Locating Epicenters
Seismologists can locate the epicenter of an earthquake by triangulation, a method that involves taking seismographic measurements from at least three separate seismic stations. Seismologists measure the time it takes seismic waves to reach the recording stations, as well as the magnitude of the waves, and triangulate the measurements to calculate the location of the epicenter.
