Catastrophic disasters require additional leadership capabilities because extreme events overwhelm local capabilities and damage emergency response systems themselves. Therefore, leaders at all levels must adapt and rebuild the response system, even while they are addressing the pressing needs of the disaster itself. Leaders can minimize or maximize the effects of the trigger event(s) by their actions and competence in dealing with this especially difficult set of overlapping and, frequently, even inconsistent tasks. This case studies the effects of the Katrina—Rita hurricanes on New Orleans and systematically examines how poor leadership—lacking a series of critical competencies required in extreme conditions—can maximize catastrophic events.
