An example of seismic data showing arrival waves (marked by blue crosses) and shear wave velocities every 5ft

Seismic data is useful to liquefaction studies and interpreting soil density from wave velocity. Our rigs are equipped with a sledgehammer and strike plate wired to an onboard computer, making it simple to record compression and shear waves at any interval. The standard interval of 5ft produces a high enough resolution for most studies.
