Utah vs Wyoming Earthquake Risk

Utah has a higher earthquake risk with a score of 7/10 (High) compared to Wyoming at 6/10 (Moderate-High). This means Utah faces more frequent and potentially more destructive seismic events.

Utah averages approximately 200 earthquakes per year, while Wyoming averages about 2,000 per year. Wyoming experiences roughly 1,800 more earthquakes annually.

Utah is associated with Wasatch Fault Zone. Wyoming is associated with Teton Fault, Yellowstone volcanic zone. These fault systems determine the type and frequency of seismic activity each state experiences.

In Utah, approximately 80% of the population lives in areas at risk from earthquakes, compared to 40% in Wyoming. Utah has a larger percentage of residents exposed to seismic hazard.

Utah's most notable earthquake: 2020 Magna (M5.7). Wyoming's most notable earthquake: 1959 Hebgen Lake (nearby, M7.3). These historical events illustrate the seismic potential of each state.
