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 began when a 1.2km-high mountain peak collapsed into the fjord, unleashing a 200m-tall wave through the narrow waterway. ... Earlier studies have found that the Greenland ice cap is ...
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.
Natural causes of landslides include: increase in water content (loss of suction) or saturation by rain water infiltration, snow melting, or glaciers melting; [ 10 ] rising of groundwater or increase of pore water pressure (e.g. due to aquifer recharge in rainy seasons, or by rain water infiltration); [ 11 ]
Sea ice loss not only enhances warming in the Arctic but also adds to global temperature increase through the ice-albedo feedback. Permafrost thaw results in emissions of CO 2 and methane that are comparable to those of major countries. Greenland melting is a significant contributor to global sea level rise. If the warming exceeds - or ...
Authors stress that the accelerating loss of ice from Greenland and Antarctica is nonetheless dire. ... He added that even though a rapid collapse was a "low likelihood" scenario in the latest ...
Projected loss of mountain glaciers over the 21st century, for different amounts of global warming. [53] Mountain glaciers are the largest repository of land-bound ice after the Greenland and the Antarctica ice sheets, and they are also undergoing melting as the result of climate change. A glacier tipping point is when it enters a ...
The Greenland Ice Sheet is losing, on average, 30 million tons of ice per hour. Ice loss from the Thwaites Glacier, also known as the “Doomsday” glacier because its collapse could precipitate ...
