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 […]
The 22 July 2021 Xiao Dongsuo debris flow on the Tibetan Plateau
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. Debris flows in arid and semi-arid areas are less common than in more humid environments, but they can have devastating consequences. There has been considerably less research into these processes than might […]
