Seattle Field Office, Seattle, WA
Earthquakes threaten the Pacific Northwest, which includes Washington, Oregon, and northern California. USGS earthquake studies of this region are intended to help reduce the losses the earthquakes may cause. Activities include collaboration with the University of Washington in contributing to the Advanced National Seismic System through operation of the Pacific Northwest Seismic Network.
In Cascadia strain arises from the interaction of three tectonic plates. The North America, Juan de Fuca, and (idirectly) the Pacific Plate all are moving with different trajectories.
The Pacific Northwest Seismic Network (PNSN) in Seattle is home to USGS and University of Washington scientist who monitor and study earthquakes in the Pacific Northwest.
