New Delhi: A month after the disaster in Chamoli district in Uttarakhand, in which at least 70 persons died and 130 or so more remain missing, scientists from three premier institutions have analysed more data to determine the likely cause of the incident – including heavy snowfall just before the day of the disaster, an overall increase in ambient temperature in the area, a rock and ice avalanche at an altitude of 5,600 metres, and a large volume of meltwater and glacial moraine hurtling down a narrow gorge. ....

New Delhi, March 4 : High resolution satellite imagery indicates that mass movement activities are still occurring where the rock and ice collapsed that led to a disaster in Uttarakhand last month, as per latest observations of national and international scientists.
In case of another slope failure and avalanche, this can be critical for people and infrastructure downstream, close to the riverbed.
On the another disaster in the making, scientists working under the Glacier and Permafrost Hazards in Mountains (Gaphaz) a standing group of the International Association of Cryospheric Sciences and the International Permafrost Association believe large volumes of material have been eroded and deposited along th ....

Himalayan Flood Highlights High Mountain Hazards


9 February 2021 (WMO) A relief and rescue operation is underway in Uttarakhand in the Indian Himalayas, after a part of the Nanda Devi glacier broke off and collapsed causing a massive massive flood in the Rishi Ganga /Dhauliganga river, reportedly causing loss of life and the destruction of two hydropower plants, bursting open existing dams,  and other infrastructure. Many casualties were feared, alongside widespread environmental damage in an ecologically fragile area of Uttarakhand.
The exact cause of the disaster is yet to be ascertained. Early assessments indicate that the event involved a large avalanche of ice and rock.
The role of climate-related drivers, and climate change, was not immediately clear. This was not the first such avalanche from these slopes, as experts have identified a similar (but smaller) event from late-2016. ....
