Puerto Rico vs Wyoming Earthquake Risk

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

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

Puerto Rico is associated with Puerto Rico Trench, Mona Passage. Wyoming is associated with Teton Fault, Yellowstone volcanic zone. These fault systems determine the type and frequency of seismic activity each state experiences.

In Puerto Rico, approximately 95% of the population lives in areas at risk from earthquakes, compared to 40% in Wyoming. Puerto Rico has a larger percentage of residents exposed to seismic hazard.

Puerto Rico's most notable earthquake: 2020 Guayanilla (M6.4). Wyoming's most notable earthquake: 1959 Hebgen Lake (nearby, M7.3). These historical events illustrate the seismic potential of each state.
