WebA geophone can either be a single-component geophone which is designed to record p-waves (compressional waves), or it can be a multi-component geophone designed to record p-waves and s-waves (shear waves). [13] Geophones require sufficiently strong coupling with the ground to record the true ground motion initiated by the seismic signal.
