A jokulhlaup -LRB- -LSB- ˈjœːkʏløip -RSB- -RRB- -LRB- literally ` glacial run ' -RRB- is a type of glacial outburst flood .. glacial. glacial. outburst flood. outburst flood. It is an Icelandic term that has been adopted in glaciological terminology in many languages .. Icelandic. Icelandic language. glaciological. glaciology. It originally referred to the well-known subglacial outburst floods from Vatnajokull , Iceland , which are triggered by geothermal heating and occasionally by a volcanic subglacial eruption , but it is now used to describe any large and abrupt release of water from a subglacial or proglacial lake / reservoir .. Vatnajokull. Vatnajokull. Iceland. Iceland. subglacial eruption. subglacial eruption. subglacial. subglacial lake. proglacial lake / reservoir. Proglacial lake. Since jokulhlaups emerge from hydrostatically-sealed lakes with floating levels far above the threshold , their peak discharge can be much larger than that of a marginal or extra-marginal lake burst .. discharge. discharge ( hydrology ). The hydrograph of a jokulhlaup from Vatnajokull typically either climbs over a period of weeks with the largest flow near the end , or it climbs much faster during the course of some hours .. Vatnajokull. Vatnajokull. hydrograph. hydrograph. These patterns are suggested to reflect channel melting , and sheet flow under the front , respectively .. Similar processes on a very large scale occurred during the deglaciation of North America and Europe after the last ice age -LRB- e.g. , Lake Agassiz and the English Channel -RRB- , and presumably at earlier times , although the geological record is not well preserved .. deglaciation. deglaciation. last ice age.
