Earthquake Lab The goal of this lab is to learn how recording of earthquakes are used to locate earthquakes and determine their magnitudes. Locate the Epicenter 1. Determine the S-P interval from the 3 seismograms shown on the following page, and enter the results in the table below. The time is shown in seconds. Then, use the S-P travel time curve (below) to determine the distance between the station and the epicenter and enter the data into the table. 2. Next, take a compass and set its radius to the epicentral distance for each station and draw arcs around each station. Ideally, the three arcs should intersect at a single point, which is the epicenter if they do not, you should go back and check your work. Clearly mark the location of the epicenter. 3. Is there a known fault in the vicinity of the epicenter that is
