The Advanced Land Imager (ALI) on NASA’s EO-1 satellite
these true-color images of the hills north and west of Teresópolis, Brazil,
on February 2, 2011 (top), and May 24, 2010. In both images, forested land
is dark green, while land that has been cleared is light green. The 2011
image shows dozens of tan stripes where the hillsides have been overrun
by mudslides, usually within or adjacent to those light green patches.
