These images send shivers down the spine Last Sunday, February 7, in the district of Chamoli, India, a large piece of a Himalayan glacier broke away. Overlooking the Alaknanda River which it fed into, the immense mass caused the river to overflow, generating a gigantic torrent, which was filmed by tourists present there. The images, posted on social networks, quickly went around the world.An unmitigated disasterThe water has swept away everything in its path: roads, bridges, houses, two power plants and above all causing a dam to fail. A witness told Indian television:There was a cloud of dust when the water came through. The earth was shaking like an earthquake. A more than provisional toll lists 7 dead and 125 to 200 missing.Most of these missing people are workers at the two power plants that were engulfed by the disaster. About 20 employees are 'stuck in a tunnel' in one of the power plants. #WATCH | Water level in Dhauliganga river rises suddenly following avalanche near a power project at Raini village in Tapovan area of Chamoli district. #Uttarakhand pic.twitter.com\/syiokujhns— ANI (@ANI) February 7, 2021 To rescue any potential survivors, hundreds of soldiers and paramilitaries were dispatched to the scene, with helicopters and military planes.
