new term Jökulhlaup

[Antonarctica]

Any large and abrupt release of water from a subglacial or proglacial lake/reservoir.

A jökulhlaup (Icelandic pronunciation: ​[ˈjœːkʏl̥øip]) (literally "glacial run") is a type of glacial outburst flood. It is an Icelandic term that has been adopted in glaciological terminology in many languages. It originally referred to the well-known subglacial outburst floods from Vatnajökull, 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.

Jökulhlaups are sudden‐onset high‐magnitude discharges of water and sediment from a glacial source. They occur in virtually all glaciated regions of the world and are most commonly directly sourced from any part of a glacier where water can accumulate into a lake. A jökulhlaup usually occurs because a glacial lake drains rapidly due to failure of an ice dam or moraine dam

@Antonarctica Thanks for the request!

Hi, Pier - Here is the combined GCW version - much the same as above.

Jokulhlaup's (an Icelandic term pronounced Yo-kul-hloips) are sudden outbursts of water released by a glacier. The water may be released from glacier cavities, sub-glacial lakes, and from glacier-dammed lakes in side valleys. A glacier outburst flood resulting from the failure of a glacier-ice-dam, glacier-sediment-dam, or from the melting of glacier ice by a volcanic eruption.

Has synonym glacial outburst flood.

Many thanks @rduerr I"ll weave that in and add the GCW synthesis placehoder.
