Severe September Flooding in Brazil

Brazil, S.A.
Heavy rainfall in late September 2007 caused severe flooding in Brazil’s southernmost state, Rio Grande do Sul. More than a dozen cities declared a state of emergency. Several people were killed, and as many as 4,000 lost their homes.



This pair of satellite images (above) captured roughly two weeks apart shows the extent of the flooding. Made with a combination of visible and infrared light, the images highlight the location of water on the surface. Depending on how muddy and/or shallow it is, water will appear blue to nearly black: the shallow, muddy water of the Patos Lagoon appears blue, while the Atlantic Ocean (lower right) is nearly black. Vegetation appears bright green, and clouds are turquoise or white. On September 10, a swath of smoke from intense fires burning in the surrounding countries cuts diagonally across the scene.
