The Richter scale measures the magnitude, M, of an earthquake as a function of its intensity, I, and the Intensity of a reference earthquake, Io. log(t) M Which equation could be used to find the intensity of an earthquake with a Richter scale magnitude of 4.8 in reference to an earthquake with an intensity of 1? OA. 4.8 = log(1) OB. 1 = log(4) O C. I = log(4.8) OD. log(8) 4.8 =log(1/I)
