Emergency management.

Emergency management is the field that deals with the preparation for and recovery from disasters, both natural and manmade. Natural disasters include floods, hurricanes, wildfires, tornadoes, tsunamis, and earthquakes. Manmade disasters include arson, acts of war or terrorist attacks, industrial accidents, and transportation accidents involving air, automotive, or rail travel. The management element comes from the preparedness, reaction, and recovery related to protecting citizens from catastrophes. Emergency management operations are generally run by government bodies at the national or local levels, but citizens and communities can also volunteer assistance and are often trained by nongovernmental organizations to aid in relief efforts.
