Sikkim has identified 40 high-hazard glacial lakes, with 16 at the highest risk of catastrophic outbursts. Following a devastating GLOF in 2023, the state is developing India's first dedicated GLOF Risk Mitigation Protocol, using advanced monitoring and interdisciplinary approaches to protect downstream settlements and serve as a model for other Himalayan regions.
A new scientific report reveals that the recent devastating floods in Nepal's Bhotekoshi-Trishuli corridor were triggered by a massive ice-rock avalanche from the high Himalayas, challenging initial assumptions of rainfall or glacial lake outburst floods.
Villages along the Uttar Pradesh-Bihar border are on high alert following devastating flash floods in Nepal, with authorities monitoring the Gandak River for potential downstream surges and the NDRF deploying 20 teams for preparedness.
China on Friday said the collapse of a high-altitude glacier in Nepal may have triggered the massive flash flood disaster that engulfed the Tibet-Nepal border, killing hundreds and causing widespread damage.
Scientists are examining how a possible glacial collapse and ice-rock avalanche may have triggered the devastating flash floods along Nepal's Bhote Koshi River, with preliminary assessments indicating that debris may have temporarily blocked the Lhende River and created a landslide dam that subsequently gave way.
Following devastating flash floods in Nepal, experts are calling for systematic scientific assessments of glaciers to understand and mitigate hazards, alongside the development of a robust land use policy for the Himalayan region. The floods, which killed over 460 people and left thousands missing, are believed to be linked to climate change impacts on glaciers and permafrost.
A team of scientists has identified a 'potentially dangerous' proglacial lake at 16,500 feet in Arunachal Pradesh's Mago Chu basin, a critical headwaters region of the Brahmaputra, warning of a possible Glacial Lake Outburst Flood (GLOF) due to rapid glacier transformation.
A comprehensive risk assessment warns that Kishtwar district in Jammu and Kashmir faces a serious threat from glacial lake outburst floods (GLOFs), endangering lives, infrastructure, and the ecosystem. The report calls for immediate mitigation measures and long-term strategies to build resilience.
'What we are witnessing is not a freak incidence or a freak occurrence, but a new climate reality where warming oceans, monsoon variability and local geography are combining to produce extreme events.'
A GLOF occurred in parts of Lhonak Lake, leading to a rapid rise in water levels with very high velocities downstream along the Teesta River Basin in the early hours of October 4. This resulted in severe damage in Mangan, Gangtok, Pakyong and Namchi districts.
A study by an international team of researchers had warned two year ago that the South Lhonak lake in Sikkim may burst in the future and significantly impact the downstream region.
The study by an international team led by scientists at the UK's Newcastle University is the first global assessment of areas at greatest risk of Glacial Lake Outburst Floods (GLOF). Published in the journal Nature Communications on Tuesday, it estimates that 15 million people around the world are at risk from flooding caused by glacial lakes.
The NRSC satellite imagery revealed that the lake covered approximately 162.7 hectares. Its area increased to 167.4 hectares on September 28 but drastically reduced to 60.3 hectares.
'The Weather Channel argues that India faces the gravest challenge: Climate change-induced health vulnerability.' 'This is an issue often neglected, alerts Claude Arpi: "Prolonged summers, unpredictable rains, floods, droughts, and rising sea levels are the harsh realities of climate change in the country. These factors increase the frequency and severity of illnesses, pushing people into poverty, and forcing migration".'
Sikkim Chief Minister Prem Singh Tamang, better known as P S Golay, on Friday said that the Himalayan state has incurred damages worth thousands of crores of rupees in the flash flood.
A dozen teams of the NDRF will be deployed to ensure the safety of the people who embark on the yatra from July 1, they added.
Glaciers in the Karakoram region are in a stable condition, but those feeding the Ganga and the Brahmaputra river basins are melting at a faster rate, the earth sciences ministry has said.
'We need an early warning system in India.'
To avert another Uttarakhand-type catastrophe, we must change course. We should stop pandering to the Indian elite's insatiable appetite for electricity, which is driving reckless dam construction, says Praful Bidwai
