Missouri vs Wyoming Earthquake Risk

Missouri and Wyoming share the same risk score of 6/10 (Moderate-High). Both states face similar levels of seismic hazard, though the specific fault systems and earthquake characteristics differ.

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

Missouri is associated with New Madrid Seismic 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 Missouri, approximately 30% 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.

Missouri's most notable earthquake: 1811-12 New Madrid (M7.5-7.7). Wyoming's most notable earthquake: 1959 Hebgen Lake (nearby, M7.3). These historical events illustrate the seismic potential of each state.
