Disaster imposes adverse consequences upon community populations in several different but synergistic ways. The physical infrastructure of the community may be disrupted and its capability in providing basic elements of the population at risk’s Hierarchy of Needs may be impaired. Vulnerabilities inherent in the community population may be revealed as compensatory day to day practices for their mitigation are weakened or become impossible. Finally, the disaster itself may cause additional injuries to the population whose urgent remedy may be significant or critical.
