Uttarakhand on Sunday experienced huge flooding after a piece of the Nanda Devi glacier burst at Joshimath in Uttarakhand's Chamoli locale, according to authorities. Bringing back frequent recollections of the 2013 Kedarnath disaster, the glacial mass break caused huge destruction in the upper regions of the naturally delicate Himalaya. 

According to the accessible data, more than 150 workers working at a power project in Tapovan-Reni are missing while salvage groups have recuperated 10 bodies up until this point. The power project was totally washed off and homes en route were additionally cleared away as the waters surged down the mountainsides in a furious deluge.

In the interim, every one of the 16 individuals who were caught in a passage close to the Tapovan region has been securely saved by Indo-Tibetan Border Police (ITBP) staff. 

It's not yet understood what caused part of the Nanda Devi glacial mass to snap off Sunday morning, sending floodwater flowing downstream toward power plants and towns in India's northern province of Uttarakhand. 

Experts have called the breaking of an enormous lump of the Nanda Devi ice sheet an uncommon occurrence, satellite, and Google Earth pictures didn't show a lake underneath the segment of the ice sheet that burst. 

GLacial lakes are water bodies that structure underneath large glaciers and stream inside the huge ice sheets. Now and again, they make sufficient strain to break off enormous lumps of glacial masses. 

In the Uttarakhand ice sheet burst, it is estimated that water pockets may have created inside the Nanda Devi glacier causing the misfortune. The development is connected to environmental change and a worldwide temperature alteration. The whole Himalayan-Hindukush stretch of mountains is viewed as a focal point of environmental change. 

Seismic action and the development of water pressure can make ice sheets burst, however, one specific concern is environmental change. High temperatures combined with less snowfall can quicken melting, which makes water ascend to conceivably hazardous levels. 
Most mountain ice sheets around the planet were a lot bigger previously and have been dissolving and contracting significantly because of environmental change and a worldwide temperature alteration.
