Before and After ASTER images, Tropical Storm Jeanne, Haiti

The following pairs of images illustrate a major drainage upstream of the heavily damaged city of Gonaives, Haiti that was responsible for catastrophic flooding in this coastal town. On the left is shown pre-hurricane conditions (8-August-2001) and on the right those following Tropical Storm Jeanne (image is for 26-September-2004).

The flooding originated in the highlands, and scoured a new channel as wide as 500 m (.3 mile) over a length of approximately 15 km (9 miles), upstream of the city. The comparison images downstream clearly show the path of the water and sediment into the city. See also http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3
