Explanation:

The Federal Emergency Management Agency (FEMA) is an organization of the United States Department of Homeland Security, at first made by Presidential Reorganization Plan No. 3 of 1978 and actualized by two Executive Orders on April 1, 1979. The organization's main role is to arrange the reaction to a calamity that has happened in the United States and that overpowers the assets of the neighborhood and state experts. The legislative head of the state where the debacle happens must proclaim a highly sensitive situation and formally demand from the president that FEMA and the government react to the disaster.
