Idaho vs Oklahoma Earthquake Risk

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

Idaho averages approximately 100 earthquakes per year, while Oklahoma averages about 100 per year. Oklahoma experiences roughly 0 more earthquakes annually.

Idaho is associated with Lost River, Lemhi, Beaverhead faults. Oklahoma is associated with Induced seismicity from wastewater injection. These fault systems determine the type and frequency of seismic activity each state experiences.

In Idaho, approximately 45% of the population lives in areas at risk from earthquakes, compared to 40% in Oklahoma. Idaho has a larger percentage of residents exposed to seismic hazard.

Idaho's most notable earthquake: 1983 Borah Peak (M6.9). Oklahoma's most notable earthquake: 2016 Pawnee (M5.8). These historical events illustrate the seismic potential of each state.
