shocks before major earthquake
Temperature change
Uplifting of earth surface
Change in seismic wave velocity
25. Loss of life and property
Damage to transport system i.e. roads, railways, highways,
airports, marine
Damage to infrastructure.
Chances of Floods – Develop cracks in Dams
Chances of fire short-circuit.
Communications such as telephone wires are damaged.
Water pipes, sewers are disrupted
Economic activities like agriculture, industry, trade and transport
are severely affected.
29. If you are in house;
• Don’t use lift for getting down from building.
• Be prepared to move with your family.
If you are in shop ,school or office;
• Don’t run for an exit.
•Take cover under a disk/table.
•Move away from window glass.
•Do not go near electric point and cable. Keep away from weak portion of
the building and false ceiling.
30. If you are outside;
• Avoid high buildings , walls , power lines and other objects
that could fall and create block.
• Don’t run through streets.
• If possible , move on to an open area away from hazard
including trees.
If you are in vehicle;
• Stop in a safe open place.
• Remain inside vehicle.
• Close window , doors and vents.
31. Keep calm, switch on the transistor radio and obey
instructions.
Keep away from beaches and low banks of river. A huge
wave may sweep in
Do not re enter badly damaged buildings and do not go
near damage structures.
Turn off the water, gas and electricity.
Do not smoke, light match or use a cigarette lighter
Do not turn on switches there may be gas leak or short
circuit
If there is any fire, try to put it out or call fire brigade.
32. Do not drink water from open containers without having
examined it.
If you aware of people have been buried, tell the rescue team. Do
not rush and try not to worsen the situation.
Avoid places where there are loose electric wires and do not
come in contact with any metal object.
Eat something. You will better and more capable of helping
other.
Do not walk around the streets to see what is happening. Keep
the streets clear so rescue vehicles can access the roads easily.

39. On the morning of January 26, 2001, the Nation’s
52nd Republic Day, a devastating earthquake occurred in
the Kutchh district of the state of Gujarat.
The earthquake was felt as far away as Delhi in the
north, Kolkata in the east.
Bhuj town and the village Bhachau, 60 km east of
Bhuj, were the worst affected and many other areas
of Gujarat including its state headquarters Ahmedabad,
were badly affected.
40. There were more than 20,000 deaths and 167,000 people injured
Four districts of Gujarat lay in ruin and altogether, 21 districts were
affected.
Around 300,000 families and at least 3 million children under 14
aged were affected.
Around 600,000 people were left homeless.
In the city of Bhuj, more than 3,000 Population of the city lost
their lives; the main hospital was crushed and close to 90% of the
buildings was destroyed.
There was significant damage to infrastructure with facilities such
as hospitals, schools, electric power and water systems, bridges and
roads damaged or destroyed.
42. 5 year old girl recovers

Monday after Friday's
massive earthquake.
43. The response within India was immediate. The
national and state governments quickly provided
assistance in many forms including cash, medical
supplies, communications teams, shelters, food,
clothing, transport and relief workers.
There were more than 185 non-government
organizations (NGOs), mostly Indian charities, which
undertook earthquake-related activities
44. Search and Rescue teams soon arrived from
Switzerland, United Kingdom, Russia and Turkey to
find and rescue survivors buried under debris.
Relief teams and supplies soon followed from 38
countries as well as United Nations agencies and
many international NGOs such as the Red Cross.
The world bank and Asian development bank
sanction loans in less than three months after the
earthquake.
45. Gujarat earthquake emergency reconstruction
project (GEERP) was started by GSDMA(Gujrat State
Disaster Management Authority), with financial help
from world bank, Asian development bank, govt of
India and other donor agencies.
Several state governments came forward to
participate in, the reconstruction work in different
villages.
The UN system, multilateral and bilateral agencies,
NGOs and the corporate sector participated in the
relief and reconstruction work.
46. Government of Gujarat provided assistance in the form
of materials and cash to about 218,000 families.
NGOs supplemented the efforts by providing shelter to
about 7000 families.
About 65 NGOs were active in kutch alone who
adopted 211 villages and constructed 32,297 houses at the
cost of Rs. 185.80 crores.
The technical support was made available to the
owners who were provided loan to reconstruct the
houses.
