PROTECT YOURSELF DURING AN EARTHQUAKE.

 DROP, COVER, AND HOLD ON.

 During an earthquake, drop to the floor, take cover under a sturdy desk or table, and hold on to it firmly. Be prepared to move with it until the shaking stops.
The area near the exterior walls of a building is the most dangerous place to be. Windows, facades and architectural details are often the first parts of the building to collapse. To stay away from this danger zone, if you are inside, stay inside, if you are outside, stay outside.
California history:
An enduring earthquake image of California is a collapsed adobe home with the door frame as the only standing part. From this came our belief that a doorway is the safest place to be during an earthquake. True—if you live in an old, unreinforced adobe house. In modern houses, doorways are no stronger than any other part of the house. You are safer under a table.
 
What to do if you are:

Indoors:
Drop, cover, and hold on. If you are near a table or desk, and can can get under it safely, then do so.  If you are not near a desk or table, drop to the floor against an interior wall and protect your head and neck with your arms.  Avoid exterior walls, windows, hanging objects, mirrors, tall furniture, large appliances, and kitchen cabinets with heavy objects or glass. Do not go outside!

In bed:
If you are in bed, hold on and stay there, protecting your head with a pillow.  You are less likely to be injured staying where you are. Broken glass on the floor has caused injury to those who have rolled to the floor or tried to get to doorways.

In a high-rise:
Drop, cover, and hold on. Avoid windows and other hazards. Do not use elevators. Do not be surprised if sprinkler systems or fire alarms activate.

Outdoors:
Move to a clear area if you can and sit down.  Avoid being near or under power lines, trees, signs, buildings, vehicles, and other hazards.
