The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security, initially created by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders on April 1, 1979. The agency's primary purpose is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and state authorities.
FEMA in Supervolcano
After the Yellowstone Supervolcano erupted, FEMA did what it could in the extraordinary disaster including establishing a number of refugee camps at the outskirts of the ashfall. The camps stretched from Iowa to Louisiana on the east side of the eruption and from Washington state to California on the west. They were given patriotic sounding names: Camp Constitution, Camp Independence, Camp Federalist, and Camp Liberation.
