DOGAMI has also The Oregon Department of Geology and Mineral Industries incorporated physical evidence that suggests that portions of the 200 (DOGAMI) has been identifying and mapping the tsunami inundation coast may drop 4 to 10 feet during the earthquake; this effect is hazard along the Oregon coast since 1994. In Oregon, DOGAMI known as subsidence. Detailed information on fault geometries, 100 manages the National Tsunami Hazard Mitigation Program, which subsidence, computer models, and the methodology used to create has been administered by the National Oceanic and Atmospheric the tsunami scenarios presented on this map can be found in Administration (NOAA) since 1995. DOGAMI’s work is designed to DOGAMI Special Papers 41 (Priest and others, 2009) and 43 (Witter help cities, counties, and other sites in coastal areas reduce the and others, 2011). potential for disastrous tsunami-related consequences by understanding and mitigating this geologic hazard. Using federal Map Explanation funding awarded by NOAA, DOGAMI has developed a new generation of tsunami inundation maps to help residents and visitors along the This tsunami inundation map displays the output of computer entire Oregon coast prepare for the next Cascadia Subduction Zone models representing five selected tsunami scenarios, all of which (CSZ) earthquake and tsunami.
