... Location method: difference in velocity of P and S waves provides method of determining epicenter. Based on Vel P > Vel S waves, the greater the distance of travel, the greater the time lag between first arrivals of P and S waves: i.e. the > diff. in arrival times, the > the distance to epicenter.
