The 2010 Haiti earthquake was one of the world's deadliest national disasters. Shortly after the earthquake, surviving officials of the government of Haiti made urgent request for United States assistance. APAN was requested to assist as the primary communication hub for the Haiti earthquake relief efforts for unclassified, nonmilitary information sharing and collaboration. USSOUTHCOM established an APAN community of interest and within three weeks, APAN had more than 1,800 registered users supporting the relief efforts.
