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 ...
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.
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 ...
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 ...
The term "megatsunami" has been defined by media and has no precise definition, although it is commonly taken to refer to tsunamis over 100 metres (330 ft) high. [2] A megatsunami is a separate class of event from an ordinary tsunami and is caused by different physical mechanisms.
A tsunami stemming from a landslide was behind a surprising seismic event last year that shook the earth for nine days, researchers said.
