Seattle urban seismic hazard map
WebRecently, the California Geological Survey (CGS) has produced seismic hazard zone maps that delineate areas that are likely to contain liquefiable sediments in seismically active areas of the state. The CGS zonation is based on susceptibility evaluations that use geologic criteria and borehole analyses similar to the method used in this study. WebThe increases are due primarily to two factors: 1) sig-nificant growth in urban areas that are prone to earthquakes; and 2) ...
