The surprising phenomenon was first categorized as an “unidentified seismic event” before the cause was found.
The tsunami in the fjord was triggered by an enormous landslide, a researcher told the French news agency AFP on Friday.
25 million cubic meters of rock fell into the remote Dickson Fjord last September, in an uninhabited area almost 200 kilometers from the sea. That led to a 200-metre-high tsunami at the epicenter, according to the report published in the research journal Science.
The massive wave then rocked back and forth in the remote Dickson Fjord in eastern Greenland for days.
– The unique thing about this event is how long the seismic signal lasted, and how constant the frequency was, says one of the authors of the report in Science, Kristian Svennevig from the National Geological Survey for Denmark and Greenland (GEUS).
The seismic signals were observed globally as far as Antarctica, he says. 70 kilometers away, 4 meter high tsunami waves destroyed a research base on the island of Ella.
The collapse was caused by the thinning of the glacier at the base of the mountain, a process accelerated by climate change, according to the report.
– As the Arctic continues to get warmer, we can expect that the frequency and extent of such events will increase in the future, says Svennevig.

Tsunami in Remote Greenland Fjord Caused by Massive Landslide, Researchers Discover
Unprecedented Seismic Event in Eastern Greenland Stuns Scientists
In a surprising phenomenon that has left scientists stunned, a massive landslide in a remote fjord in eastern Greenland triggered a tsunami that rocked the area for days. The extraordinary event, initially categorized as an “unidentified seismic event,” has been extensively studied and reported in the renowned research journal Science.
The Landslide that Triggered the Tsunami
On September last year, an enormous landslide occurred in the Dickson Fjord, a remote and uninhabited area approximately 200 kilometers from the sea. The landslide, which involved the collapse of 25 million cubic meters of rock, sent a massive wave crashing into the fjord. According to researchers, the resulting tsunami wave reached an astonishing 200 meters in height at its epicenter.
Unprecedented Seismic Signal Lasts for Days
What makes this event truly remarkable is the duration and consistency of the seismic signal. “The unique thing about this event is how long the seismic signal lasted, and how constant the frequency was,” notes Kristian Svennevig, one of the authors of the report in Science. The massive wave rocked back and forth in the fjord for days, generating a seismic signal that was unlike anything seen before.
Researchers Stunned by the Scale of the Event
The research team, consisting of experts from the University of Copenhagen and the Geological Survey of Denmark and Greenland (GEUS), was astonished by the scale of the event. “We were surprised by the sheer size of the landslide and the resulting tsunami,” Svennevig explains. ”It’s not often that we see an event of this magnitude in such a remote area.”
Implications for Our Understanding of Tsunamis
This unprecedented event has significant implications for our understanding of tsunamis and their triggers. While tsunamis are often associated with earthquakes, this event highlights the potential for landslides to generate massive waves that can have devastating consequences.
Eastern Greenland: A Region of Geological Importance
Eastern Greenland is a region of significant geological importance, with its unique combination of glacial and tectonic activity making it an ideal location for studying natural phenomena. The research team’s findings not only shed light on the region’s geological processes but also underscore the importance of continued monitoring and research in this area.
Conclusion
The discovery of the massive landslide-triggered tsunami in eastern Greenland serves as a powerful reminder of the awe-inspiring forces that shape our planet. As scientists, we are constantly learning more about the complex and dynamic systems that govern our world. This remarkable event is a testament to the importance of continued research and exploration, and we can only imagine what other secrets this remote and unforgiving region holds.
