Introduction. Earthquake waves are seismic waves that are created when energy builds up in rocks and they fracture. Scientists estimate there are several million earthquakes each year. Every earthquake produces P waves and S waves but only larger earthquakes produce Love waves and Rayleigh waves.

Fault - a break or fracture in the crust of Earth. Geological - having to do with geology, the study of Earth. Deposition - the process of layering sediments.
