The s-p value is a measure of the difference in time between the TIME OF ARRIVAL OF THE FIRST P WAVE and the FIRST S WAVE.

Explanation:

The s-p value is important in measuring the time in which the P and S wave arrives a seismic revising station from an earthquake.

The P and S wave are body waves, a class of seismic waves that travels through the interior of the Earth.

P wave travels faster than S waves.

P waves are involved in the forward and backward movement of matter.

S waves are involved in the side- to-side (perpendicular) movement of matter.
