Answer:
not entirely sure what your asking but have some notes
Explanation:
Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surface waves, which arrive at seismic recording stations one after another. Both P and S waves penetrate the interior of the Earth while surface waves do not. Due to this, P and S waves are known as "body waves". Surface waves arrive last and are the least interesting to seismic tomographers because they don't penetrate deep inside the Earth, therfore provide little information about inacessible terrain.
Below, some of the major differences between P and S waves are highlighted.
P Waves:-
known as LONGITUDINAL waves
or compressional waves
1st to arrive at seismic stations
shakes the ground in the direction they propagates
Travels through the Earth's core
