|Where's my Epicenter?|
In this exercise, students will use two shake intensity maps with Modified Mercalli Intensity values, one of the New Madrid Earthquake and the other of Southern California, to determine the location of earthquake epicenters. They will draw curves that enclose areas of similar intensity (as given by the numerical values representing the reports of witnesses), look for patterns or closures in the isoseismal lines, and choose their epicenter location based on the patterns they see. Study questions, links to additional information on the Modified Mercalli Intensity Scale, to felt reports, and to example maps, are included.
