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.
Rayleigh waves or ground roll waves cause the surface of the ground to move up and down. They travel at roughly 90% of the speed of the S waves. Love waves involve the motion of the ground side-to-side, perpendicular to the propagation velocity. They usually travel slightly faster than the Rayleigh waves.
