The study presents an inventory of hanging glaciers in the Alaknanda basin (Garhwal Himalaya) and the authors performed runout simulations for select glaciers that could impact infrastructure. Their findings highlight the need for targeted monitoring and risk-informed planning.

The number of fatal landslides each year since 1968 in Nepal. The grey line is a four year retrospective running mean. Author's own dataset.
Since 1968 there have been over 1,400 fatal landslides in Nepal, killing over 6,000 people. The data shows that the impacts are increasing with time.

Registration is open for the 3rd Asian Conference on #Permafrost (ACOP) 2026 in Ulaanbaatar, #Mongolia, from June 28 to July 2, 2026! The conference boasts a rich program, including several sessions on #hazards and #risks of interest to the #gaphaz community!

Have you submitted your #EGU26 abstract?! We‘ve put together a little list (non-exhaustive) of sessions that fit gaphaz topics well. See you in #Vienna

Climate change leads mountain guides in the Alps to alter their choice and timing of high-altitude routes, reacting to increasing danger 🧪 gh.copernicus.org/articles/80/...
A number of #gaphaz members, including glaciologists from #Tajikistan, are investigating a sequence of catastrophic #detachments from #Didal glacier following sudden, #surge like accelerations this summer and fall. Stay tuned for more!

As #COP30 heats up, superb visual storytelling in @nytimes.com about climate change & the threat of glacial lake outburst floods in the Himalaya, featuring the work of @cscottwatson.bsky.social and quotes from @kristencook.bsky.social @sonamshp.bsky.social and me. 🧪⚒️ www.nytimes.com/interactive/...
📘 New paper: Post-Little Ice Age Shrinkage of the Tsaneri–Nageba Glacier System and Recent Proglacial Lake Evolution in the Georgian Caucasus
📉Glacier shrank ~43% since ~1820
🌊Lake grew from ~14,000m² in 2015 to ~107,900 m² 2025

Some good news from space, as the NASA-ISRO NISAR mission publishes its first synthetic aperture radar images of Earth. This spacecraft has a heckin' big antenna (a dish 12 meters across) for bouncing L- and S-band (25- and 10-cm) radio waves off the surface www.jpl.nasa.gov/news/nasa-is...

The Matai’an landslide dam in eastern Taiwan has failed this afternoon (eos.org/thelandslide...), flooding Guangfu, about 15 km downstream focustaiwan.tw/society/2025.... Even in the middle of a typhoon, the resulting flood produced a detectable seismic signal at stations ~40 km away.

We are at #IMC2025 in Innsbruck this week! Be sure not to miss our official #gaphaz session:
FS 3.148 - Glacier and permafrost risks in a changing climate (Wed. 13:30).
Convened by @jane-walden.bsky.social, #Marta-Chiarle and #Mylène-Jacquemart
#GAPHAZ members are well represented at #IMC2025 in #Innsbruck 🏔️ this week and there are several sessions directly related to #glacial and #periglacial #hazards! We will kick things off tomorrow afternoon with a session on #Alpine #Mass #Movements. In SOWI - HS 3!

Excellent compilation of information about the Tracy Arm #landslide and #tsunami in #Alaska ! Check out the information put together by @akearthquake.bsky.social! earthquake.alaska.edu/event/025a7d...

Exciting new NSF-funded initiative to advance knowledge about natural hazards! We look forward to learning more and seeing exciting science coming out of this!
Today marks 60th anniversary of the Mattmark catastrophe, one of the deadliest glacier-related disaster in the Alps and largest catastrophe in Swiss modern history! 🧊🌊
30th Aug 1965: 2 Mm3 of Allalin Gl. broke off on Mattmark dam construction site, killing 88, many of whom were Italian immigrants 😭
Very nice overview of the recent #GLOF in Pakistan by @sgascoin.bsky.social!
There is so much going on these days, it’s great that various people in the community manage to find time to document these events! Fingers crossed that nobody was harmed. www.cesbio.cnrs.fr/multitemp/ra...
My rapid analysis of the recent GLOF (?) in Gupis, Gilgit-Baltistan www.cesbio.cnrs.fr/multitemp/ra...
Just when we thought NISAR would always „launch in two years“ it is finally here! Among other, it will provide valuable data on ground displacement to better understand and forecast landslides, also in high-mountain regions! Congrats to all involved!!

Nice one @geophysichick.bsky.social! How far in advance did you register these?
Juneau officials say new flood-control barriers are holding, making for far less damage than during last year’s destructive glacial outburst from Suicide Basin.
There are a tremendous number of icebergs in Tracy Arm following the landslide-triggered tsunami. The reason for this is that ~300 meters of the north side of South Sawyer Glacier broke off and disintegrated into many many smaller icebergs as seen in @planet.com imagery 🧪⚒️
Congrats Caroline! Good luck in your new role!

It is likely that a large, tsunamigenic landslide occurred in Tracy Arm inlet, in Alaska on 10 August 2025 at 5:30 am.

First cloud-free optical satellite imagery from @planet.com show the destruction of Dharali village in Uttarkashi, Uttarakhand, India. Unfortunately the source area in the mountains is still obscured by cloud and so the ultimate cause is still speculative. 🧪⚒️
Wow! That is really impressive indeed! 😱Hopefully nobody was in harm’s way?
Congrats!!!
