Which steps do geologist use to find the epicenter of an earthquake? Select three options.

They look at fate from at least three seismographs.

They locate the point where circles intersect one another.

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.

They measure the difference between arrival of P waves and S waves, They draw circles around the epicenter from three locations

"They measure the difference between arrival of P waves and S waves" This method is used to determine how far seismograph is from the epicenter. It is not the direct step of finding epicenter but after finding this distance , epicenter in located.

In the second step the distance measured above is converted to the unit of map and  three circles are drawn from the location of seismograph

Explanation:

a is the answer i believe.
