Tips to be better prepared:
If you are indoors when shaking starts:
- “DROP, COVER AND HOLD ON.” If you are not near a strong table or desk, drop to the floor against an interior wall and cover your head and neck with your arms.
- Avoid windows, hanging objects, mirrors, tall furniture, large appliances and cabinets filled with heavy objects.
- Do not try to run out of the structure during strong shaking.
- If you are downtown, it is safer to remain inside a building after an earthquake unless there is a fire or gas leak. There are no open areas in downtown San Francisco far enough from glass or other falling debris to be considered safe refuge sites. Glass from high-rise buildings does not always fall straight down; it can catch a wind current and travel great distances.
- If you are in bed, stay there and cover your head with a pillow.
- Do not use elevators.
- If you use a wheelchair, lock the wheels and cover your head.
If you are outdoors when shaking starts
- Move to a clear area if you can safely walk. Avoid power lines, buildings and trees.
- If you’re driving, pull to the side of the road and stop. Avoid stopping under overhead hazards
- If you are on the beach, move to higher ground. An earthquake can cause a tsunami
