How do geologists determine the location of an earthquake's epicenter?
By measuring the magnitude of the earthquake using the Mercalli scale.
By analyzing the chemical composition of rocks at the earthquake site.
By using seismograph data to triangulate the distance from multiple seismic stations.
By directly observing the surface rupture and fault displacement at the earthquake source.

By using seismograph data to triangulate the distance from multiple seismic stations.
Explanation: Seismographs record P- and S-wave arrival times. The time difference gives the distance from a station to the epicenter. Circles drawn around three or more stations (with radii equal to those distances) intersect at the epicenter. The Mercalli scale measures intensity, rock chemistry is irrelevant, and surface rupture may not always be visible.
