In 2023, two enormous mega-tsunamis rocked an East Greenland fjord for nine consecutive days, sending seismic waves around the globe. This extraordinary event puzzled scientists until a new generation of satellite technology provided the first direct evidence confirming the cause: colossal landslides triggered by climate change melting glaciers.

A massive landslide in Greenland's Dickson Fjord in 2023 triggered a 200-metre-high tsunami, causing global seismic vibrations for nine days.
