NASA’s Earth Observing-1 satellite with the Advanced Land Imager (ALI) instrument aboard took an image centered on Port-au-Prince, Haiti on Friday, January 15, 2010, three days after the earthquake. The picture on the left is the entire ALI image. The lower right image is a zoom-in of Port-au-Prince, while the upper right image is the same view taken in September 2008, one week after Hurricane Ike. Significant features can be seen in both zoom images. Hurricane Ike unleashed torrential rains that caused severe flooding as depicted (upper right image) in the excessive discharge of sediment at the river delta, just north of downtown Port-au-Prince. The pier in the center of the 2008 image collapsed during the earthquake and is not visible in the 2010 image (lower right image).
