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...

Swiss Seimological service reports this event as M=3.1 in a very quick first analysis, Cengalo was M=3.0...

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
