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.

One step that geologists use to find the epicenter of an earthquake is B. They measure the difference between the arrival of P waves and S waves.

The epicenter of an earthquake refers to the point where the largest damage was done.

To determine the epicenter of an earthquake three seismographs are used. The time is measured that notes the arrival of the P and S waves.

The longer it takes for these waves to arrive, the farther the epicenter is from the point where the measurement is being taken.

Therefore, option B is correct.

The second one (s and p waves)

Explanation:

They use seismographs to measure intensity, but the differences of s and p waves can allow them to locate the origin
