A flood caused by a glacial lake outburst flood on 13 December 1941 killed an estimated 1,800 people along its path in Peru, including many in the town of Huaraz. The cause was a block of ice that fell from a glacier in the Cordillera Blanca mountains into Lake Palcacocha. This event has been described as a historic inspiration for research ...
In April 2003, NASA scientists discovered a fissure in the glacier above Lake Palcacocha on Terra satellite images of November 2001. Their warnings reached Peru just two weeks after the staff of the UGRH (Unidad de Glaciologia y Recursos Hidricos) had done some field mapping of Lake Palcacocha, where a moraine rupture had caused a minor flood on 19 March 2003 which the safety constructions ...

Quechua is the second language of Peru, in terms of number of speakers. It is the official language in areas where it is the dominant language, even though from a linguistic point of view, it's a family of related languages. (Ethnologue assigns separate language codes to more than 25 varieties of Quechua in Peru.)
The glacier blocks the river, which backs up into a proglacial lake, which eventually overflows or undermines the ice dam, suddenly releasing the impounded water in a glacial lake outburst flood also known by its Icelandic name a jökulhlaup. Some of the largest glacial floods in North American history were from Lake Agassiz. [3]
Oppose A jökulhlaup and a glacial lake outburst flood are not the same thing. Glacial lake outburst floods occur when a dam containing a glacial lake fails as stated in the article. Jökulhlaups are outburst floods as a result of melting glacial ice from geothermal heating or subglacial volcanic activity. Volcano guy 19:50, 19 July 2014 (UTC)
Giant current ripples are an important feature of the Channeled Scablands in Washington state, U.S., which formed during the Last Glacial Maximum as a result of at least 39 glacial lake bursts, called the Missoula floods, which originated from glacial lakes Columbia in Washington and Missoula in Montana.

A jökulhlaup The impounded lake a month earlier, before the same jökulhlaup. A jökulhlaup (Icelandic pronunciation: [ˈjœːkʏl̥ˌl̥œyp] pronunciation ⓘ) (literally "glacial run") is a type of glacial outburst flood. [1] It is an Icelandic term that has been adopted in glaciological terminology in many languages.
