California vs Kansas Earthquake Risk

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

California averages approximately 10,000 earthquakes per year, while Kansas averages about 20 per year. California experiences roughly 9,980 more earthquakes annually.

California is associated with San Andreas, Hayward, San Jacinto, Cascadia. Kansas is associated with Induced seismicity (near OK border). These fault systems determine the type and frequency of seismic activity each state experiences.

In California, approximately 98% of the population lives in areas at risk from earthquakes, compared to 5% in Kansas. California has a larger percentage of residents exposed to seismic hazard.

California's most notable earthquake: 1906 San Francisco (M7.9). Kansas's most notable earthquake: 2014 Harper County (M4.9). These historical events illustrate the seismic potential of each state.
