South Carolina vs Wyoming Earthquake Risk

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

South Carolina averages approximately 15 earthquakes per year, while Wyoming averages about 2,000 per year. Wyoming experiences roughly 1,985 more earthquakes annually.

South Carolina is associated with Middleton Place-Summerville 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 South Carolina, 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.

South Carolina's most notable earthquake: 1886 Charleston (M7.3). Wyoming's most notable earthquake: 1959 Hebgen Lake (nearby, M7.3). These historical events illustrate the seismic potential of each state.
