Description: The preliminary modeled distribution of fatalities from ground motion uses building exposure databases derived from NASA sensors combined with traditional loss estimation. These ground motion only casualties can be compared with actual reports of fatalities to identify potential areas of under-reporting. These results are dependent on the USGS ShakeMap ground motion estimates, which are subject to change. USGS ShakeMap ground motion estimates are combined with an ImageCat exposure database for Nepal. Empirical damage functions from Jaiswal et. al. (2011) are combined with ATC 13 fatality models. The total estimate of fatalities from this analysis is approximately 6,000 fatalities and is estimated to be within a factor of 2. An important caveat is that the process only estimates fatalities from ground motion effects, not landslides. Jaiswal, K., Wald, D., & D'Ayala, D. (2011).
