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 ...
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.
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 ...
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 ...
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 ...
Arizona is also one of the Four Corners states and is diagonally adjacent to Colorado. Arizona has a total area of 113,998 square miles (295,253 km 2), making it the sixth largest U.S. state. [1] Of this area, just 0.3% consists of water, which makes Arizona the state with the second lowest percentage of water area (New Mexico is the lowest at ...
