Earthquake Lab: Locating the Epicenter, Determining the Magnitude, and Calculating the Time of Earthquake The goal of this lab is to learn how seismograms are used to locate the epicenter of earthquakes, determine earthquake magnitudes, and to calculate the origin time of earthquakes. A seismogram measures the amount of shaking caused by earthquake waves. The seismogram first records the arrival of P-Waves (Primary), followed by the arrival of the S-Waves (Secondary). The S-P interval is the time difference between the...
