GEOLOGY

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: -Seismic stations detect earthquakes by the tracings made on seismographs. Tracings made at three separate seismic stations are needed to locate an earthquake epicenter.

Detailed explanation-3: -You need one because the epicenter will be somewhere along that circle. You need three because three is the minimum number of circles that will intersect at one point. It’s not possible to do this with only seismic data.

Detailed explanation-4: -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. Every earthquake is recorded on numerous seismographs located in different directions.

Detailed explanation-5: -Locating an Epicenter A seismograph measures seismic waves. Three seismograph stations are needed to determine the location of an epicenter. 1.
