Hawaii vs Utah Earthquake Risk

Hawaii has a higher earthquake risk with a score of 8/10 (High) compared to Utah at 7/10 (High). This means Hawaii faces more frequent and potentially more destructive seismic events.

Hawaii averages approximately 500 earthquakes per year, while Utah averages about 200 per year. Hawaii experiences roughly 300 more earthquakes annually.

Hawaii is associated with Volcanic hotspot activity, Hilina slump. Utah is associated with Wasatch Fault Zone. 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 80% in Utah. Hawaii has a larger percentage of residents exposed to seismic hazard.

Hawaii's most notable earthquake: 2018 Kilauea (M6.9). Utah's most notable earthquake: 2020 Magna (M5.7). These historical events illustrate the seismic potential of each state.
