The equation for the magnitude M of an earthquake is M = log (I/K) where I is the intensity of the earthquake and K is a constant. The magnitude of a 1995 earthquake was 9.0 and the magnitude of a 2004 earthquake was 7.0. Which of the following compares (I)1995, the intensity of the 1995 earthquake with (I) 2004, the intensity of the 2004 earthquake? Multiple choice answers. A. (I)1995= 100(I) 2004 B. (I)1995 = 2(I)2004 C. (I)1995 = (I)2004 + 2 D. (I) 1995 = (I)2004 + 100 E. (I)1995 = 2(I)2004 + 100
