In the US, large glacial outburst floods have been researched since the 1920s. [1] In the 1980s, Russian geologists discovered large deposits created through similar catastrophic outbursts of Pleistocene giant glacier-dammed lakes in inter-montane basins of the Altai Mountain range. [2]
Already, an estimated 10 million people are at risk of glacial outburst floods in Iceland, Alaska and Asia — a phenomenon already occurring as meltwater collapses ice dams and rapidly floods ...
A jökulhlaup is thus a sub-glacial outburst flood. Jökulhlaup is an Icelandic term that has been adopted into the English language, originally referring only to glacial outburst floods from Vatnajökull, which are triggered by volcanic eruptions, but now is accepted to describe any abrupt and large release of sub-glacial water.
The Kathmandu Valley received between 240 millimetres (9.4 in) and 322.2 millimetres (12.69 in) between 28 and 29 September, causing flooding in Nepal's capital, Kathmandu. In late September, the Government of Nepal reported at least 224 deaths, 158 injuries, 28 missing persons due to severe flooding, including at least 37 in Kathmandu. Around ...
As glaciers melt and pour massive amounts of water into nearby lakes, 15 million people across the globe live under the threat of a sudden and deadly outburst flood, a new study finds. More than ...
Finally, Lake Agassiz was an immense glacial lake located in the center of North America. Fed by glacial runoff at the end of the last glacial period, its area was larger than all of the modern Great Lakes combined, and it held more water than contained by all lakes in the world today. It drained in a series of events between 13,000 BP and ...
The bursting of such snow-and-ice dams is a phenomenon called a jökuhlaup, and while it’s relatively little-known in the U.S., researchers say such glacial floods could threaten about 15 ...
In geomorphology, an outburst flood—a type of megaflood—is a high-magnitude, low-frequency catastrophic flood involving the sudden release of a large quantity of water. [1] [2] During the last deglaciation, numerous glacial lake outburst floods were caused by the collapse of either ice sheets or glaciers that formed the dams of proglacial ...
