Kansas vs Oklahoma Earthquake Risk

Oklahoma has a higher earthquake risk with a score of 5/10 (Moderate) compared to Kansas at 2/10 (Low). This means Oklahoma faces more frequent and potentially more destructive seismic events.

Kansas averages approximately 20 earthquakes per year, while Oklahoma averages about 100 per year. Oklahoma experiences roughly 80 more earthquakes annually.

Kansas is associated with Induced seismicity (near OK border). Oklahoma is associated with Induced seismicity from wastewater injection. 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 40% in Oklahoma. Oklahoma has a larger percentage of residents exposed to seismic hazard.

Kansas's most notable earthquake: 2014 Harper County (M4.9). Oklahoma's most notable earthquake: 2016 Pawnee (M5.8). These historical events illustrate the seismic potential of each state.
