Multi-Channel Analysis of Surface Waves (MASW) Pyramid staff have taken advantage of this relatively new technique in the recent past for the purposes of geologic mapping, identifying depth to rock, analyzing subsurface velocity and density profiles, and geotechnical investigations. We utilize the Geometrics Geode … [Read more...]
Seismic Refraction
Pyramid Geophysical Services was contracted to perform seismic refraction survey along a proposed trail in North Carolina. The seismic refraction method consists of measuring (at known points along the surface of the ground) the travel times of compression waves (P-waves) generated by an impulsive energy source. In … [Read more...]
