The epicenter of an earthquake can be located using from at least three seismographic stations.

The epicenter of an earthquake can be located using triangulation from at least three seismographic stations.

It is the location directly above it on the surface of the earth. In about 75% of earthquakes, the focus is in the top 10 to 15 kilometers of the crust.

In order to determine the epicenter of the earthquake we use a method called triangulation. In triangulation, the distance of the earthquake to the station is determined from a seismogram at a seismograph station. This distance is used as the radius to plot a circle.

Explanation:

The epicenter of an earthquake is a point on the earth surface which is directly above the focus.

To determine the epicenter of the earthquake we use a method called triangulation. In triangulation, the distance of the earthquake to the station is determined from a seismogram at a seismograph station. This distance is used as the radius to plot a circle. We do this for three places. Where they intersect marks the epicenter of the earthquake.
