Close to 75 million people in 39 states face some risk from earthquakes. Seismic hazards are greatest in the western United States, particularly California, Alaska, Washington, Oregon, and Hawaii. The Rocky Mountain region, a portion of the central United States known as the New Madrid Seismic Zone, and portions of the eastern seaboard, particularly South Carolina, also have a relatively high earthquake hazard. Compared to the loss of life in other countries, relatively few Americans have died as a result of earthquakes over the past 100 years. The United States, however, faces the possibility of large economic losses from earthquakedamaged buildings and infrastructure.
