The vulnerability of selected components of the Memphis Water System is evaluated herein for a 7.5 moment magnitude earthquake within the southern portion of the New Madrid Seismic Zone. Pump stations, and the buried transmission and distribution piping are the system components considered. For the above ground pump station, ground shaking is the seismic hazard of interest. For the buried piping, both seismic wave propagation and permanent ground deformation (PGD) due to liquefaction and subsequent lateral spreading are the seismic hazards of interest.
