Emergency management is the planning, organizing, and carrying out of the responsibilities for all humanitarian aspects of emergencies (preparation, response, mitigation, and recovery). Reducing the negative impacts of all risks, including disasters, is the aim.
An emergency, according to the World Health Organization, is a situation in which regular operations are disrupted and immediate action (management) is required to keep it from turning into a disaster, which is much more difficult to recover from. This involves gathering, managing, and analyzing large amounts of data with the goal of incorporating data-driven strategies into each stage of the emergency management cycle.
