Tsunami Resources by County





Tsunami Inundation and Current Velocity Maps

The Washington Department of Natural Resources in partnership with Washington Emergency Management Division, uses tsunami modeling to produce inundation and current velocity maps of the Washington coastline. These inundation models are based on the shape of the ocean floor, the topography of the land, and the expected size and shape of tsunami waves. These properties are derived from what we know about past earthquakes and tsunamis that are found in the geologic record of the Pacific Northwest. The result of the modeling is a series of maps that show the expected depth of water and the speed of the currents from an earthquake-generated tsunami.

These are all ZIP files:


Tsunami Evacuation Maps and Brochures

Tsunami Pedestrian Evacuation Walk Maps

Tsunami evacuation walk time maps show a more detailed view of the time it would take to evacuate on foot from the tsunami inundation zone. The maps also show how long it is estimated to take for the first tsunami wave to arrive. You should use these maps to learn your routes ahead of time for home, work, and school.

Tsunami Evacuation Brochures

Tsunami evacuation brochures are single sheets providing general information about tsunami evacuation. They show tsunami inundation extent, evacuation routes, and points of interest. They also contain basic information about tsunami evacuation and preparedness, and local emergency management contacts. Some brochures are tabloid-size (11 x 17 in.). The "upside down" orientation of part of the second page is because they were designed to be folded in half and then in thirds. They can be printed on letter-size paper by telling your printer to shrink to fit or scale to 50 percent. All maps are PDFs.

NOTE: These brochures have NOT been updated as new or updated modeling and mapping have been published, nor has the contact information included in them been updated. More accurate maps may have been released since the publishing of these brochures. When using, please be sure to compare the publish date of the brochure with the publish date of other inundation and evacuation maps for the same location. If you have questions about the potential differences, please contact WA DNR.

Tsunami Hazard Fact Sheets

Similar to the Tsunami Evacuation Brochures, these Tsunami Hazard Fact Sheets provide a basic overview of the tsunami hazard at the local level.

NOTE: These fact sheets have NOT been updated as new or updated modeling and mapping have been published, nor has the contact information included in them been updated. More accurate maps may have been released since the publishing of these fact sheets. When using, please be sure to compare the publish date of the fact sheet with the publish date of inundation and evacuation maps for the same location.

All documents are PDFs.
