# How Do Scientist Locate the Epicenter of an Earthquake?

Seismologists are scientists that study earthquakes. The place where the earthquake starts beneath the surface of the earth is called the hypo-center, and the area above this that is above the surface of the earth is known as the epicenter. Seismologists use a method that is called triangulation to find out where the earthquake occurred. Three seismographs are used to find the location. These are combined and the intersection that occurs when circles are made from the distance of the station to the earthquake shows where the epicenter is located.
