Tsunami Evacuation Walk Time Maps Published

We have published tsunami evacuation walk time maps for Port Angeles, Bellingham, Anacortes, and the towns of Aberdeen, Hoquiam, and Cosmopolis. The maps show the amount of time it would take to evacuate from within the modeled inundation zone of a Cascadia-sourced subduction zone earthquake. The maps show the extent of the tsunami inundation zone […]

School Seismic Safety Webpage Update

We have published updates to our School Seismic Safety Project webpage!  The School Seismic Safety Project (SSSP) is the first phase of a statewide effort to systematically evaluate Washington school buildings for seismic performance. Many of Washington’s K–12 students attend schools that may not withstand earthquake shaking. Washington State ranks second in the nation for earthquake […]
