New open access paper on headwall erosion of a deglaciating cirque in the Swiss Alps. In our study we found that headwall erosion is driven by frost weathering and permafrost rather than glacier induced rockfall.

Recent article and intense photography by #NationalGeographic on #permafrost -related hazards in the Swiss Alps, 2025 - covering the tragedy at #Blatten and potential future failure at #SpitzeStei.

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.

On 28 May 2025, the Birch Glacier in Switzerland catastrophically failed, generating a massive landslide that has partially buried Blatten. So what happens next?

And compared rockfall events to rockfall events from 2016 to 2019 quantified using laserscanning in a previous study.

We found that rockfall is mainly driven by frost weathering processes and permafrost rather than glacier retreat.

We quantified glacier retreat and the Rothorn cirque Glacier showed an increasing glacier area loss with 0.2 %/year for 1850 to 1973, 2 %/year for 1973 to 2011 and up to 3.7 %/year for the period 2011 to 2023.

The Rothorn Glacier is a Alpine cirque glacier that lost 86 % of its size since 1850. As very small glacier are more sensitive to climate warming, its retreat rate of -3.7%/a is much larger than large European Glaciers.

In our new paper, we quantified damage by frost weathering in alpine rocks using microCT. With Veerle Cnudde's team at UGhent, we tested the efficacy of different freeze-thaw cycles. Thanks EXCITE Network for funding.

Our new paper shows that Holocene warming increases erosion in Alpine rockwalls on the short-term but decreases mountain erosion on the long-term.
