The week of June 15th, 2009, the S.C. Geological Survey, USC Department of Earth and Ocean Sciences, and USC Earth Science Research Institute conducted a two-mile seismic reflectivity study along Highway 27 north of Pringletown, in Berkeley County. The seismic work was to verify drilling results that showed evidence of faulting in the shallow subsurface. The shallow faulting was initially interpreted from regional geophysical data as marking the northern edge of the buried Jedburg basin. When a “thumper” is used, data collection becomes labor intensive and requires the continual movement of the thumper, geophones, and wires that send, receive, and transmit the seismic signals to the control “dog house.” Data collection also requires accurate GPS locations of the geophone stations, and the closing of the roads to minimize the interference with the signals.
