Hello all as you all know that a tragedy happen in Uttarakhand. In this blog we will tell you all about Uttarakhand tragedy
It was a normal pleasant winter morning in Raini village (Chamoli district) of Uttarakhand until the residents were jolted at by a loud sound and sight of huge torrents of water and sludge in the Dhauliganga river coming towards them.
The direct cause and source of the is currently unknown though early reports indicated a glacial lake outburst flood as being likely. The scenes brought back to the people horrifying memories of the 2013 Kedarnath deluge that killed thousands.
Originating from Vsudhara Tal, Dhauliganga flows in a meandering course. Known for its spectacular route and whitewater rafting, the river turned into a deathly torrent on Sunday after a part of the Nanda Devi glacier broke of and collapsed into it.
Collapse of the glacier led to rippling fash foods in the Dhauliganga and the Rishiganga and also impacted the Alaknanda.
Dhauliganga is joined by Rishiganga river at Raini, where the disaster at the power project dam took place.
The avalanche completely inundated the Rishiganga Power project — a smaller hydroelectric dam on the river in Chamoli. The glacier broke, and with it a portion on the mountain- boulders and debris all came down and flooded the power project here.
Loss of life and money in Uttarakhand tragedy
Footage of the disaster showed a fast-moving avalanche of dust, rock and water barreling through the narrow gorge in Chamoli district, in the Himalayan state, and sweeping away parts of a dam as well as buildings, trees and people in its path. Those living further down the river were urged to evacuate from the rising waters.
Over hundred persons are missing after the fash food, caused by the splintering of a glacier, washed away two hydel power projects — the Rishiganga small hydro project and the National Thermal Power Corporation’s Tapovan project on the banks of the Dhauliganga river in north Uttarakhand. Some 176 laborers were working on that project, which has two tunnels. Roughly 15 people managed to get out of one tunnel after getting word of the avalanche on their mobile devices, seven persons were killed and over 125 reported missing, and the number could rise as the details were still being ascertained.
Indian Army and members from India’s National Disaster Response Force (NDRF) have been assisting rescue efforts, Rescue teams worked throughout the night to find survivors and recover bodies.
Effect of climate change
Environmental experts attributed the Nanda Devi glacial melt to global warming. Glacier retreat and permafrost thaw are projected to decrease the stability of the mountain slopes and increase the number and area of glacier lakes. The number and area of glacier lakes will continue to increase in most regions in the coming decades, and new lakes will develop closer to steep and potentially unstable mountain walls, where lake outbursts can be more easily triggered.
Climate change has increased snowfall and rainfall, and warmer winters had led to the melting of a lot of snow. The thermal profle of ice, was increasing. Earlier the temperature of ice ranged from -6 to -20 degree Celsius; it is now -2 making it more susceptible to melting.
Major natural disasters in the region over the past three decades-
Uttarakhand state is home to the source of the Ganges River, the site of Hinduism’s famous Char Dham pilgrimage and Rishikesh. But the area is also prone to flash floods and landslides — in 2013, the state was hit by what was dubbed by the area’s chief minister as a “Himalayan tsunami.”
1991- An earthquake broke out in Uttarkashi of 6.8 magnitude in October 1991, and at least 768 people were killed and thousands of homes were destroyed.
1998- The small village of Malpa was wiped out by a landslide, and nearly 255 people were killed. The debris partially blocked Sharda river.
1999- An earthquake of 6.8 magnitude hit Chamoli district killing over 100 people. Several ground deformations were observed as a result of the earthquake.
2013- in June 2013 a cloudburst in Uttarakhand caused devastating floods and landslips. According to the records more than 5700 people were killed in the disaster.
