3D geology and shear-wave velocity models of the Portland, Oregon, metropolitan area

In 2004, DOGAMI began collecting surface and subsurface geologic data for the Portland metropolitan area. The purpose has been to provide high-resolution and high-quality geology data to support urban earthquake hazard assessments and modeling. The final step was to create three-dimensional models of shallow geology and a shear-wave velocity model of the upper 98.4 ft of the greater Portland metropolitan area in 2012 and 2013. The purpose of building these models was to better constrain and delineate geologic hazards associated with surficial geology such as ground-shaking amplification, earthquake-induced liquefaction and lateral spread, and earthquake-induced landslides, This archived document is maintained by the Oregon State Library as part of the Oregon Documents Depository Program.
