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) […]
