Seismometer are used by seismologists to measure and record seismic waves.
By studying seismic waves, geologists can map the interior of the Earth, and measure and locate earthquakes and other ground motions.
The term seismograph is usually interchangeable, but seismometer seems to be a more common usage.
Seismic wave.
A seismic wave is a wave that travels through the Earth, most often as the result of a tectonic earthquake, sometimes from an explosion.There are two types of seismic wave, namely, 'body wave' and 'surface wave'.
There are two kinds of body waves: primary (P-waves) and secondary (S-waves).
Surface waves are analogous to water waves and travel just under the Earth's surface.
They travel more slowly than body waves.
