Climate-Adjusted Hazard Data · Model Version 1.0
Washington faces seismic hazard from three sources: the Cascadia Subduction Zone, the Seattle Fault Zone, and deep intraslab earthquakes. The USGS NSHM 2023 assigns high seismic hazard to the Puget Sound region. The 2001 Nisqually M6.8 earthquake demonstrated vulnerability of Puget Sound infrastructure to deep intraslab events.
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.
