How do you to use triangulation to locate an earthquakes epicenter?

To locate an earthquake's epicenter using triangulation, you need data from at least three seismic stations. Each station records the arrival times of seismic waves, allowing you to calculate the distance from each station to the epicenter based on the difference in arrival times of P-waves and S-waves. By plotting these distances on a map, the point where the three circles intersect indicates the epicenter's location. This method relies on the principle that the farther the epicenter, the longer the time it takes for seismic waves to reach the stations.
