Service Description: The mission of the Washington Geological Survey (WGS) is to collect, develop, use, distribute, and preserve geologic information to promote the safety, health, and welfare of the citizens, protect the environment, and support the economy of Washington. In order to do this, WGS works with the National Oceanic and Atmospheric Administration (NOAA) and the University of Washington to model the inundation (flooding) of coastal areas from tsunamis. From these models the WGS produces tsunami inundation maps to communicate the hazard identified in these models to emergency management, planners, and the public to prepare for the next event in Washington. The WGS works with the Washington Emergency Management Division and local, county, tribal, and other planners and emergency managers to develop, publish, and distribute pedestrian evacuation maps, and evacuation brochures. These maps and brochures are made for areas that are especially at risk for damaging tsunamis.
This feature class contains polygons for areas in which tsunami inundaton and evacuation publications were generated. The source publications for these data are provided as hyperlinks within this feature class.
