Earthquake Hazards

Disaster Readiness and Risk Reduction

1. EARTHQUAKE HAZARDS

2. EARTHQUAKE The sensible shaking of the surface of the Earth because of the sudden release of energy in the Earth’s crust.

3. EARTHQUAKE-RELATED HAZARDS Ground Shaking Ground Rupture Liquefaction Landslide Tsunami Fire

4. GROUND RUPTURE A visible fracture and displacement of the Earth’s surface along the trace of the fault

5. LANDSLIDE A geologic hazard which includes the movement of rocks, debris, or earth down a slope

6. NATURAL HAZARDS IN THE CITY OF BACOOR Ground Shaking Tsunami Liquefaction

7. GROUND SHAKING The sideways and up and down motion felt during an earthquake

8. Ground Shaking Hazard Map

9. LIQUEFACTION The ground surface lose its strength and stiffness as a reaction to strong ground shaking

10. Liquefaction Hazard Map

11. TSUNAMI A catastrophic oceanic waves generated by the sudden displacement of seawater

12. Impending sign of a TSUNAMI Animal Behavior Drawback

15. BEFORE AN EARTHQUKE

16. GO BAG!

17. DURING AN EARTHQUKE

18. AFTER AN EARTHQUKE

19. WHEN TRAPPED Pray Check pockets or bags for anything that will help you scratch, dig, screw or signal way out Make noise Conserve energy Do not drink urine or alcohol Mobile phones: erase smileys, text instead of calling, and be concise if calling

20. STEPS IN AN EARTHQUAKE DRILL Alarm Phase Response Phase Evacuation Phase Assembly Phase Head Count Phase Evaluation Phase

21. STEPS IN AN EARTHQUAKE DRILL 1. The alarm phase Everyone should be alerted by a loud warning device, most likely the school bell. This must be a pre-arranged signal known by all so that the response will be immediate.

22. STEPS IN AN EARTHQUAKE DRILL 2. The response phase Everyone should head for cover. Make sure to move away from windows, glass or light fixtures, which pose a serious threat if it break or get loose. If there is no cover available then crouch and try to protect the head.

23. STEPS IN AN EARTHQUAKE DRILL 3. The evacuation phase When the shaking stops, everyone should then evacuate the school buildings. Proceeds through pre-determined safe routes Evacuees should gather outside in a safe area, away from buildings, trees and even poles. This safe area is called the assembly point .

24. STEPS IN AN EARTHQUAKE DRILL 4. The assembly phase At the assembly point the evacuees must be grouped in order. For example, classes are grouped together and even further grouped in alphabetical order or in order as they appear in their respective classrooms.

25. STEPS IN AN EARTHQUAKE DRILL 5. The head count phase Determine if everyone is present. A search and rescue team would have to be dispatched to look for those who are missing.

26. STEPS IN AN EARTHQUAKE DRILL 6. The evaluation Identify the snags in the drill, problem areas or potential problem areas Aim to rectify these problems for a future earthquake drill Loss to life and limb will be lessened
