    Frequently asked questions

    Which US states have the highest earthquake risk?

    California, Alaska, Washington, Oregon, Nevada, and parts of Utah have the highest earthquake hazard. Notably, the New Madrid Seismic Zone (Missouri, Tennessee, Arkansas) and the Eastern Tennessee Seismic Zone also produce significant earthquake risk in regions many don't expect.

    How much warning do I get before an earthquake?

    For most areas, none. USGS ShakeAlert provides seconds-to-tens-of-seconds of warning in California, Oregon, and Washington via Android, iPhone, or opt-in apps. Otherwise, the first indication is shaking itself — Drop, Cover, Hold On immediately.

    Do I need earthquake insurance?

    Earthquake damage is not covered by standard homeowners policies. In high-risk states, a separate earthquake policy or rider is essential. Cost varies significantly by zip code and construction type.
