The American Geosciences Institute represents and serves the geoscience community by providing collaborative leadership and information to connect Earth, science, and people. Direct student pairs to independently complete the tutorial/simulation to find an epicenter location via the triangulation method and compute the earthquake magnitude: The simulation directs students to look at three simplified seismograms from seismic stations in Chile (Talca, Santiago, Osorno) and select the correct measurements of the S-P intervals. Adjust the timing to the class period, remembering that you will need time to introduce the investigation, clean up afterwards, and re-set up for the next class (if you are working with more than one class). If a quake is near the seismograph, the S-waves arrive shortly after the P-waves. Fill Locating The Epicenter Of An Earthquake Worksheet Answers, Edit online.
