Earthquake

An earthquake is the sudden, rapid shaking of the earth, caused by the breaking and shifting of subterranean rock as it releases strain that has accumulated over a long time.

All 50 states and 5 U.S. territories are at some risk for earthquakes.  Earthquakes can happen at any time of the year.

Before an Earthquake

  • Fasten shelves securely to walls.
  • Place large or heavy objects on lower shelves.
  • Store breakable items such as bottled foods, glass, and china in low, closed cabinets with latches.
  • Fasten heavy items such as pictures and mirrors securely to walls and away from beds, couches and anywhere people sit.
  • Locate safe spots in each room under a sturdy table or against an inside wall. Reinforce this information by moving to these places during each drill.
  • Hold earthquake drills with your family members: Drop, cover and hold on.

During

If Indoors:

  • DROP to the ground; take COVER by getting under a sturdy table or other piece of furniture; and HOLD ON until the shaking stops. If there isn’t a table or desk near you, cover your face and head with your arms and crouch in an inside corner of the building.
  • Stay away from glass, windows, outside doors and walls, and anything that could fall, such as lighting fixtures or furniture.
  • Do not use a doorway except if you know it is a strongly supported, load-bearing doorway and it is close to you. Many inside doorways are lightly constructed and do not offer protection.

If Outdoors:

  • Stay there until the shaking stops. Move away from buildings, streetlights, and utility wires. Ground movement during an earthquake is seldom the direct cause of death or injury. Most earthquake-related casualties result from collapsing walls, flying glass, and falling objects.

If in a Moving Vehicle:

  • Stop as quickly as safety permits and stay in the vehicle. Avoid stopping near or under buildings, trees, overpasses, and utility wires. Proceed cautiously once the earthquake has stopped. Avoid roads, bridges, or ramps that might have been damaged by the earthquake.

If you become trapped under debris:

  • Do not light a match.
  • Do not move about or kick up dust.
  • Cover your mouth with a handkerchief or clothing.
  • Tap on a pipe or wall so rescuers can locate you. Use a whistle if one is available. Shout only as a last resort. Shouting can cause you to inhale dangerous amounts of dust.

After

  • When the shaking stops, look around to make sure it is safe to move. Then exit the building.
  • Expect aftershocks.
  • Use the telephone only for emergency calls.
  • Stay away from damaged areas.
  • Open cabinets cautiously. Beware of objects that can fall off shelves.
  • Clean up spilled medicines, bleaches, gasoline or other flammable liquids immediately. Leave the area if you smell gas or fumes from other chemicals.
  • Inspect the entire length of chimneys for damage. Unnoticed damage could lead to a fire.

Inspect utilities:

  • If you smell gas or hear blowing or hissing noise, open a window and quickly leave the building. Turn off the gas at the outside main valve if you can and call the gas company from a neighbor's home.
  • If you see sparks or broken or frayed wires, or if you smell hot insulation, turn off the electricity at the main fuse box or circuit breaker. If you have to step in water to get to the fuse box or circuit breaker, call an electrician first for advice.
  • If you suspect sewage lines are damaged, avoid using the toilets and call a plumber. If water pipes are damaged, contact the water company and avoid using water from the tap.
