Colorado vs Hawaii Earthquake Risk

Hawaii has a higher earthquake risk with a score of 8/10 (High) compared to Colorado at 4/10 (Moderate). This means Hawaii faces more frequent and potentially more destructive seismic events.

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

Colorado is associated with Rio Grande Rift. Hawaii is associated with Volcanic hotspot activity, Hilina slump. These fault systems determine the type and frequency of seismic activity each state experiences.

In Colorado, approximately 25% of the population lives in areas at risk from earthquakes, compared to 90% in Hawaii. Hawaii has a larger percentage of residents exposed to seismic hazard.

Colorado's most notable earthquake: 1882 Northern Colorado (M6.6). Hawaii's most notable earthquake: 2018 Kilauea (M6.9). These historical events illustrate the seismic potential of each state.
