    3     If there isn’t a table or desk near you, stay in an inside corner of the building. If possible, stay away from glass, windows, outside doors and walls, and anything that could fall.

Use your hands and arms to protect these important areas from falling objects(物体). If you have any breathing disease, make sure that you cover your head with a T-shirt or something else until all the dust has settled. Dirty air is not good for you.

Remain inside until shaking stops.

Research suggests that many injuries in an earthquake happen when people inside buildings try to move to a different place inside the building or try to leave.     5     Stay where you are for a minute or two until it’s safe to go out.
