Answer: 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. ... Knowing this helps them calculate the distance from the epicenter to each seismograph.
Explanation: The source of an earthquake is called the focus,
which is an exact location whitin Earth were siesmic waves are generated by sudden realease of stored clastic energy. the epicenter is the point on the surface of earth directly above the focus.this is the location that scientist calculate. The focus is directly below, however, scientist can not determine it's depth.
