(1) a large outburst flood that usually occurs when a glacially dammed lake drains catastrophically (2) any catastrophic release of water from a glacier.
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-damm
ed lakes in side valleys. Also known as 'glacial outburst floods'. 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.
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 (Icelandic). (from the Icelandic). A sudden an
d often catastrophic outburst of water from a glacier during a volcanic eruption. The term is also used to describe when an ice-dammed lake bursts or an internal water pocket escapes, resulting in flooding.
