Earthquakes: Risk, Detection, Warning, and Research. Congressional Research Service, Library of Congress. Peter Folger. July 18, 2013.

Portions of all 50 states and the District of Columbia are vulnerable to earthquake hazards, although risks vary greatly across the country and within individual states. Seismic hazards are greatest in the western United States, particularly in California, Washington, Oregon, and Alaska and Hawaii. California has more citizens and infrastructure at risk than any other state because of the state’s frequent seismic activity combined with its large population and developed infrastructure. The United States faces the possibility of large economic losses from earthquake-damaged buildings and infrastructure. The Federal Emergency Management Agency has estimated that earthquakes cost the United States, on average, over $5 billion per year.
