Seismic waves reflect and refract off subsurface rock formations and travel back to acoustic receivers called geophones (on land) or hydrophones (in water).

Like any of the seismograph techniques, you set sensitive listening devices, called geophones, in the surface of the ground, and they record the echoes of loud noises, made on or near the surface, as they bounce off the different geological structures below.

The station we built beside the glacier holds three sensors called geophones, which measure the movement of the rock bed along different axes (north/ south, east/ west, up/ down).
