Uttarakhand floods: Glacier bursts in winter 'next to impossible', say defence scientists

Sabotage cannot be ruled out; DRDO team to study site.

A team of DRDO'S Defence Geoinformatics Research Establishment (DGRE) is heading for Joshimath to study the exact cause of the glacier burst that triggered flash floods in Uttarakhand on Sunday.
The floods, which took place after a portion of the Nanda Devi glacier broke off in the Tapovan area, near the Indo-China border, have left up to 150 feared dead and damaged multiple locations including a hydropower plant in the region. Rescue efforts are underway as many are feared trapped under the Tapovan tunnel.

But, scientists monitoring glaciers and avalanches in the region are surprised as they say glacier bursts do not take place in winters.

Defence scientists say that a glacial lake outburst flood (GLOF), a type of outburst flood that occurs when the dam containing a glacial lake fails, is a near impossibility under present climatic conditions: The area is surrounded by snow-capped mountains with temperatures of minus 20 degrees Celsius.
"During winters, glaciers are formed as snow doesn't melt due to the negative temperature. To my understanding, glacier burst in this season is next to impossible. I haven't studied such an incident in the last 50 years," said a defence scientist, who added that the exact cause can be established after studying satellite images.

Without ruling out the possibility of sabotage, defence scientists indicate that several militaries in the world use mountain resources as a weapon to hit enemy territory.

The Rishiganga hydropower project near Raini village in Uttarakhand was damaged, as was NTPC’s under-construction project on the river Dhauli Ganga near Tapovan, according to an official.
And, according to a source in the defence establishment, it could an attempt to hit the key power project—as a blast in the glacier can be triggered from a distance as well.


DRDO'S Chandigarh-based Snow and Avalanche Study Establishment (SASE) works in avalanche forecasting, artificial triggering and structural control in snowbound mountainous regions. After the recent restructuring of DRDO, it was merged with the Defence Terrain Research Laboratory in and is now called the Defence Geoinformatics Research Establishment.

A DGRE team will be moved to the accident side by IAF helicopters to study the event.

Payback for Gayari? This Indian lab, among other things, is responsible for “artificial triggering” of avalanches.

I don't think it is sabotage. Might be a symptom of global warming.

For a "defense expert" who admitted that he has not studied such incident in the last 50 years, to make a statement that said "To my understanding, glacier burst in this season is next to impossible" is hilarious.

Winter of 1941
A flood caused by a glacial lake outburst flood on December 13, 1941 killed an estimated 1,800 people along its path in Peru, including many in the town of Huaraz. The cause was a block of ice that fell from a glacier in the Cordillera Blanca mountains into Lake Palcacocha. This event has been described [10] as a historic inspiration for research into glacial lake outburst floods. Numerous Peruvian geologists and engineers created techniques for avoiding such floods and exported the techniques worldwide.

A glacial lake outburst flood (GLOF) is a type of outburst flood that occurs when the dam containing a glacial lake fails. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup. The dam can consist of glacier ice or a terminal moraine. Failure can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake or cryoseism, volcanic eruptions under the ice, or massive displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it.
