Earthquakes The Richter scale is used to measure the intensity of earthquakes, where intensity corresponds to the amount of energy released by an earthquake. If an earthquake has an intensity of x, then its magnitude, as computed by the Richter scale, is given by R (x) = log , where l, is the intensity of a small measurable earthquake. a. On July 26, 1963, an earthquake in Yugoslavia had a magnitude of 6.0 on the Richter scale, and on August 19, 1977, an earthquake in Indonesia measured 8.0. Find the intensity x for each of these earthquakes if l, = 1. b. How many times more intense was the Indonesian earthquake than the Yugoslavian earthquake?
