Exclusive: Before And After Satellite Photos Of Uttarakhand Disaster Site | Read

Medium resolution satellite imagery sourced by NDTV from Planet Labs. Inc show before and after images of the ridge-line near Joshimath from where ice, snow and rubble collapsed into the narrow river-valley of the Dhauliganga, a fast-flowing river that joins the Alaknanda river. In the first image, dated February 6, the ridgeline appears intact while the image of February 7, taken shortly after the disaster struck, shows vast areas of the ridge-line bereft of snow and ice. Dust from the impact of ice and snow crashing into the river-valley are also clearly visible in the image of February 7. (Photo Credit: Planet Labs Inc)
