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.
Different types of seismic waves include: Surface waves: Seismic waves that travel along the Earthâs surface. Body waves: Seismic waves that travel through the Earthâs interior. There are two types: Primary waves (P waves): Body waves that compress and expand rock in the direction the waves travel (like a slinky). Secondary waves (S waves): Body waves that shake material at right angles to the direction the waves travel (like shaking a rope). Solid rock transmits S waves, but gases and liquids do not.
