Determining Tsunami Exposure

Although a potential tsunami-inundation zone had been delineated in Oregon, officials needed information about what was located in this area to determine what additional preparedness and response measures were needed.

The U.S. Geological Survey prepared a vulnerability assessment that compared tsunami-related risk differences among Oregon’s coastal cities. As part of the data-collection process, the team used NOAA’s coastal land cover data (C-CAP) to mine land cover information in the zoned cities and to document variations in the percentage of developed land, human populations, economic assets, and critical facilities. This report enabled representatives of the State of Oregon to further their dialogue on societal risk and response. (2016)
