An updated small-strain shear wave velocity (Vs) model of near-surface sediments is constructed using measurements from over 90 investigation sites in the greater Charleston area. It is constructed by separating the Vs measurements into six major geologic units. The six units are: 1) man-made fills, 2) Holocene and late Pleistocene deposits, 3) the Wando Formation, 4) the Ten Mile Hill beds, 5) the Penholoway Formation and the Daniel Island beds, and 6) Tertiary deposits. Median Vs values for these units in the top 25 m are 145 m/s, 111 m/s, 189 m/s, 176 m/s, 285 m/s and 399 m/s, respectively. …
