Landslides from the 3 November 2025 Afghanistan earthquake
Some videos have emerged from Afghanistan this morning, reportedly showing landslides and rockfalls triggered by the M=6.3 earthquake. At 12:59 am on 3 November 2025 (local time, which is 20:29 UT on 2 November 2025), an M=6.3 earthquake struck near to Mazar-E Sharif in Afghanistan. Initial reports suggest at least 20 fatalities have occurred, but […]

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) […]

How Glacial Forebulges Shape the Seas and Shake the Earth
A glacial forebulge is a bending-related upheaval of the lithosphere that has a strong effect on the sea level change pattern and on lithospheric stresses, which can induce intraplate earthquakes.
