Earthquake Hazard Areas (U.S.)

North AmericaPhysical Environment

Areas in the United States with greater than 1% probability of potentially damaging ground shaking in one year

A map highlights earthquake hazard areas across the United States using a color-coded scheme to indicate different levels of hazard.

The lowest hazard areas are shaded in blue, covering parts of Texas, Florida, Iowa, North Dakota, and Wisconsin, as well as extreme northern regions of Alaska. Low hazard areas are shaded in purple, seen in regions such as parts of the eastern and middle United States, including Dallas, Chicago, and Washington D.C. Moderately low hazard areas are shaded in pink, found in central and northern Illinois, and spread across western parts including Oregon, Arizona, and New Mexico. Moderate hazard areas are shaded in orange, covering parts of the eastern and western regions, and most of Alaska. Moderately high hazard areas are shaded in yellow, covering regions such as the West Coast, including California, Oregon, and Washington, as well as Fairbanks in Alaska. High hazard areas are shaded in light brown, seen in parts of Anchorage and the western coastal regions. The highest hazard areas are shaded in dark brown, notably in regions like southern Alaska and parts of California, including the San Francisco and Los Angeles areas.
