NDT uses vertical seismic profiling (VSP) compressional and shear wave measurements to determine the compressional and shear wave velocity of soil and bedrock using a single receiver borehole and surface energy locations. We position sensors in the borehole and seismic energy is generated at multiple surface locations independently to generate multiple wave paths to each sensor.
