Kansas vs Massachusetts Earthquake Risk

Massachusetts has a higher earthquake risk with a score of 3/10 (Low-Moderate) compared to Kansas at 2/10 (Low). This means Massachusetts faces more frequent and potentially more destructive seismic events.

Kansas averages approximately 20 earthquakes per year, while Massachusetts averages about 5 per year. Kansas experiences roughly 15 more earthquakes annually.

Kansas is associated with Induced seismicity (near OK border). Massachusetts is associated with Cape Ann seismic zone. These fault systems determine the type and frequency of seismic activity each state experiences.

In Kansas, approximately 5% of the population lives in areas at risk from earthquakes, compared to 10% in Massachusetts. Massachusetts has a larger percentage of residents exposed to seismic hazard.

Kansas's most notable earthquake: 2014 Harper County (M4.9). Massachusetts's most notable earthquake: 1755 Cape Ann (M6.0). These historical events illustrate the seismic potential of each state.
