Disaster management is best defined as the avoidance of risk through preparation and the disaster response in the wake of an emergency. Emergencies can be natural or man-made disasters including those requiring evacuations, quarantine, mass decontamination and humanitarian aid. This book delves into emergency services, the approach to mitigation and preparedness, international organizations that handle emergencies and disasters, and a specific focus on the emergency management of the United States.
