GEOLOGY

Detailed explanation-1: -P waves travel fastest and are the first to arrive from the earthquake.

Detailed explanation-2: -Primary waves In air, they 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.

Detailed explanation-3: -P waves or Primary waves are the first waves to hit the seismographs when an earthquake strikes. They are longitudinal waves which means that the direction of motion and propagation are the same.

Detailed explanation-4: -In air, P waves take the form of sound waves and therefore move at the speed of sound, 330m/s at sea level. Some people even report hearing an earthquake (due to the higher frequency P waves vibrating or rustling objects) before they feel the S waves’ arrival.

Detailed explanation-5: -Velocity of Body Waves P-waves will always travel faster than S-waves due to the way they deform the material they are traveling through and the restoring forces of that material. Its also important to understand that S-waves can’t travel through liquids.
