Explore: Geophone

A geophone is a device that converts ground movement (velocity) into voltage, which may be recorded at a recording station. The deviation of this measured

at specified locations on the surface by what are known as receivers (geophones or hydrophones). Before seismic data can be acquired, a seismic survey

two geophones were then placed in a sequence running perpendicular to geophones 1 and 2, creating a triangle with three geophones with one geophone located

Located near the town of Parkfield, California, the project installed geophone sensors and GPS clocks in a borehole that cut directly through the fault
