Inundation Maps / Reports / GIS Data

When planning evacuation routes and destinations, check with local officials for guidance. In general, one should go to the least hazardous site on the map (a noncolored area or the coolest color) by the shortest route after making sure that the route is not compromised by other earthquake hazards such as liquefaction or earthquake-induced landslides. Bridges may fail in the event of an earthquake. Consult with transportation authorities about the seismic stability of bridges used for evacuation. Note that large waves continue to arrive for several hours after the initial wave.

DOGAMI Tsunami Inundation and Evacuation GIS Data via West Coast Ocean Data Portal. This data layer is an element of the Oregon GIS Framework. The evacuation zones are the local and distant tsunami scenarios shown on the tsunami evacuation brochures. These polygons represent the evacuation zones for the entire Oregon coast. All 7 tsunami scenarios, along with a text report and other supplemental files, can be found in DOGAMI Open-File Report O-13-19, Summary of Tsunami Hazard Data for Oregon (preview report).

DOGAMI Tsunami Inundation Maps (TIM series; see TIM map publication overview leaving OregonTsunami site) publications incorporate all the best tsunami science available today, including recent publications by colleagues studying the Cascadia Subduction Zone, updated computer simulation models using high-resolution lidar topographic data, and knowledge gained from the 2004 Sumatra, 2010 Chile, and 2011 Tōhoku earthquakes and tsunamis.
