Crazy (horizontal) runup from the large landslide into Tracy Arm fjord, SE Alaska. This is 20 km out the fjord and the wave reached up to 400 m into this side valley. notice how the vegetation was only wetted for the most part (pixels still red) and only the mouth of the river is destroyed.

Tour Ronde (3793 m) north face used to be an entirely ice-covered slope not so long ago...! 🧊😰
See the situation this morning (📷 X. Cailhol) and in the 1960s (from famous Rebuffat's book 'les 100 plus belles...')

Copied from AEC post on X: Check out these amazing photos of the Tracy Arm Landslide! Thank you to Jacek Macelko for sharing these images, taken on Tuesday, August 12 from 3,500 ft. The pale triangle of the landslide scar stands out. 🧪⚒️🪨 1/2

A new paper (Kharismalatri, Gomi & Sidle 2025) in the journal Natural Hazards uses the concepts of the inflow angle and the channel gradient to examine the behaviour of large landslides after failure. It show that those two measurements predict the behaviour of most slopes.

Staggering loss of volume o the largest Austrian glacier... still for few days!🔥
When the (now tiny) icefall breaks up, it will no longer be the largest ice imass in Austria!

The #Glacier Loss Day is reached in Switzerland!
From now on all melt that occurs on glaciers until October is unsustainable. This tipping point has only been reached so early in the record-shattering year 2022.
Expect big ice loss due to the prolonged melt season and feedback effects

Several mudslides occurred in Gschnitz on Monday evening! 🌊
100 trapped people from the village and three mountain huts had to be evacuated by helicopter by the Army.
The extent of destruction is enormous.
Events of such intensity are increasing! 😱

A Swiss village was buried under a mountain. This town could be next.
In the past century, scientists have observed more rockfalls and avalanches in the Alps, a looming threat to nearby villages.
