Abstract

Risk assessment frameworks such as HAZUS-MH (FEMA, 2010) have been used globally to estimate potential losses like physical damage to structural establishments, economic loss, shelter requirements, displaced households, etc. due to multi-hazards like earthquake, flood and hurricane hazards. However, HAZUS-MH fails to consider interdependencies between physical and social capacities of affected communities. The present study aims to develop a conceptual risk assessment framework for storm hazards in coastal communities that addresses these limitations through an integrated physical and social vulnerability assessment applied to Hampton Roads, Virginia. By including interdependencies, interactions between the physical and social vulnerability will be studied. We hypothesize that changes in housing occupancy status affect the physical damage and changes in population density affect the social vulnerability. Therefore, the integrated physical and social vulnerability will change in response to a current event and therefore make the same region more or less impacted in a subsequent future event.
