Myanmar: Before & After

Here are two satellite images from NASA's Earth Observatory showing the flooding in Myanmar from Cyclone Nargis. Click on them to enlarge. Here's some of NASA's explanation:

"Flood water can be difficult to see in photo-like satellite images, particularly when the water is muddy. This pair of images from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite use a combination of visible and infrared light to make floodwaters obvious. Water is blue or nearly black, vegetation is bright green, bare ground is tan, and clouds are white or light blue."
