Which is used to find the epicenter of an earthquake?
Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Each seismograph records the times when the first (P waves) and second (S waves) seismic waves arrive.
