The Robert T. Stafford Disaster Relief and Emergency Assistance Act (referred to as the Stafford Act-42 U.S.C. 5721 et seq.) authorizes the President to issue "major disaster" or "emergency" declarations before or after catastrophes occur. Emergency declarations trigger aid that protects property, public health, and safety and lessens or averts the threat of an incident becoming a catastrophic event. Given their purpose, the emergency declarations may precede an event. A major disaster declaration is generally issued after catastrophes occur, and constitutes broader authority for federal agencies to provide supplemental assistance to help state and local governments, families and individuals, and certain nonprofit organizations recover from the incident.
