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 ...
That destabilized a steep mountainside, sending a rock and ice avalanche crashing into Greenland’s deep Dickson Fjord. That displaced a massive volume of water, so a towering wave traveled ...
A colossal rockslide that triggered a mega-tsunami caused the Earth to ‘hum’ for days, ... triggered a massive tsunami in Dickson Fjord, creating puzzling tremors and a planet-wide “hum ...
The subsequent mega-tsunami — one of the highest in recent history — set off a wave which became trapped in the bendy, narrow fjord for more than a week, sloshing back and forth every 90 seconds.
High mountains surround Dickson Fjord, and its shores are very steep. The head is located in the isthmus area of Suess Land , only about 6 kilometres (3.7 mi) south of the head of Kjerulf Fjord . The northern shore of the fjord is part of Suess Land, and the southwestern of Gletscherland , where the highest point, about 2,194 m (7,198 ft) high ...
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 height. A 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 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 ...
