Which organization is primarily responsible for major disaster management in the U.S.?

The Federal Emergency Management Agency (FEMA) is primarily responsible for major disaster management in the United States. FEMA's mission encompasses coordinating the federal government's response to natural and human-made disasters, ensuring preparedness, response, recovery, and mitigation efforts are effectively managed across local, state, and federal levels. This includes providing assistance to those affected by disasters and managing resources swiftly to help communities rebuild.

While the Department of Homeland Security oversees FEMA and other agencies to ensure national security and resilience against hazards, it is FEMA that operates directly in the realm of disaster management. The Environmental Protection Agency and the Occupational Safety and Health Administration have important roles in environmental health and workplace safety respectively, but they do not lead disaster management efforts in the same capacity as FEMA. Thus, FEMA's focus on disaster response and recovery solidifies its role as the primary organization managing such events.
