Question 5 On the Richter scale, the magnitude, M, of an earthquake is given by M = $ log , where E is the energy released by the earthquake measured in joules, and Eo is the energy released by a very small reference earthquake. Eo has been standardized to 104.4 joules. Part A The earthquake in Haiti in 2010 released 2.0 . 10 joules. What was its magnitude on the Richter scale?
