The United States provides disaster assistance to other nations in many ways. The Office of U.S. Foreign Disaster Assistance (OFDA) coordinates many of these efforts. The OFDA assists disaster affected nations in recovering and rebuilding after a disaster. Private citizens who wish to donate to help in disaster rebuilding efforts are asked to donate to organizations that are part of the relief effort.
The United States is also part of the United Nations, which also coordinates many disaster relief efforts. This particular group in the UN is called the United Nations Disaster Assessment and Coordination (UNDAC). The UNDAC is beneficial to disaster affected nations because it can deploy the resources of many countries and act within a few hours of a disaster.
