Introduction: The Scope and Nature of the Problem
A disaster is an unplanned event in which the needs of the affected community outweigh the available resources. A disaster occurs somewhere in the world almost daily, but these events vary considerably in scope, size, and context. Large-scale disasters with numerous casualties are relatively unusual events. Certain widely publicized disasters, including events such as the terrorist attacks on September 11, 2001, Hurricanes Katrina and Sandy, and the Boston Marathon bombing, have focused people’s attention on disaster planning and preparedness. Disasters are becoming more frequent, and the number of persons affected is also increasing. This greater morbidity is attributable not only to the greater number of events, but also to population dynamics, location, and susceptibilities.
While these incidents have led to an increase in general disaster awareness, the relative infrequency of major catastrophes affecting defined populations leads to a certain degree of complacency and underestimation of the impact of such an event. In the wake of a large-scale event, public attention focuses on disaster planning and preparedness and the resources dedicated to improving response and resiliency surge
