A system for detecting subterranean voids includes a sensor array disposed in a subterranean location, an energy emitting device disposed on a position on a surface of terrain, the energy emitting device operative to emit wave patterns that propagate in a subterranean region proximate to the energy emitting device, and a control system communicatively connected to the sensor array, the control system operative to receive signals from the sensor array indicative of the direction and intensity of wave patterns emitted from the energy emitting device and output an indication to a user indicative of the location of a subterranean void. |
