The giant Tupaasat rock avalanche in South Greenland
A new paper describes a rock avalanche in Greenland about 10,900 years BP that had a volume of over 1 billion cubic metres and that travelled almost 16 kilometres. A fascinating paper (Pedersen et al. 2026) has just been published in the journal Geomorphology that describes a newly-discovered ancient rock avalanche in Greenland. This landslide, […]

The 22 May 1960 earthquake-induced landslides and tsunami at Lake Rupanco in Chile
Reconstruction of landslides on the banks of Lake Rupanco in Chile, triggered by the 22 May 1960 Mw-9.5 earthquake, suggests that a slope failure with a volume of 161 million cubic metres triggered a tsunami with a maximum amplitude of 33.3 metres. About 120 people were killed. A very interesting paper (Quiroga et al. 2025) […]
