Missouri vs Ohio Earthquake Risk

Missouri has a higher earthquake risk with a score of 6/10 (Moderate-High) compared to Ohio at 2/10 (Low). This means Missouri faces more frequent and potentially more destructive seismic events.

Missouri averages approximately 200 earthquakes per year, while Ohio averages about 5 per year. Missouri experiences roughly 195 more earthquakes annually.

Missouri is associated with New Madrid Seismic Zone. Ohio is associated with Anna Seismic Zone, induced seismicity. These fault systems determine the type and frequency of seismic activity each state experiences.

In Missouri, approximately 30% of the population lives in areas at risk from earthquakes, compared to 5% in Ohio. Missouri has a larger percentage of residents exposed to seismic hazard.

Missouri's most notable earthquake: 1811-12 New Madrid (M7.5-7.7). Ohio's most notable earthquake: 1986 Perry (M5.0). These historical events illustrate the seismic potential of each state.
