Alps rockfalls linked to thawing permafrost and increasing geological instability

A series of significant rockfalls has occurred in the Alps, specifically affecting the Zugspitze on the German-Austrian border and Gross Ruchen in Switzerland. At the Zugspitze, an unusual large-scale rockfall on the Tyrolean north face released approximately 13,800 cubic meters of rock at an altitude of 2,800 meters, creating large dust clouds and ongoing instability. Experts and researchers from the Technical University of Munich are investigating the event, noting that temperatures at the nearby Kammstollen have risen from -1.2 to -0.7 degrees Celsius since 2007. In Switzerland, a separate collapse at Gross Ruchen in the canton of Uri saw roughly 2,000 cubic meters of rock break off from the north face at an altitude of 2,900 meters. This event produced a massive dust cloud that reached the Reusstal and Brunnital valleys. No injuries or damage to infrastructure were reported in Unterschächen. Authorities and researchers have linked these geological events to thawing permafrost, which serves as a natural adhesive for rock formations. It is suggested that rising temperatures and extreme heat may be melting frozen water within the rocks, compromising structural stability. These incidents appear to be part of a broader trend of instability across the Alps, with increased rockfalls also being recorded in the Dolomites and Mont Blanc. Furthermore, Swiss glaciers have experienced significant ice loss, with some areas losing nearly 20% of their volume since 2021 due to heatwaves and low snowfall. Recent warnings have emerged regarding Mount Hochvogel in the Allgäu Alps on the German-Austrian border. Scientists estimate a potential rockslide of between 250,000 and 400,000 cubic meters. A long-standing fissure has widened significantly, with researchers describing a main crack up to six meters wide, 35 meters long, and 60 meters deep.
