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 …
