"The devastation in Haiti caused by the 7.0 magnitude earthquake on 12 January 2010 prompted the longest and largest U.S. military effort in a foreign disaster relief operation. The earthquake destroyed vast areas of Port-au-Prince, the nation's capital, as well as a number of communities to the west of the capital, killing an estimated 230,000 persons and leaving thousands trapped in the wreckage and over two million without shelter. At the peak of Operation Unified Response, 1 February 2010, Joint Task Force-Haiti (JTF-H) consisted of over 22,000 service members, 58 aircraft, and 23 ships. With the stand-down of JTF-H on 1 June, Operation Unified Response lasted nearly five months. This article contains our initial observations and recommendations to after action reviews and lessons that our military and interagency community should learn from as we prepare for the next foreign disaster."
