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.
Wave, ripple, breaker, surf refer to a ridge or swell on the surface of water. Wave is the general word: waves in a high wind. A ripple is the smallest kind of wave, such as is caused by a stone thrown into a pool: ripples in a brook. A breaker is a wave breaking, or about to break, upon the shore or upon rocks: the roar of breakers.
