20210304 09211200 1.0 TRUE TRUE PWB_Seismic_2016 Evaluating the potential for liquefaction and employing methods to mitigate its impacts were recognized as key factors for increasing earthquake resilience in the Oregon Resilience Plan (OSSPAC, 2013), as well as previous earthquake risk studies. Delineation of liquefaction-susceptible deposits in the PWB service area and estimating the magnitude of potential ground deformation is essential for the evaluation of potential damage from future large earthquakes in the Portland area. Mapping of liquefaction hazard allows for planning and mitigation prior to the next large earthquake and can be used for prioritizing emergency response following the earthquake.
