Hawaii vs Tennessee Earthquake Risk

Hawaii has a higher earthquake risk with a score of 8/10 (High) compared to Tennessee at 5/10 (Moderate). This means Hawaii faces more frequent and potentially more destructive seismic events.

Hawaii averages approximately 500 earthquakes per year, while Tennessee averages about 50 per year. Hawaii experiences roughly 450 more earthquakes annually.

Hawaii is associated with Volcanic hotspot activity, Hilina slump. Tennessee is associated with New Madrid Seismic Zone (western TN). 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 25% in Tennessee. Hawaii has a larger percentage of residents exposed to seismic hazard.

Hawaii's most notable earthquake: 2018 Kilauea (M6.9). Tennessee's most notable earthquake: 1811 New Madrid (felt strongly). These historical events illustrate the seismic potential of each state.
