DMCS has successfully completed her
social power point presentation on
earthquake.

3. AKNOWLEDGEMENT
I wish to express my sincere gratitude to my social
teacher Mrs. AYESHA SIDDIQHA for providing me
an opportunity to do my project work on earthquakes.
I sincerely thank all the websites which had provided
me information for this project. Last but not the least
I wish to avail myself this opportunity to express my

5. An earthquake is a shaking of the ground caused by the
sudden breaking and movement of large sections (tectonic
plates) of the earth's rocky outermost crust. The edges of
the tectonic plates are marked by faults (or fractures). Most
earthquakes occur along the fault lines when the plates
slide past each other or collide against each other.

6. Causes of earthquakes
There are two main causes
of earthquakes.
Firstly, they can be linked to
explosive volcanic eruptions;
they are in fact very common in
areas of volcanic activity where
they either proceed or
accompany eruptions.
Secondly, they can be triggered
by Tectonic activity associated
with plate margins and faults.
The majority of earthquakes
world wide are of this type.

7. Preventions
Before the earthquake:
Prepare a disaster preparedness kit.
Have an emergency evacuation plan.
Anchor heavy objects and potential falling
hazards. (bookcases, wall units, mirrors,
cabinets, etc.)
Know emergency telephone numbers.

8. During an earthquake:
Stay calm………
If inside: stand in a doorway or crouch
beside a desk or table. hold on, don’t let
the table slide or the door swing and hit
you
If outside: stand away from buildings,
trees, telephone, and electrical lines.
If on the road: drive away from
underpasses and overpasses; stop in a safe
area, stay in between vehicles or between
sturdy furniture.

9. After an earthquake:
Check for injuries and provide first aid.
Do a safety check: check for gas, water,
downed power lines and shortages. Turn off
appropriate utilities; Check for damage.
Turn on the radio and listen for instructions
on safety or recovery actions.
Use the telephone for emergencies only.

15. You cannot stop earthquakes, but we can learn more, in hopes of discovering
ways to protect ourselves from them. There are a few ways we could help
prevent some damage of earthquakes in the future. Many buildings are
constructed in areas of earthquake risk. If a building is being constructed in a
city that has experienced earthquakes, new plans and building materials should
be used to strengthen the building. Recently, materials like this have been
invented, such as a combination of steel and rubber plates on buildings to absorb
the shock of the earthquake. Another easy safety thing for earthquakes is for the
government of a city to INVEST in a proper seismograph centre, and make sure
there is always at least one person monitoring it in case of an earthquake.
Simple precautions are the most effective way to minimize earthquake damage.
so let us hope that no human life will be wasted for the cause of an
earthquake………………………………………..
