Shear-Wave and Compression-Wave Active Seismic at the Callahan Mine Superfund Site in Brooksville, Maine: October 2016 to July 2018

On May 10, 2017 a land-based seismic survey was collected to obtain a shear- wave velocity (Vs) and compressional velocity (Vp). The Vs was used for estimating with the HVSR data to determine the depth to rock. A secondary objective was to obtain Vs and Vp measurements of the overburden sediments at the toe of the impoundment and adjacent to the stream for geotechnical applications. Four collections were made with a 34.5-m long array of 48 electrodes with one vertical and one horizontal phone every 1.5 m along the survey line. A hammer and two strike plates were used to generate the compressional and shear-wave sound sources.
