They call it the Primary wave or a P-wave
primary
The primary factor that determines the velocity of a wave is the medium through which the wave is traveling.
Primary Wave (P wave)
The primary body wave that is a longitudinal wave is the P-wave (primary wave). It is the fastest seismic wave and travels through the Earth's interior by compressing and expanding the rock in the direction of the wave's propagation.
A primary wave is a strong vibration or wave that hits earths surface (P) and a secondary wave (S) is a wave that hits soon after but not nearly as big.
The primary wave (P-wave) vibrates in the same direction as the wave propagation. This means that the particles in the material move back and forth parallel to the direction of wave travel as the P-wave passes through.
