Earthquakes in Arizona

Arizona's earthquakes cluster in the north near the edge of the Colorado Plateau and in the west toward the active faults of the Basin and Range. Most are small, but the state has a genuine seismic history, and quakes along its western margin can be felt across the low desert.
