The difference in arrival times of P (primary) and S (secondary) waves provides a method for determining the epicenter of an earthquake. By measuring the time lag between the arrival of these seismic waves at different seismograph stations, seismologists can triangulate the epicenter of the earthquake. P-waves travel faster than S-waves, and the delay in their arrivals at different locations helps determine the distance from the earthquake source to each station.
