News and Image Courtesy:Nasa Earth Observatory Cyclone Nargis, the first of the 2008 cyclone season in the Northern Indian Ocean made landfall with sustained winds of 130 mph and gusts of 150-160 mph, which is the equivalent of a strong Category 3 or minimal Category 4 hurricane. News reports state that at least 10,000 people were killed and countless others missing, conditions unknown even now. When A Cyclone Hits The View Flood water can be difficult to see in photo-like satellite images, particularly when the water is muddy. The 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. The Hit On April 15 (top), rivers and lakes are sharply defined against a backdrop of vegetation and fallow agricultural land. The Irrawaddy River flows south through the left-hand side of the image, splitting into numerous distributaries known as the Mouths of the Irrawaddy. The wetlands near the shore are a deep blue green. Cyclone Nargis came ashore across the Mouths of the Irrawaddy and followed the coastline northeast. The entire coastal plain is flooded in the May 5 image (bottom). The fallow agricultural areas appear to have been especially hard hit. For example, Yangôn (population over 4 million) is almost completely surrounded by floods. Several large cities (population 100,000,500,000) are in the affected area. Muddy runoff colors the Gulf of Martaban turquoise. More Analysis and Twice Daily updated images here: NASA EO
