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.
Altogether 14 glacial lake outburst floods (GLOFs) [19] occurred between 1935 and 1991. In total, 21 GLOFs [20] have been identified as being potentially dangerous at present. In this way, CC and livelihoods integral part and have vice versa relationship. The low income and subsistence users are about 38% of total population.
The rising temperatures since 9 August, which peaked at 15 °C (59 °F) on the day of the flood, contributed to the outburst. [9] The sudden flood displaced 135 people, including 40 children. Most residents had already left for Kathmandu or were at the weekly marketplace in Namche. Because the school was closed for the day, no students were hurt.

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 ...
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 ...
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 ...
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 ...
