Greenland Landslide Sparks Nine-Day Global Seismic Shocks

A landslide in Greenland, driven by glacier melting due to climate change, triggered a nine-day global seismic tremor. The September 2023 collapse of a mountain in an East Greenland fjord caused a 200-meter tsunami. Researchers suggest climate change is behind this phenomenon, warning of increased future landslides.

A recent landslide in Greenland, induced by glacier melting due to climate change, has triggered a seismic wave that reverberated globally for nine days. This event damaged infrastructure and baffled scientists worldwide, according to a new study.

In September 2023, a 1.2-kilometer high mountain in an East Greenland fjord collapsed, generating a towering 200-meter tsunami. The seismic shocks from this event sent researchers scrambling to understand the mechanics behind this unusual occurrence.

Using a combination of mathematical models, field measurements, and satellite imagery, an international team of scientists revealed that the ongoing sloshing of water in the fjord resulted in the lengthy seismic activity. The study underscores the cascading impacts of climate change on Earth's natural systems.
