Detailed explanation-1: -P waves travel through solid and liquid, but S waves do not travel through liquid.
Detailed explanation-2: -A P wave is a sound wave traveling through rock. In a P wave, the rock particles are alternately squished together and pulled apart (called compressions and dilatations), so P waves are also called compressional waves. These waves can travel through solids, liquids, and gases.
Detailed explanation-3: -In P or compressional waves, the vibration of the rock is in the direction of propagation. P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation.
Detailed explanation-4: -S-waves cannot travel through liquids. When they reach the surface they cause horizontal shaking.
