A glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup. The dam can consist of glacier ice or a terminal moraine.
Lake Bonneville was not a glacial lake, but glacial age climate change determined the lake level and its overflow. The first scientific report of a megaflood (Gilbert, 1890) describes this event. [8] The last of the North American proglacial lakes, north of the present Great Lakes, has been designated Glacial Lake Ojibway by geologists. It ...
In four decades, as the glacier retreated 1.9 kilometres (1.2 mi), the lake swelled in size, covering nearly 100 hectares (247 acres) by 2008. [5] It was identified as potentially at risk of causing glacial outburst floods, and in 2018 pipelines were carried up by yak and installed to pump water out of it. [6]
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 ...
The ensuing floods happen with little to no warning and previous glacial lake outbursts have killed thousands of people and destroyed property and critical infrastructure.. A 2020 study of the ...
Raging waters that ate away at riverbanks, destroyed at least two buildings and damaged others had receded Monday in Alaska's capital city after an outburst of weekend flooding from a glacial lake ...
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 ...
