How to mitigate and manage the risks from Earthquake?

RISK MANAGEMENT

PROTECTION

Preparing for an Earthquake

Knowledge and Research

1. Become familiar with earthquake terms.• Aftershocks• Epicenter• Fault• Focus• Intensity• Magnitude• Mercalli Scale• Tidal wave• Tsunami

2. Safeguard your home by:• Bolting bookshelves, water heaters and cabinets to wall studs.• Anchoring things so that they will not move or fall during an earthquake.

Preparing for an Earthquake

Protection

During Earthquake1. Get under a heavy table or desk and hold on,

or sit or stand against an inside wall.2. Keep away from windows.3. Many injuries occur when people act on their

impulse to run.4. Train yourself to take cover where ever you are.

Responses Inside Buildings during an Earthquake1. Drop, cover, and hold on.2. Get under a table.3. Do not stand in a doorway. Buildings today have so much partitioning, much of which is temporary, that many doorways are actually weak points. 4. If you have nothing to get under, sit down against an interiorwall or next to a chair, holding on if possible.5. If children are in another room, take cover in the closest safe place and call to them to do the same.

Responses If You Are Outside during an Earthquake

1. Outside, get away from buildings, walls, trees and power lines.• If you cannot get clear of hazards, getting back inside a building is better than staying on the sidewalk.• Sidewalks next to buildings are among the worst places to be.

2. In a car, ease off the accelerator and slow down carefully. Do not stop on or under overpasses and bridges if you can avoid them. Be aware of what traffic around you is doing and act accordingly.3. If you live in coastal areas, be aware of possible tsunamis.

Responses After Earthquake

In addition to the basic precautions undertaken after the earthquake you should:1. Expect aftershocks.2. Avoid using vehicles except in emergencies.3. Check yourself for injuries and protect yourself by

putting on shoes, work gloves and any other protective gear at hand.

4. If the electricity is off, turn on a flashlight5. Once you are sure that you're all right, check the

people around you for injuries.• You might ask loudly, "Is everyone okay?" This will

also help calm people.• The types of injuries that happen most often in an

earthquake include cuts, bruises, fractures and physiological shock.
