Natural and human-made disasters place an enormous physical, social, economic, and emotional strain on those caught up in its stress. Preexisting emotional strengths and weaknesses are accentuated during a person's response to a disaster. Most, as noted in this entry, regardless of the severity of the community and individual insult, manage to perform beyond their expectations; a small proportion is unable to do so and requires nurturing from others. This entry describes a community's response to the consequences of Hurricane Katrina, its wind, rain, subsequent flooding, and delayed relief efforts.
