Arkansas vs Wyoming Earthquake Risk

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

Arkansas averages approximately 40 earthquakes per year, while Wyoming averages about 2,000 per year. Wyoming experiences roughly 1,960 more earthquakes annually.

Arkansas is associated with New Madrid Seismic Zone (NE corner). Wyoming is associated with Teton Fault, Yellowstone volcanic zone. These fault systems determine the type and frequency of seismic activity each state experiences.

In Arkansas, approximately 20% 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.

Arkansas's most notable earthquake: 1811 New Madrid (epicenter nearby). Wyoming's most notable earthquake: 1959 Hebgen Lake (nearby, M7.3). These historical events illustrate the seismic potential of each state.
