How do seismologists locate the epicenter of earthquakes?

Q: How do seismologists locate the epicenter of earthquakes?

A: Seismologists studies seismograms from different recording stations to find out the epicenter of an earthquake. Seismologists use triangulation to find the epicenter of earthquakes

When seismic data is collected from at least three different locations, it is used to determine the epicenter by where it intersects. 

The time difference between the P- and S-waves tells us the distance the earthquake is from the seismograph. By measuring the time difference at three stations, seismologists find out the epicenter of the earthquake.

The intersection of the circles, whose radius is equivalent to the distance from the earthquake is used to find the epicenter of the earthquake by seismologists.

  1. very informative post, i really appreciate the effort taken out to explain the method of determining the location of the epicenter of an earthquake. But i can suggest a much better article for understanding the method to locate the epicenter of an earthquake. https://geostudies.org/how-to-locate-the-epicentre-of-an-earthquake/
