On September 16, 2023, a massive landslide occurred in Dickson Fjord, northeastern Greenland. It was triggered by a series of factors, including the glacial debuttressing due to climate change . Greenland, being highly sensitive to rising temperatures, has experienced accelerated glacial retreat and destabilization in recent years, making ...
On 16 September 2023, a significant landslide, consisting primarily of ice and rock, occurred in Dickson Fjord, triggering a 200-meter-high tsunami. However, the tsunami was not immediately observed due to a seiche formation. A seiche is a standing wave oscillating back and forth within a confined body of water, such as a fjord.
The landslide, which took place last year in September, triggered a massive tsunami in Dickson Fjord, creating puzzling tremors and a planet-wide “hum”, scientists said.

Because this is a recently deglaciated fjord with steep slopes and crossed by a major fault (the Fairweather Fault), one possibility was that this wave was a landslide-generated tsunami. [ 17 ] On 9 July 1958, a 7.8 M w strike-slip earthquake in southeast Alaska caused 80,000,000 metric tons (90,000,000 short tons) of rock and ice to drop into ...
A 650-foot tsunami in Greenland was the result of melting glacial ice that caused a landslide. The waves it created bounced back and forth for nine days.
The investigation (involving 68 scientists, 40 institutions, and 18 countries) eventually revealed that the likely culprit was a rockslide in Dickson Fjord, located on the central east coast of ...
