Movement

President René Préval made a personal appeal for humanitarian aid, and many organizations responded, including the United Nations. The Red Cross focused on bringing aid to victims of the quake, bringing supplies to relief centers, but water and food took days to pass around, due to the lack of distributors. This resulted in more casualties. 
The US navy, in itself, delivered 27000 gallons of water, 532440 bottles of water, 111082 meals, and 4100 kg of medical supplies. 17 ships, 48 helicopters, and 12 airplanes had been assigned to the disaster. 
As a sidenote, social networking such as Twitter and Facebook were used to coordinate ground crew.
