     Do you know how to prepare for and survive a major earthquake? According to Department of

Conservation scientists, it is important to have the right answer to that question.

     How to Be Prepared

     Electricity, water, gas and telephones may not be working after an earthquake. The police and fire

departments are likely to be tied up. You should be prepared to fend for yourself for at least three days,

preferably for a week. You'll need food, water and so on. It's also a good idea to decide ahead of time

how and where your family will reunite if separated during a quake. You might choose an out-of-the-area

friend or relative that family members can call to check on you.

     _____

     If you're indoors, stay there. Get under a desk or table. The kitchen is a particularly dangerous spot.

If you're in an office building, stay away from windows and outside walls and do not use the elevator.

If you're outside, get into the open. Stay clear of buildings, power lines or anything else that could fall

on you. If you're driving, move the car out of traffic and stop. Avoid parking under or on bridges or

overpasses.

     After an Earthquake

     Check for fire. If you smell gas, shut off the main gas valve (阀). If there's sign of damage to

electrical wiring, shut off the power at the control box. If the phone is working, only use it in case of

emergency. Avoid driving if possible to keep the streets clear for emergency vehicles. Be careful that

things may fall out of cupboards when the door is opened, and also that chimneys can be weakened

and fall with just a touch. Listen to the radio for important information and instructions. Remember that

aftershocks, sometimes large enough to cause damage in their own right, generally follow large quakes.

If you leave home, leave a message telling your friends and family your location.
