Oregon vs Virginia Earthquake Risk

Oregon has a higher earthquake risk with a score of 8/10 (High) compared to Virginia at 3/10 (Low-Moderate). This means Oregon faces more frequent and potentially more destructive seismic events.

Oregon averages approximately 500 earthquakes per year, while Virginia averages about 5 per year. Oregon experiences roughly 495 more earthquakes annually.

Oregon is associated with Cascadia subduction zone, Klamath graben. Virginia is associated with Central Virginia seismic zone. These fault systems determine the type and frequency of seismic activity each state experiences.

In Oregon, approximately 80% of the population lives in areas at risk from earthquakes, compared to 10% in Virginia. Oregon has a larger percentage of residents exposed to seismic hazard.

Oregon's most notable earthquake: 1993 Scotts Mills (M5.6). Virginia's most notable earthquake: 2011 Mineral (M5.8). These historical events illustrate the seismic potential of each state.
