Based on the difference in arrival times of p-waves and s-waves seismologists are able to determine how far away the epicenter of the earthquake was.

Distance to the epicenter of an earthquake.
Since p and s waves travel at different speed through the same medium. Their arrival times at a given location can be used to determine where the epicentre of the earthquake is,

Actually the different arrival time of p wave and s wave helps to find the distance of epicenter. The arrival time on 26th Dec 2004 helped me to issue the warning of Tsunami. Because I sensed the earthquake wave for an unbelievable time of 12 minutes 2 hours before Tsunami struck our Indian coast. As per the concept of Richter scale it should be from major earthquake only. As I have studied the book written by Mr Bruce Bolt that says that we should stay away from beaches because the Tsunami may strike long after the shaking is stopped. But my warning was ignored.
