On #mountain slopes, we previously found strong feedbacks between #geomorphic processes, #landforms and #plants. But what about #sediments? Do they matter for #biogeomorphic feedbacks? If yes, which sediment properties should we measure and how? Have a look! onlinelibrary.wiley.com/doi/10.1002/...

Why sediments matter for mountain biogeomorphology

Grain size distributions, sediment and soil chemistry control feedback between plants and geomorphic processes across alpine hillslopes. With our developed workflow, this key sedimentological data ca...

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. www.nationalgeographic.com/environment/...

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? eos.org/thelandslide...

What an inaugural post on bsky.app. A (the) major glacier collapse at Bichgletscher/Kleines Nesthorn.

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. @uugeo.bsky.social #glacier #rockfall doi.org/10.1016/j.ge...

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. Prepint: ssrn.com/abstract=513... #IYGP #VanishingGlaciers #WorldGlaciersDay

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. tc.copernicus.org/articles/18/28

Our new paper shows that Holocene warming increases erosion in Alpine rockwalls on the short-term but decreases mountain erosion on the long-term. doi.org/10.1016/j.ep... #landslides #glacier #permafrost #weathering #rockfall
