This document discusses disaster management, including definitions, classifications, and the phases of disaster management. It defines a disaster as an event that causes human suffering and needs beyond a community's ability to address alone. Disasters are classified as natural (meteorological, topographical, environmental) or man-made (technological, industrial, warfare). The phases of disaster management include preparedness, response, recovery, and mitigation. Preparedness involves planning and training pre-disaster, while response involves immediate relief efforts. Recovery includes temporary housing and medical care, and mitigation aims to reduce future disaster impacts through measures like building codes.
