Explanation:
Detailed explanation-1: -In order to determine the location of an earthquake epicenter, seismographs from at least three different places are needed for a particular event.
Detailed explanation-2: -Triangulation can be used to locate an earthquake. The seismometers are shown as green dots. The calculated distance from each seismometer to the earthquake is shown as a circle. The location where all the circles intersect is the location of the earthquake epicenter.
Detailed explanation-3: -Having information from just two stations do not narrow down the location because there are many points of intersection. When there are three stations, the point of intersection is defined and often results in a single location.
