DOGAMI Earthquake Impact Analysis
The RDPO partnered with the Oregon Department of Geology and Mineral Industries (DOGAMI) to release a new study that provides information about potential impacts to Clackamas, Multnomah, and Washington counties from earthquakes, including a magnitude 9.0+ Cascadia Subduction Zone earthquake. DOGMAI did one study for Clackamas, Multnomah, and Washington Counties, follow by a second study for Columbia and Clark Counties. By using updated data, current subduction zone science, and the latest mapping and modeling techniques, the study greatly improves understanding of potential earthquake impacts for the region. The study’s estimates of injuries and fatalities, building damages, and other impacts helps communities, the region, and the state better prepare for, respond to, and recover from major earthquakes.
