The Oregon Tsunami

Click on the "Visible layers" box below to view high water marks expected in two types of tsunamis. A "SM," or small tsunami, simulates what would happen in an 8.7 magnitude quake that raises the ocean floor about 9 feet. An "XXL," or extra-extra large tsunami, represents a wave caused by a 9.1 magnitude earthquake that raises the ocean floor about 33 feet. The map, using data from Oregon's Department of Geology and Mineral Industries, shows locations of schools, hospitals, fire stations and other "critical resources" in red. Evacuation centers are in purple.
