Futures analysis indicates 42 of the 50 states could reasonably experience an earthquake in the next 50 years.
The U.S. Geological Service recently released an update of U.S. National Seismic Hazard Maps that reflect the latest analysis of where future earthquakes will occur, how frequently they may occur, and their strength. While all states have some potential for earthquakes, 42 of the 50 states have a reasonable chance of experiencing damaging ground shaking from an earthquake in the next 50 years. Sixteen states have a relatively high likelihood of experiencing damaging ground shaking. The hazard is especially high along the West Coast, Intermountain West, and in several active regions elsewhere such as near New Madrid, Mo., and near Charleston, S.C.
