New Tsunami Inundation Maps Available

The Oregon Department of Geology and Mineral Industries has completed tsunami inundation maps for Florence, Dunes City, Reedsport, Gardiner, Winchester Bay, and surrounding areas. These maps show modeled extents for the Cascadia Subduction Zone and Alaskan tsunami inundation scenarios. The maps incorporate all the latest tsunami science available, including recent publications 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 Tohoku earthquakes and tsunamis.

The maps, which provide the basis for the evacuation brochures, contain information, including estimated tsunami wave height time series charts and a measurement of the exposure each community has to the various tsunami scenarios: counting the number of buildings that are inundated by each scenario. The ODGMI hopes that the public, planners, emergency managers and first responders, elected officials, and other local decision makers will use these detailed and innovative TIM map products to mitigate risk and to reduce the loss of life and property.
