What to do in an earthquake

Drop
Drop where you are onto hands and knees.

Cover
Cover your head and neck with one arm and hand. If a sturdy table or desk is nearby, crawl underneath it for shelter. If no shelter is nearby, crawl next to an interior wall (away from windows). Stay on your knees; bend over to protect vital organs.

Hold On
Hold until the shaking stops. If under shelter, hold on with one hand and be ready to move with it when the shelter moves. If not under shelter, hold on to your head and neck with both arms and hands.
