Energy waves generated by an earthquake or an artificial explosion
Definition
Waves consist of a disturbance in materials (media) that carries energy and propagates. However, the material that the wave propagates in generally does not move with the wave. The movement of the material is generally confined to small motions, called particle motion, of the material as the wave passes. After the wave has passed, the material usually looks just like it did before the wave, and, is in the same location as before the wave. When stress builds up in the Earth to such a level that rapid slip occurs on a fracture (i.e., an earthquake takes place) or when an explosion or mechanical device is used to initiate a seismic disturbance artificially, a complex field of seismic waves is generated. This wave field propagates much like the waves that travel away from the point at which a stone is thrown into a pond. Waves that travel through the interior of the Earth are called body waves.
