#Legambiente presenta il VI report Carovana dei #Ghiacciai

>> Le #Alpi siano sempre più fragili e instabili, con 40 eventi franosi documentati in alta quota, soprattutto crolli di roccia e colate detritiche per il solo 2025. Tra i casi simbolo: la valanga di roccia e ghiaccio di #Blatten in #Svizzera e le ripetute colate detritiche sull’ #Alemagna (BL). Ma in aumento sono anche gli eventi #meteo estremi: 154 quelli mappati in questi 11 mesi dell’anno in corso dall’Osservatorio Città #Clima di Legambiente nelle regioni dell’arco alpino.

New models improve predictions of snow, rock and ice avalanches

A new 3D simulation tool developed by ETH and SLF researchers now allows for significantly more accurate predictions of complex alpine mass movements, supporting alpine risk management.

The model produces the most accurate simulation of the disaster in Blatten.

Ähnlich grosser Abbruch wie in Blatten nicht ausgeschlossen

In einem Informationsschreiben teilt die Gemeinde Kandersteg mit, dass ein grosser Abbruch am Spitze Stei nicht ausgeschlossen ist, aber zum Restrisiko gehört. Murgänge sind wahrscheinlicher.

After what happened in Blatten, it might be good to be reminded of the situation near Kandersteg with the "Spitze Stei" (Pointy Rock).

To start with: currently there is NO acute risk of rockslides and the situation it NOT directly comparable with Blatten.

What is comparable though, is that fact the the instability of the mountain is most likely related to the thawing of permafrost. Where in Blatten 3-5 million cubic meters came down, the Spitze Stei area that is moving is approx 16 million cubic meters in size. There is no glacier involved where the rocks might fall on as in Blatten, but the debris flow might cause a flooding of Lake Oeschinen, which poses a risk for the village of Kandersteg downstream.

I'm not trying to cause panic, the situations are not directly comparable and there is no indication things are speeding up (currently moving with approx 0.4 cm per day). It does however show that instability of mountains because of thawing of permafrost is a broader phenomenon than "just" Blatten.
