What is a geophone?

A geophone is a small sensor used to measure seismic activity by converting soil movement to a voltage.

How does a geophone work?

The device consists of a seismic mass that hangs from a set of springs. The mass contains a magnet and wrapped by a coil in a static way. Ground motions at frequencies less than the resonance frequency cause the suspended mass to also move. The movement of the mass causes the magnetic field to produce the electrical voltage proportional to the vibratory level.

The geophones can have scientific and industrial application. The device is widely used by seismologists and geologists to detect seismic activity, predict earthquakes, analyze the movements of tectonic plates and study the soil. The geophones are also used by the oil, gas, mining and security companies.
