Here are some other earthquake preparedness techniques that L.A. County officials and the USGS have outlined:

Before an earthquake

  • Identify potential hazards in your home and begin to fix them.
  • Create a disaster preparedness plan.
  • Identify your building’s potential weaknesses and begin to fix them.

During an earthquake

  • If you are indoors, stay there! Get under a desk or table and hold on to it (Remember: DROP, COVER AND HOLD ON). Stay clear of fireplaces, windows and appliances. Get out of the kitchen. Do not run downstairs or go outside because there could be a danger of items falling on you.
  • If you are outdoors, get away from buildings, chimneys, power lines and stay in the open.
  • If you are driving, carefully come to a stop and stay inside your car until shaking stops. Move far away from traffic. Do not stop under a bridge, overpass, trees, light posts, powerlines or anything that could fall on you. When the shaking stops, look out for debris on the road, broken pavement and bumps in the road.
  • If you are in a mountainous area, be on the lookout for debris, such as trees, rocks or any other things in the environment that an earthquake can loosen.
  • If you are near the ocean, see these safety rules from NOAA’s Tsunami Warning Center.
