Episode 13: Between stability and collapse – processes of mass movement

We leave no stone unturned: this episode is about gravitational mass movements – from inconspicuous landslides to spectacular rockfalls and landslides, such as the one that recently occurred in the swiss village of Blatten. Michael Lotter explains what drives these processes, what role water, rock type and slope inclination play, and why they are becoming more frequent and dangerous in times of climate change. How does the permafrost in the Alps differ from that in the far north? And how must mountain sports respond to the changes in the mountains? Have a listen!
