which is one step that geologists use to find the epicenter of an earthquake? they look at data from at least one seismograph. they measure the difference between arrival of p waves and s waves. they draw circles around the epicenter from three locations. they obtain information about the intensity of earthquakes from seismographs.

Answer

Answer:

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

Brief Explanations:

Geologists use the time - difference between P and S wave arrivals at a seismograph station to calculate the distance to the epicenter. Data from at least three stations are then used to triangulate the epicenter. Measuring the P - S wave time difference is a key first step.
