Landslides during periods of glacial retreat in Alaska
An excellent new paper (Walden et al. 2025) examines the occurrence of accelerated movement in rock slope landslides in Alaska as adjacent glaciers melt. The exceptional temperatures in recent days in both North America and Europe has once again highlighted the rate at which the climate is changing in response to anthropogenic increases in greenhouse […]

The 26/27 May 2025 update on the landslide threatening Blatten in Switzerland
Smaller rockfalls have reduced the risk of a major rock slope collapse above Blatten, but attention has shifted to the Birch Glacier, which is now moving at 10 metres per day. The Landslide Blog is written by Dave Petley, who is widely recognised as a world leader in the study and management of landslides. Over […]
