If you're outside during an earthquake, stay there and drop to the ground -- as far away as possible from any objects that could potentially fall on top of you. Most earthquake deaths and injuries aren't caused by the shaking of the earth itself; it's almost always falling debris, glass and collapsing walls that do the most damage. So make sure to stay away from exterior building walls, trees and power lines. Don't try to move until after you're sure the shaking has ceased. When you do get up, look around and be very careful of where you step. Watch for downed power lines, broken glass or other dangers in your path.
