Detailed explanation-1: -P waves travel fastest and are the first to arrive from the earthquake.
Detailed explanation-2: -The first kind of body wave is the P wave or primary wave. It’s the fastest kind of seismic wave, and the first to arrive at a seismic station. P waves can move through solid rock and fluids, like water or the liquid layers of the Earth.
Detailed explanation-3: -"P waves” or “primary waves” are the first waves to be detected. These are compressional waves that push and pull as they move through rock and fluids.
Detailed explanation-4: -Compressional waves are also called P-Waves, (P stands for “primary") because they are always the first to arrive. They gave us the first jolt last Friday. Shear waves propagate more slowly through the Earth than compressional waves and arrive second, hence their name S-or secondary waves.
Detailed explanation-5: -P waves, or Primary waves, are the first waves to arrive at a seismograph. P waves are the fastest seismic waves and can move through solid, liquid, or gas. They leave behind a trail of compressions and rarefactions on the medium they move through. P waves are also called pressure waves for this reason.
