On September 16th, 2023 at 12:35 UTC, a 25.5 Mm 3 (3.34 × 10 19 cu yd) rockslide occurred on the slope of Dickson Fjord in Northeast Greenland. [ 1 ] [ 2 ] The rockslide impacted a gully glacier, leading to a rock and ice avalanche that entered the fjord causing an up to 200 m (660 ft) high tsunami and subsequent waves up to 110 m high, with ...
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. ... deep Dickson Fjord. That displaced a ...

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 July 9, 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 ...
On 16 September 2023 a large landslide originating 300–400 m (980–1,310 ft) above sea level entered Dickson Fjord, triggering a megatsunami exceeding 200 m (660 ft) in run-up. Run-up of 60 m (200 ft) was observed along a 10 km (6.2 mi) stretch of coast forming a seiche oscillation that decayed over a period of 9 days. [211] [212] 2024 Japan
A tsunami stemming from a landslide was behind a surprising seismic event last year that shook the earth for nine days, researchers said. Mysterious 9-day seismic event triggered by 650-foot ...
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.
