The term FEMA trailer, or FEMA travel trailer, is the name commonly given by the Unite States Government to many forms of temporary manufactured housing assigned to the victims of Hurricane Katrina and Hurricane Rita by the Federal Emergency Management Agency (FEMA). FEMA trailers were used to house thousands of persons in South Florida displaced by Hurricane Andrew in August 1992, for as long as two and a half years. They provide intermediate term shelter intended to function longer than tents used for immediate shelter after a disaster. They serve a similar function to "earthquake shacks" erected to provide interim housing after the 1906 San Francisco earthquake.
