Seismometer - Wikipedia

A seismometer is an instrument that measures motion of the ground, caused by, for example, an earthquake, a volcanic eruption, or the use of explosives. Records of seismic waves allow seismologists to map the interior of the Earth and to locate and measure the size of events like these.

IRIS Seismographs in Schools - Seismometers

A seismometer is a very sensitive instrument that can detect movements of the Earth's surface. The surface is in constant motion due to natural and man-made phenomena. For example, the solid Earth tide is the stretching of the Earth due to the gravitational pull of the moon. Phoenix, Arizona slowly rises and falls twice a...

How Does a Seismometer Work? - IRIS

A seismograph is a device for measuring the movement of the earth, and consists of a ground- motion detection sensor, called a seismometer, coupled with a recording system. A simple seis- mometer that is sensitive to up-down motions of the earth can be understood by visualizing a weight hanging on a spring. The spring...

Seismographs - Earthquake Glossary

seismograph. A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage.

Waves, Seismometers, and Seismograms

The range of ground motion amplitudes that are of interest in earthquake studies is very large and seismometers we use are very sensitive. They can detect motions that are much smaller than the thickness of a sheet of paper or as tall as a room. We can detect ground motion in Missouri caused by increased surf activity as a...
