The wonderful Save the Hills blog has documented the long terms effects on downstream communities of the 4 October 2023 GLOF in Sikkim, India:- eos.org/thelandslidebl… Meanwhile, further information is emerging that demonstrates that the trigger of the GLOF was a landslide.

The Sikkim flood of October 2023: Drivers, causes and impacts of a multihazard cascade | Science science.org/doi/10.1126/sc…

We have just published a paper in Science, led by Ashim Sattar, on the Sikkim GLOF. I'm grateful to have contributed to thisand hope our findings will support the development of more resilient infrastructure and improved hazard mitigation strategies. science.org/doi/10.1126/sc…

Our paper on the 2023 S. Lhonak GLOF & multihazard cascade, out today in Science! This ‘natural’ hazard had the fingerprints of human activity all over it: climate change, glacier retreat, permafrost degradation, and hydropower dam failure. Read here: science.org/doi/10.1126/sc…

Expertly led by Dr. Ashim Sattar, and with a wide team of authors from around the world, this work has pulled together an exceptional range of data to build an understanding of how and why this multihazard cascade occurred – and some clues as to how we might reduce future risk.

As expected, impressive collapse of the Birch Glacier above Blatten yesterday! 🧊❄️🌊 Plus another event last night at 4:am! ⌚ For the first time, some deposits overflowed the avalanche protection dam and stopped 400 m from first houses 🏚️ 🎥 srf.ch/play/tv/news-c…

BREAKING: Massive Glacier Collapse in Blatten, Valais (Switzerland) – May 28, 2025 Over 3.5 million m³ of ice, rock, and snow collapsed from the Birch Glacier, putting 9 million tons of pressure on the glacier. The entire village of Blatten (approx. 300 people) was evacuated in

So sad for all the people who lost their homes today in Blatten, Switzerland 🇨🇭😢

उत्तरकाशी जनपद के धराली गांव में बादल फटने से खीरगंगा में भीषण बाढ़। अब तक 4 की मौत, कई लापता। मलबा घरों में घुसा, घर बह गए, लोगों के लापता होने की आशंका। सेना, पुलिस व SDRF राहत-बचाव में जुटी। #Cloudburst #Monsoon2025 #Uttarkashi

📢🌊#️⃣Dharali disaster, Uttarakhand Himalaya—-Finally, cloud-free satellite imagery has provided crucial evidence explaining the Dharali disaster of 5 August 2025. Shashi Kant Rai #dharali #disaster #uttarakhand

The imagery reveals that the disaster was caused by a classic debris-flow cascade, which devastated the valley and swept away infrastructure, including numerous buildings and a major highway linking to the Gangotri glacier.

The debris flow appears to have originated from destabilized glacial deposits located higher up in the valley, most likely associated with degrading permafrost conditions.

This disaster underscores the growing influence of climate change in high mountain environments, where permafrost thaw and intense precipitation events can destabilize glacial sediments, mobilizing them into destructive debris flows.
