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.

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 ...
Engabreen Glacier in Norway extended to within 7 m (23 ft) above sea level in 2014, the lowest altitude of any glacier in Europe outside Svalbard. During the 20th century it reached the water. In the Spanish Pyrenees, recent studies have shown important losses in extent and volume of the glaciers of the Maladeta massif during the period 1981–2005
The pyrenees have a lot of small glaciers that have stopped moving or haven't been studied since becoming very small. For example, in the Monte Perdido masif there were many more glaciers, like the Grieta, the La cascade, the Marboré, the Paillas (two glaciers), and the Astazou.
Glacial loads provided more than 30 MPa of vertical stress in northern Canada and more than 20 MPa in northern Europe during glacial maximum. This vertical stress is supported by the mantle and the flexure of the lithosphere. Since the mantle and the lithosphere continuously respond to the changing ice and water loads, the state of stress at ...
