When it shakes

What to do in an earthquake

  1. 1

    Drop

    Drop where you are onto hands and knees.

  2. 2

    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.

  3. 3

    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.

Wilmington: the state’s most populous city in the Census Vintage 2024 estimates. Older years hold fewer small quakes because fewer instruments were listening.
