Oklahoma vs Tennessee Earthquake Risk

Oklahoma and Tennessee share the same risk score of 5/10 (Moderate). Both states face similar levels of seismic hazard, though the specific fault systems and earthquake characteristics differ.

Oklahoma averages approximately 100 earthquakes per year, while Tennessee averages about 50 per year. Oklahoma experiences roughly 50 more earthquakes annually.

Oklahoma is associated with Induced seismicity from wastewater injection. Tennessee is associated with New Madrid Seismic Zone (western TN). These fault systems determine the type and frequency of seismic activity each state experiences.

In Oklahoma, approximately 40% of the population lives in areas at risk from earthquakes, compared to 25% in Tennessee. Oklahoma has a larger percentage of residents exposed to seismic hazard.

Oklahoma's most notable earthquake: 2016 Pawnee (M5.8). Tennessee's most notable earthquake: 1811 New Madrid (felt strongly). These historical events illustrate the seismic potential of each state.
