'Unidentified Seismic Object' Shook Earth for Nine Days–Now We Know What It Was
In September 2023, a massive landslide in Greenland caused a 200-meter-high mega-tsunami, highlighting climate change's impact on geological stability and prompting a reevaluation of scientific methodologies to address such events.

In September 2023, scientists detected an unusual seismic signal that was traced back to a massive landslide in Greenland's Dickson Fjord. This landslide, which involved a significant volume of rock and ice, triggered a 200-meter-high mega-tsunami and a prolonged seiche that lasted for nine days. The event was unprecedented, as the tsunami's height surpassed that of previous major tsunamis, such as those in Indonesia and Japan. The research, published in the journal Science, involved collaboration among 66 scientists from 40 institutions across 15 countries. The landslide was attributed to decades of climate change, which had weakened the glacier and destabilized the mountain above it. This incident highlights the growing impact of climate change on geological stability, suggesting that similar events may occur more frequently as permafrost thaws and glaciers recede. The findings challenge existing scientific frameworks and emphasize the need for new methodologies to understand and respond to these emerging phenomena. As climate change continues to reshape the planet, the scientific community must adapt to these unexpected geological events, which have global implications.
- A massive landslide in Greenland triggered a 200-meter-high mega-tsunami in September 2023.
- The tsunami generated a unique seismic signal that lasted for nine days, unprecedented in recorded history.
- The event underscores the impact of climate change on geological stability, with expectations of more frequent occurrences.
- Collaboration among international scientists was crucial in analyzing and understanding the event.
- Existing scientific methods may need to be revised to address the challenges posed by climate change-induced geological phenomena.
