Hawaii vs Oregon Earthquake Risk

Hawaii and Oregon share the same risk score of 8/10 (High). Both states face similar levels of seismic hazard, though the specific fault systems and earthquake characteristics differ.

Hawaii averages approximately 500 earthquakes per year, while Oregon averages about 500 per year. Oregon experiences roughly 0 more earthquakes annually.

Hawaii is associated with Volcanic hotspot activity, Hilina slump. Oregon is associated with Cascadia subduction zone, Klamath graben. These fault systems determine the type and frequency of seismic activity each state experiences.

In Hawaii, approximately 90% of the population lives in areas at risk from earthquakes, compared to 80% in Oregon. Hawaii has a larger percentage of residents exposed to seismic hazard.

Hawaii's most notable earthquake: 2018 Kilauea (M6.9). Oregon's most notable earthquake: 1993 Scotts Mills (M5.6). These historical events illustrate the seismic potential of each state.
