With the release of tsunami inundation maps for Arch Cape - Falcon Cove, Cape Lookout, Sand Lake, Pacific City, Nestucca Bay, and Neskowin, the Oregon Department of Geology and Mineral Industries has now mapped the entire coastline of Tillamook County to show modeled extents for local-source (Cascadia Subduction Zone) and distant-source (Alaska) tsunami inundation scenarios.

These maps 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 Tohoku earthquakes and tsunamis.

The maps provide a wealth of information, including estimated tsunami wave height time series charts and a measurement of the exposure each community has to the various tsunami scenarios: we count the number of buildings that are inundated by each scenario. We hope 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.
