[email protected] ABSTRACT The Central United States Seismic Observatory (CUSSO) consists of an array of vertical strong motion accelerometers and medium period seismometers that penetrate 585 m into the Mississippi Embayment sediments and terminate into the top of Paleozoic bedrock. The array is located near the central segment of the New Madrid Seismic Zone. The thick unlithified sediment overburden has the potential to influence earthquake ground motions; understanding how these sediments affect ground motion is the overall goal of the CUSSO array.
