Short summary

The 2024 Platteikogel rock slope failure (Tyrol, Austria) highlights how cryospheric changes promote slope failure. We demonstrate how the system feedback of ice apron loss, permafrost warming, increase in rockfall activity, and changes in groundwater conditions accelerate mechanical destabilization, and as a consequence likely peaked in the observed failure. Today, rapidly vanishing ice aprons potentially mark source zones for future rock slides.
