Colorado vs Missouri Earthquake Risk

Missouri has a higher earthquake risk with a score of 6/10 (Moderate-High) compared to Colorado at 4/10 (Moderate). This means Missouri faces more frequent and potentially more destructive seismic events.

Colorado averages approximately 50 earthquakes per year, while Missouri averages about 200 per year. Missouri experiences roughly 150 more earthquakes annually.

Colorado is associated with Rio Grande Rift. Missouri is associated with New Madrid Seismic Zone. 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 30% in Missouri. Missouri has a larger percentage of residents exposed to seismic hazard.

Colorado's most notable earthquake: 1882 Northern Colorado (M6.6). Missouri's most notable earthquake: 1811-12 New Madrid (M7.5-7.7). These historical events illustrate the seismic potential of each state.
