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 are then used to draw circles (with radii equal to the calculated distances) around each station, and the intersection of these circles gives the epicenter. Looking at data from only one seismograph is not enough. Drawing circles around the epicenter is incorrect as the epicenter is what is being found. Information about earthquake intensity from seismographs is not used to find the epicenter.

Answer:

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