On the International Day of Disaster Risk Reduction, I take this opportunity to highlight one of the most critical and growing risks in the Himalaya, Glacial Lake Outburst Floods (GLOFs). These instantaneous floods occur when the damming moraine of proglacial lake fails. +

The first detailed assessment of supra-glacial debris cover for the entire Greater Caucasus based on DebCovG-carto toolbox and Sentinel 1–2 imagery has now been published in @Geosciences_OA ❄️🏔️

#BirendraLake outburst as viewed from @planet images. Probable ice failure zone and probable avalanche runout paths in the frontal region of #ManasluGlacier.
Paper alert!!!! Alpine glaciers will lose at least a third of their volume by 2050, whatever happens...
If the trend observed over the last 20 years continues at the same rate, almost half the volume of ice will be lost

💡Know your hazards:
🟤The term glacial lake outburst flood (GLOF) refers to the catastrophic release of a water reservoir that has formed at the site of a glacier.

Glacier thinning is not restricted anymore to the low elevation tongues in the Alps. During mass balance year 2021-22, the highest elevations (up to the Mont-Blanc summit) were seriously impacted by low accumulation and multiple heat waves.

A seemingly moderate drainage of the lake as viewed from @planet images. That said the hazard cascades here including proglacial lakes with plenty of associated permafrost (patterned ground) and moraine pose huge risk to downstream communities and infrastructure.
Mass movements along the failure zone (top left of the lake) around #southlhonaklake#sikkim have not ceased yet and will continue in all likelihood for some time. This needs continuous space-based, airborne and in situ monitoring

Some perspectives on the #sikkimflood disaster:
1. A landslide of waterlogged lateral moraine triggered the GLOF.
2. As at Chamoli, the landslide moved tens of m prior to collapse.
3. Anthropogenic activity influenced both the consequences and the triggering of this disaster.

Three happy scientists on a glacier.
Parth Sharma, myself and @glacioverse (left to right).
We are on Drang Drung Glacier in Zanskar, India. Happy after a very successful day of science, working with @irfansalroo ‘s team.
