Question

Quizplus · Accepted Answer

The S-P timing method requires seismograms from at least three recording stations. By measuring the time difference between the arrival of the P-wave and the S-wave at each station, the distance to the epicenter can be calculated. The intersection of three or more distance circles can then be used to locate the epicenter.
