Indo Tibetan Border Police personnel undertake rescue work at one of the hydropower project at Reni village in Chamoli district, in Indian state of Uttrakhund DEHRADUN: Contrary to the initial claims that a glacier burst caused flash floods in Tapovan area of Chamoli district on Sunday, a fresh satellite assessment done by the Dehradun-based Indian Institute of Remote Sensing (IIRS), which is part of the Indian Space Research Organisation (ISRO), has indicated that a landslide in all likelihood triggered an avalanche, resulting in the flash floods. The IIRS report which was submitted to the state government on Monday, says, “A landslide scar at an elevation of 5600 meters in the catchment of Rishiganga probably destabilised freshly- accumulated snow and initiated its downward movement."
