Oklahoma vs Wyoming Earthquake Risk

Wyoming has a higher earthquake risk with a score of 6/10 (Moderate-High) compared to Oklahoma at 5/10 (Moderate). This means Wyoming faces more frequent and potentially more destructive seismic events.

Oklahoma averages approximately 100 earthquakes per year, while Wyoming averages about 2,000 per year. Wyoming experiences roughly 1,900 more earthquakes annually.

Oklahoma is associated with Induced seismicity from wastewater injection. Wyoming is associated with Teton Fault, Yellowstone volcanic zone. These fault systems determine the type and frequency of seismic activity each state experiences.

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

Oklahoma's most notable earthquake: 2016 Pawnee (M5.8). Wyoming's most notable earthquake: 1959 Hebgen Lake (nearby, M7.3). These historical events illustrate the seismic potential of each state.
