Question: How does triangulation determine the epicenter of an earthquake? Need Assignment Help? View Available Hint(s)for Part A On a map, a circle is drawn around each of three recording stations, with the radius being the distance from the station to the epicenter of the earthquake. The epicenter is located where the three circles intersect. The distance from a recording center to a foreshock, the earthquake itself, and an aftershock are averaged together. A circle made with this radius is drawn around the recording center; the epicenter is located within this circle. The time that it takes a P wave, an S wave, and a surface wave to reach a recording station are added together, and the average of these three times is calculated. This is done at three different recording stations; the station that has the lowest average of arrival time is closest to the epicenter of the earthquake. On a map, three lines are drawn to connect three stations that recorded the earthquake. The epicenter is known to be somewhere within this triangle. The distance from a recording center to a foreshock, the earthquake itself, and an aftershock are plotted against time on an XY graph.
