Katrina Cataclysm Does Duration of Residency and Prior Experience Affect Impacts, Evacuation, and Adaptation Behavior Among Survivors?

This study explores the extent to which people's prior experience of a natural disaster influenced subsequent behavior concerning the threats of a hydrometeorological disaster and if duration of residency in a disaster-prone landscape affects the extent of preparedness for an impending disaster. Mixed methods research strategies involving survey, field observation, and participant observations at several locations including rescue and evacuation centers in New Orleans, Louisiana, Austin, Texas, and Lawrenceville, Georgia, were used, during the immediate impact phase, emergency shelter phase, and postimpact and recovery phase of Katrina catastrophe. For the survey, a sample of 598 subjects completed a 15-page, 54-item questionnaire addressing various aspects of the Katrina flood in the New Orleans Metropolitan Area. The qualitative aspect consists of field observations of the event, interviews, and direct comments by the victims dispersed across the South. In the regression analysis performed, prior experience was found to be less important than friends' and family members' influence in determining evacuation behavior. However, duration of residency and prior experience were found to be slightly significant in predicting the odds of evacuation.
