Ground Motion Modeling

Shaking from earthquakes poses a hazard to both people and the built environment. Many factors determine how strong shaking will be in the Pacific Northwest during future earthquakes. The Ground Motion Modeling SIG seeks to advance our models of earthquake ground shaking to include state-of-the-art knowledge within field. This includes integrating information from CRESCENT’s cutting-edge research in the CVM, CFM, and DET groups, which all contribute to advancing our knowledge of the hazards posed by ground shaking. The SIG will also work closely with state and federal agencies, as well as community partners, to translate these advances into usable shaking estimates and seismic hazard models.
