Missouri vs Oklahoma Earthquake Risk

Missouri has a higher earthquake risk with a score of 6/10 (Moderate-High) compared to Oklahoma at 5/10 (Moderate). This means Missouri faces more frequent and potentially more destructive seismic events.

Missouri averages approximately 200 earthquakes per year, while Oklahoma averages about 100 per year. Missouri experiences roughly 100 more earthquakes annually.

Missouri is associated with New Madrid Seismic Zone. Oklahoma is associated with Induced seismicity from wastewater injection. 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 40% in Oklahoma. Oklahoma has a larger percentage of residents exposed to seismic hazard.

Missouri's most notable earthquake: 1811-12 New Madrid (M7.5-7.7). Oklahoma's most notable earthquake: 2016 Pawnee (M5.8). These historical events illustrate the seismic potential of each state.
