Using the S-P timing method,epicentres can be located using seismograms from a minimum of ______ recording stations.

Question

Quizplus · Accepted Answer

The S-P timing method requires at least three recording stations to locate the epicenter of an earthquake. By measuring the time difference between the arrival of the S and P waves at each station, the distance to the earthquake can be calculated. By intersecting these three distances, the location of the earthquake's epicenter can be determined. One or two recording stations are not enough to accurately locate the epicenter. Four or more stations can improve the accuracy of the location but are not necessary to obtain a reliable estimate.
