Exclusive: Satellite Images of Uttarakhand Disaster

High resolution images available with NDTV indicate the clearest ever sequence of events leading up to the glacier burst in Uttarakhand's Chamoli on Sunday, which left 30 dead and over 170 missing. Before and after images with fairly incredible clarity show the magnitude of the avalanche. An image from February 6 shows an ice and snow covered ridge line, a part of the Trishala glacier. But after the avalanche, on February 8, an entire chunk of ice is missing. (Photo Credit: Planet Labs Inc)
