GEOLOGY

Detailed explanation-1: -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-2: -How is triangulation method used to locate the epicenter of an earthquake? On a map, a circle is drawn around each of three recording stations, with the radius being the distance from the station to the epicenter of the earthquake. The epicenter is located where the three circles intersect.

Detailed explanation-3: -First step of finding epicenter. Collect data from 3 different seismographs. Second step of finding epicenter. Find the difference between the arrival time of the P and S waves. Third step of finding epicenter. Use the P and S graph to find the distance to the epicenter. Fourth/Last step of finding epicenter.
