A looming rock collapse threatens a Swiss village as thawing permafrost destabilizes the Alps
- An unstable rock formation called Spitze Stei is threatening the Swiss village of Kandersteg with a possible landslide.
- Scientists say thawing permafrost and melting glaciers are making mountain slopes in the Alps less stable as temperatures rise.
- Kandersteg has about 1,300 residents and sits below steep mountain terrain in Bern canton.
- Local authorities are monitoring the rock formation continuously and have evacuation plans in place.
- Residents said they are aware of the risk but noted that precautions have been taken and the situation is being watched closely.
An unstable mountain rock formation above Kandersteg, Switzerland, is raising concern about a possible landslide that could threaten the village below. The formation, called Spitze Stei, sits in an Alpine landscape that is increasingly affected by warming temperatures and the loss of frozen ground that helps stabilize mountain slopes.
Scientists cited in the report say climate change is melting glaciers and permafrost across the Swiss Alps. Because ice in mountains and loose debris can act like a binding agent, its disappearance makes slopes more prone to collapse. The article notes that a similar disaster hit the nearby Blatten valley in 2025 after rock and ice broke loose from a glacier.
Kandersteg has around 1,300 residents, and local officials are closely monitoring the site. Evacuation plans are already prepared, and residents quoted in the article said they are aware of the danger but are trying to live normally under the circumstances.
The report says the unstable section of Spitze Stei is estimated at about 15 to 20 million cubic meters. While experts are watching the area carefully, the threat reflects a broader pattern of rising landslide risk in the Alps as glaciers and permafrost continue to thaw.
阿尔卑斯山永久冻土融化导致山体不稳，瑞士一座村庄面临岩体坍塌威胁
瑞士卡德尔斯泰格村上方一处不稳定山体岩块正在引发担忧，可能会发生山体滑坡并威胁山下村庄。该岩体名为“Spitze Stei”，位于阿尔卑斯山环境中，而这里正因气温升高和冻结地层减少而变得更加不稳定。
报道援引的科学家表示，气候变化正在使瑞士阿尔卑斯山的冰川和永久冻土持续融化。山体中的冰和松散碎屑原本起到类似黏合剂的作用，一旦消失，山坡就更容易失稳。文章提到，邻近的布拉滕谷地曾在2025年发生类似灾害，岩石和冰块从冰川上方崩落。
卡德尔斯泰格约有1300名居民，当地政府正在对该区域进行密切监测。疏散方案已经准备就绪，文中受访居民表示，他们意识到风险，但仍尽量在这种情况下正常生活。
报道还称，Spitze Stei中不稳定部分的体积估计约为1500万至2000万立方米。尽管专家正持续观察，但这一威胁也反映出随着冰川和永久冻土继续融化，阿尔卑斯山区山体滑坡风险正在上升。
