How to be Prepared

Electricity, water, gas and telephone may not be working after an earthquake. The police and fire department are likely to be tied up. You should be prepared to take care of yourself for at least three days, preferably for a week.

This list can also be applied to other disasters, such as floods or wildfires.

1. food and water (a gallon a day per person)

2. a first aid kit

3. a fire extinguisher suitable for all types of fires

4. flashlights, a portable radio extra batteries

5. blankets, clothes, shoes and money (ATMs may not work)

6. baby and pet food

It’s also a good idea to decide beforehand how and where your family will reunite if separated during a quake and to conduct in-home practice drills.

During an Earthquake

If you are indoors, stay there. Get under and hold onto a desk or table, or stand against an interior wall. Stay away from exterior walls, glass, heavy furniture, and stay away from windows and outside walls and do not use the elevator.

If you are outside, get into the open, stay into the open, stay away from buildings, power lines or anything else that could fall on you.

If you are driving, move the car out of traffic and stop, avoid parking under or on bridges or overpasses, Try to get clear of trees, light posts, signs and power lines.

If you are in a crowded public place, avoid panicking and do not rush for the exit. Stay low and cover your head and neck with your hands and arms.

After an Earthquake

If the phone is working, only use it in case of emergency. Likewise, avoid driving if possible to keep the streets clear for emergency vehicles.

Be aware that items may fall out of cupboards or closets when the door is opened, and also that chimneys can be weakened and fall with touch. Check for cracks and damage to the roof and foundation of your home.

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 friends and family your location.
