An evaluation of the liquefaction potential for Louisville, Kentucky

A statistical regression method is used to evaluate the liquefaction potential in Jefferson County, Kentucky due to large earthquake in the New Madrid Seismic Zone. The potential is represented as a liquefaction severity index scaled to the tickness of susceptible soil layers, The method uses soil data from the existing geotechnical borehole logs and water well logs that include soil type, SPT results, depth to bedrock and water table level information. The modifying effect of the soil profile on the local bedrock acceleration is accounted for through a one dimensional, linear mode, soil response analysis (AU)
