Climate-Adjusted Hazard Data · Model Version 1.0
Oregon faces seismic hazard from the Cascadia Subduction Zone (CSZ), which is capable of producing M9.0+ megathrust earthquakes. USGS NSHM 2023 assigns significant seismic hazard to the Oregon coast. The Cascadia fault's last full-margin rupture occurred on January 26, 1700 (M~9.0). The USGS and geological consensus estimate a 7-15% probability of a full-margin Cascadia rupture in the next 50 years.
CivilSense computes a Climate-Adjusted Hazard Score (0–10) for earthquake hazard at any US address. The score is composed of weighted sub-components derived from federal data sources and peer-reviewed research. All score components are transparent and returned in API responses.
These are hazard scores — physical intensity likelihood only. They do not include property exposure or vulnerability data. We never call a hazard score a risk score. See the full methodology for scoring details.
