An earthquake is a sudden, rapid shaking of the earth caused by the breaking and shifting of rock beneath the earth’s surface. Earthquakes strike suddenly, without warning, and they can occur at any time of the year, day or night. Forty-five states and territories in the United States are at moderate to very high risk of earthquakes, and they are located in every region of the country. Learn how to prepare for an earthquake with the following safety tips provided by the American Red Cross.

Are You at Increased Risk from Earthquakes?

Contact your local emergency management office, local American Red Cross, state geological survey or department of natural resources for specific information about your community’s risk. However, bear in mind:

  • Mobile homes and homes not attached to their foundations are at particular risk during an earthquake.
  • Buildings with foundations resting on landfill and other unstable soils are at increased risk of damage.
