Very very fast
P waves arrive a couple seconds to a few minutes before s waves.
P waves (primary waves) are longitudinal or compressional waves. In solids, these waves generally travel almost twice as fast as S waves and can travel through any type of material. In air, these pressure waves take the form of sound waves, hence they travel at the speed of sound. Typical speeds are 330 m/s in air, 1450 m/s in water and about 5000 m/s in Granite.S waves (secondary waves) are Transverse_waveversewaves or shear waves, which means that the ground is displaced perpendicularly to the direction of propagation. In the case of horizontally polarized S waves, the ground moves alternately to one side and then the other. S waves can travel only through solids, as fluids (liquids and gases) do not support shear stresses. Their speed is about 60% of that of P waves in a given material. S waves arrive second in a seismic station because of their slower speed.

Seismic waves consist ofP waves which travel through the Earth fast. They compress the medium they travel through;S waves which also travel through the Earth, shearing the solid Earth as they go. S waves do not travel through liquid;Surface waves which can cause the Earth to undulate like water waves or surface waves that cause the Earth to shear.
