Answer

Brief Explanations:

To find the epicenter of an earthquake, geologists measure the time - difference between the arrival of P waves (primary waves) and S waves (secondary waves) at a seismograph station. This time - difference is used to calculate the distance from the station to the epicenter. Data from at least three seismograph stations is needed to triangulate the epicenter. Drawing circles around the epicenter from three locations is part of the triangulation process but comes after calculating distances. Looking at data from only one seismograph is not sufficient. Obtaining information about earthquake intensity is not directly related to finding the epicenter.

Answer:

They measure the difference between arrival of P waves and S waves.
