A major slope collapse in frozen sediments in Canada highlights the role of progressive failure. Back in January of this year, I posted fascinating a piece by Derek Cronmiller of the Yukon Geological Survey about the 17 December 2024 Takhini River landslide and river-ice tsunami, which occurred in Whitehorse, Yukon, Canada. The location of this […]

The timing of landslides in areas of permafrost thawing
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. There is a no scientific doubt that human activity is driving rapid warming of the terrestrial climate, and that this is amplified in high latitude and high mountain environments. An inevitable, and […]
