DOGAMI Earthquake Regional Impact Analysis - Phase 2

The DOGAMI Earthquake Regional Impact Analysis project is being done in two phases. Phase 1 focused on Multnomah, Washington, and Clackamas Counties. It was initiated in 2016 and released in March 2018. Phase 2 expands the study to Columbia and Clark counties. It will begin in 2018. 

By using updated data, current subduction zone science, and the latest mapping and modelling 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.
