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 ...

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]

Dialect was developed by linguists Hakan Seyalioglu and Kathryn Hymes, who crowdsourced money for publication via Kickstarter. [4] Seyalioglu connected the game to his experiences as a Turkish speaker in the United States, and Hymes described the game's theme of language as the basis of community, saying "Language is powerful — it's how we interact with each other …
The drainage of supraglacial lakes on mountain glaciers can disrupt the internal plumbing structure of the glacier. Natural events such as landslides or the slow melting of a frozen moraine can incite drainage of a supraglacial lake, creating a glacial lake outburst flood. In such a flood, the lake water releases rushes down a valley.
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.
