Frequently Asked Questions

What is the definition of geophone?

Science definitions for geophone. An electronic receiver designed to pick up seismic vibrations on or below the Earth's surface and to convert them into electric impulses that are proportional to the displacement, velocity, and acceleration of ground movement.

How does a geophone work?

Unsourced material may be challenged and removed. 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 voltage from the base line is called the seismic response and is analyzed for structure of the earth.

What is the difference between MEMS and geophones?

MEMS have a much higher noise level (50 dB velocity higher) than geophones and can only be used in strong motion or active seismic applications. The frequency response of a geophone is that of a harmonic oscillator, fully determined by corner frequency (typically around 10 Hz) and damping (typically 0.707).

How are geophones used in geology?

In analog devices, three moving coil elements are mounted in an orthogonal arrangement within a single case. The majority of geophones are used in reflection seismology to record the energy waves reflected by the subsurface geology. In this case the primary interest is in the vertical motion of the Earth's surface.
