Kansas vs Pennsylvania Earthquake Risk

Kansas and Pennsylvania share the same risk score of 2/10 (Low). Both states face similar levels of seismic hazard, though the specific fault systems and earthquake characteristics differ.

Kansas averages approximately 20 earthquakes per year, while Pennsylvania averages about 3 per year. Kansas experiences roughly 17 more earthquakes annually.

Kansas is associated with Induced seismicity (near OK border). Pennsylvania is associated with Minor intraplate zones. 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 3% in Pennsylvania. Kansas has a larger percentage of residents exposed to seismic hazard.

Kansas's most notable earthquake: 2014 Harper County (M4.9). Pennsylvania's most notable earthquake: 1994 Reading (M4.6). These historical events illustrate the seismic potential of each state.
