These images show the hills in the north of Teresópolis, Brazil, on May 24, 2010 and on February 2, 2011. In January 2011, a series of devastating landslides occurred, claiming the lives of 860 people. In the image on the right-hand side, the light brown stripes indicate the mudslides. This natural disaster was caused by the construction of favelas in steep terrain: In order to build the settlements, many trees were cut down whose roots had been ensuring the stability of the ground. What is more, the ground could not absorb enough water to prevent the heavy rainfall from resulting in mudslides.
