My sincere thoughts to those on the #Nepal / #Tibet #border so very affected by the recent (#climatechange-related) #glaciallakeoutburstflood (#GLOF) downstream affects (with a seeming #earthquake geotechnical failure trigger)

The #deaths of your #family, #friends & #colleagues – and ‘things’ – must be so very hard!
May the #missing individuals return safely. 🙏

EDIT: Reading that ~100 million cubic metres of debris-laden water came down Nepal's Bhote Koshi valley; even as geologist familiar with 'non-human' time scales and a 'kinda-hydrologist-via-osmosis', that is simply an incomprehensible amount!

🌊 Nepal #FlashFlood | When #Mountain #Hazards #Cascade
The devastating flash #flood in Nepal is more than a flood story—it is a lesson in how interconnected the #Himalayan environment really is.
Preliminary assessments indicate that an #ice #rock #avalanche likely blocked the #LhendeKhola, causing #water to build up and then surge downstream into the #BhotekoshiRiver system. Scientists are still investigating the exact chain of events, including whether recent #seismic activity contributed to the slope failure. (The Kathmandu Post)

[Note - updated post with different images(s) as some commentators with their #wellactually approaches and puerile agendas are suggesting some of the images are AI-generated; these ones are confirmed from reputable places (Reuters, NBC in the USA, etc); sorry for any confusion - but NOT technical inaccuracies - in these posting(s)]

H/T @abhinav Alangadan
“Can we develop a first-order understanding of permafrost degradation and glacial lakes exposed to degradation-induced mass movements in the Himalaya?
[The authors] tried to address this question. The study [first link above] integrates machine learning, statistical modeling, and numerical modeling to investigate high-resolution permafrost distribution, potential degradation, and associated mass-movement hazards in the Kinnaur district of Himachal Pradesh, India.
Using rock glaciers as proxies, [they] generated a high-resolution permafrost distribution using machine learning, while potential degradation zones were delineated using the 0°C isotherm as a first-order indicator. [They] further identified glacial lakes located near potentially degrading permafrost zones and reconstructed their bathymetry. A detailed scenario-based GLOF process-chain simulation was then carried out for Kashang Lake using r.avaflow and HEC-RAS.
[Their] results indicate that seven glacial lakes in #Kinnaur are located close to potentially degrading permafrost zones. The simulations further show that a potential GLOF from Kashang Lake could inundate critical downstream infrastructure, including nearly 11 km of National Highway 5…”

Glacial lake outburst flood (Volcanology 🌋)

A glacial lake outburst flood is a type of outburst flood caused by the failure of a dam containing a glacial lake. 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...
