Properties of Compressional or P waves. The first kind of body wave is the P wave. This is the fastest kind of seismic wave their name derives for the fact that P is an abbreviation for primary, first wave to arrive. The P wave generally travel at speeds between 1 and 14 km/sec. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.
Because of the size of these plates, earthquake waves carry huge amounts of energy. In this lesson, we discussed four types of seismic waves: P-waves, S-waves, Rayleigh waves and Love waves. The first two are body waves, the latter two are surface waves. Love waves cause the most damage and P-waves the least. Thanks to our study of seismic waves, we have a better idea of what to expect when an earthquake hits. Through this knowledge and better preparation, we can save both property and human lives.
