Swiss residents fear mountain rock formation collapse

Key Points:

• An unstable rock formation called Spitze Stei above the Swiss village of Kandersteg threatens a potential landslide similar in scale to the 2025 disaster in nearby Blatten, linked to thawing permafrost and glacier melt due to climate change.
• The melting of permafrost, which acts as a natural cement holding mountain slopes together, is increasing instability in the Swiss Alps, raising the risk of landslides and rockfalls.
• Authorities in Kandersteg have implemented monitoring and evacuation plans, and residents feel relatively calm, noting that rockfall is a longstanding issue but the current threat is exacerbated by global warming.
• Experts suggest the rock formation is more likely to degrade gradually rather than collapse suddenly, but climate change is expected to increase the frequency and severity of such natural hazards in alpine regions.
• Greenpeace Switzerland warns that ongoing climate change may eventually force the abandonment of some mountain villages due to the high costs and risks associated with protecting infrastructure from landslides and avalanches.
