Seismic Method - an overview | ScienceDirect Topics

Seismic methods common to hydrological investigations use high-frequency (∼100–5000 Hz) pulses of acoustic energy to probe the subsurface. These pulses are generally artificially produced (using weight drop, hammers, explosives, piezoelectric transducers, etc.) and propagate outward as a series of wavefronts.
