This document summarizes the four main types of earthquakes: tectonic, volcanic, collapse, and explosion. Tectonic earthquakes are caused by the movement of tectonic plates and can trigger tsunamis and landslides. Volcanic earthquakes occur due to movement of magma underground or during volcanic eruptions. Collapse earthquakes happen when structures fail, often due to poor construction or weather. Explosion earthquakes result from detonations. The 1976 Moro Gulf earthquake in the Philippines, which measured 8.0 and caused a destructive tsunami, is also described. The document provides tips for earthquake preparedness, including having an emergency plan and supplies, and advice for dropping, covering,

3. Tectonic Earthquake
Tectonic Earthquakes are
caused by the movement
of the Earth's plates.

4. Cause
Tectonic earthquake occur when the
Earth's plates move. This can happen
when one plate slides underneath
another.

5. Effects
Tectonic earthquakes are
incredibly powerful and can cause
extensive damage. They can also
trigger other natural disasters,
such as tsumis and landslides

6. Volcanic Earthquake
Volcanic Earthquake are
caused by the movement
of the magma beneath
the Earth's surface.

7. Cause
This can happen when the magma
is forced up by the movement of
magma beneath the Earth's surface
or when it's released from a volcano.

8. Effects
Volcanic earthquakes can cause
significant damage, even though they
are typically smaller than tectonic
earthquake. They can also trigger other
natural disasters such as tsunamis
and landslides.

9. Collapse Earthquake
Collapse Earthquake
occur when buildings or
other structures collapse.

10. Causes
•Poor construction
•Severe weather
•An Earthquake

11. Effects
•Fires
•Gas Leaks

12. Explotion Earthquake
Explotion Earthquakes are
caused by the detonation
of explosive.

13. Causes
•Construction
•Mining
•Warfare

14. Effects
•Fires
•Gas Leaks

15. Moro Gulf
The 1976 Moro Gulf earthquake and tsunami occurred on August
17, 1976, at 00:11 local time near the islands of Mindanao and Sulu,
in the Philippines. It measured 8.0 on the moment magnitude
scale occurring at a depth of 20 km. The earthquake was
accompanied by a destructive tsunami that resulted in a majority
of the estimated 5,000 to 8,000 fatalities

Secure heavy
furniture and
appliances
Identify safe
spots
04
03 Have a plan
Gather supplies

18. During an Earthquake
Indoors – Get under a desk or table, cover your head
and neck with one arm or hand, and use your other
arm or hand to hang on (drop, cover, and hold on)
Outdoors – Quickly find an open space away
from buildings, power lines, and anything else
that can topple on you.

19. After an Earthquake
•Conduct a safety check
•Get help, if needed
•Be prepared for aftershocks
•Stay connected
