An emergency operations center (EOC) is a central command and control "coordination structure" responsible for managing emergency response, emergency preparedness, emergency management, and disaster management functions at a strategic level during an emergency. Based on the organizational needs of the entity that has implemented the EOC, as well as the emergency being dealt with, the specific responsibilities and tasks executed by a given EOC may vary vastly and could include ensuring the continued operation of a municipality, company, public or emergency service, or other organization.
EOCs were originally created as part of United States civil defense and can be found in many nations, at all government levels, as well as in larger corporations that deal with large equipment or numbers of employees. In corporations and smaller jurisdictions, the EOC may be co-located in the same room as an emergency communications center.
