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.
