The fastest of the three waves and the one that is first detected by seismographs is the P wave or primary wave. The P waves can move through both liquid and solid rock. P waves compress and expand matter as they move through it.
P-wave is one of the two main types of elastic body waves, called seismic waves in seismology. P-waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph. P-waves may be transmitted through gases, liquids, or solids.
