Hawaii vs Idaho Earthquake Risk

Hawaii has a higher earthquake risk with a score of 8/10 (High) compared to Idaho at 6/10 (Moderate-High). This means Hawaii faces more frequent and potentially more destructive seismic events.

Hawaii averages approximately 500 earthquakes per year, while Idaho averages about 100 per year. Hawaii experiences roughly 400 more earthquakes annually.

Hawaii is associated with Volcanic hotspot activity, Hilina slump. Idaho is associated with Lost River, Lemhi, Beaverhead faults. These fault systems determine the type and frequency of seismic activity each state experiences.

In Hawaii, approximately 90% of the population lives in areas at risk from earthquakes, compared to 45% in Idaho. Hawaii has a larger percentage of residents exposed to seismic hazard.

Hawaii's most notable earthquake: 2018 Kilauea (M6.9). Idaho's most notable earthquake: 1983 Borah Peak (M6.9). These historical events illustrate the seismic potential of each state.
