The 16 September 2023 landslide on the margin of Dickson Fjord in Greenland
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. There has been quite a stir over the last week regarding a remarkable paper (Svennevig et al. 2024) that was published in the journal Science, describing a series of events that occurred […]
