Movement of the Joshimath landslide in India
A new paper (Dalal et al. 2025) in the journal Engineering Geology examines movement of a major landslide complex in India. It shows that the slope reactivated in 2018, probably as a result of the loss of vegetation and poor management of water. Loyal readers will remember a series of posts that I made back […]

New satellite imagery of the 11 May 2024 tailings failure at Siana in Surigao del Norte, Philippines
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. Just under a month ago, I wrote about the tailings failure at the Siana gold mine in Surigao del Norte, Philippines. Capella Space captured good radar imagery of the site. We now […]
