Question

Problem 5 (15%) e occurred in a mountain area. The highest Mercalli intensity scale is 9 (IX). bers of people in Mercalli intensity scale zones 9 (IX), 8 (VIII),7 (VII), and 6 (VI) 0.2 million, 1.33 million, and 11 million, respectively, all with a coefficient of variation of 0.1. The risk of the people in intensity scale 5 or weaker were estimated to be 0.08 million, zones can be ignored. The potential loss of life in each intensity zone can be estimated by the product of number of people N exposed and the fatality rate FR. The fatality rate FR has a coefficient of variation of 0.2 and a mean value of 0201 353 FR = 41 2.8 Inl- 23.575 while D is the standard normal cumulative distribution function and I is the Mercalli intensity scale. Assume that N and FR are independent and both follow the Normal distribution. Determine the mean and standard deviation of the number of potential loss of life caused by the earthquake. State your assumptions clearly
