Hawaii vs Massachusetts Earthquake Risk

Hawaii has a higher earthquake risk with a score of 8/10 (High) compared to Massachusetts at 3/10 (Low-Moderate). This means Hawaii faces more frequent and potentially more destructive seismic events.

Hawaii averages approximately 500 earthquakes per year, while Massachusetts averages about 5 per year. Hawaii experiences roughly 495 more earthquakes annually.

Hawaii is associated with Volcanic hotspot activity, Hilina slump. Massachusetts is associated with Cape Ann seismic 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 10% in Massachusetts. Hawaii has a larger percentage of residents exposed to seismic hazard.

Hawaii's most notable earthquake: 2018 Kilauea (M6.9). Massachusetts's most notable earthquake: 1755 Cape Ann (M6.0). These historical events illustrate the seismic potential of each state.
