At the forefront of the risk assessment sciences is the assessment of earthquake risk. Countries such as the United States have been targets of extensive earthquake risk assessments to communicate potential damages and loss of life. Few studies, however, have gone beyond the estimation of direct earthquake impacts such as damages to buildings by integrating estimates the socio-economic characteristics of populations. This research seeks to address this missing societal component in earthquake loss modeling using Federal Emergency Management Agency region IV (Alabama, Florida, South Carolina, North Carolina, Mississippi, Kentucky, Georgia, and Tennessee) as a case study. The objective is to find out the potential drivers of social vulnerability that might be contributing factors to potential losses from earthquake. Social vulnerability and economic losses are modeled respectively by using SoVI method and HAZUS-MH model. Finally, the social vulnerability model is integrated with probabilistic impact estimates from potential earthquakes within the region. The results of this research highlights the areas of management concern in which high earthquake losses may be coupled with populations that are unlikely to be able to prepare for, respond to, and recover from damaging earthquake events when they occur.
