other advances, these contributions have helped to dispel myths about crisis related behaviors, led to improvements in early warning and evacuation systems, and facilitated the ways communities and regions prepare for disasters.

Disaster research, which has focused historically on emergency response and recovery, is incomplete without the simultaneous study of the societal hazards and risks associated with disasters, which includes data on the vulnerability of people living in hazard-prone areas. Historically, hazards and disaster research have evolved in parallel, with the former focusing primarily on hazards vulnerability and mitigation, the latter primarily on disaster response and recovery, and the two veins intersecting most directly with common concerns about disaster preparedness. It is vital, however, that future social science research treat hazards and disaster research interchangeably and view the above five core topics of hazards and disaster research within a single overarching framework (see Figure S.1). Such integration also provides the foundation for increased collaborative work by social scientists with natural scientists and engineers.
