__________ is a method that uses distance information determined from 3 seismic stations to uniquely locate the epicenter of earthquake.

You were asked to locate the epicenter of a recent earthquake. Which correct sequence of events should you follow? i. Determine the difference in the arrival time of S and P waves recorded from each of the seismological stations. ii. Use the triangulation method to locate the center. iii. Obtain data from three different seismological stations. iv. Determine the distance of the epicenter from the station.
