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 ...
This meant Palcacocha, a glacial lake, had increased in size since 1975, and accelerated since 2003. The emissions were a nuisance under the German Civil Code, BGB §1004, and RWE should reimburse a portion of costs incurred to establish flood protection, namely 0.47% of total cost, given RWE's annual contribution to GHG emissions.
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]
In geomorphology, an outburst flood—a type of megaflood—is a high-magnitude, low-frequency catastrophic flood involving the sudden release of a large quantity of water. [1] [2] During the last deglaciation, numerous glacial lake outburst floods were caused by the collapse of either ice sheets or glaciers that formed the dams of proglacial ...
The Seven Rila Lakes in Rila mountain, Bulgaria, are of glacial origin. The Great Lakes as seen from space. The Great Lakes are the largest glacial lakes in the world. The prehistoric glacial Lake Agassiz once held more water than contained by all lakes in the world today. A glacial lake is a body of water with origins from glacier activity ...

In the wake of this and other glacier-related disasters in the Ashish region, notably glacial lake outburst floods that destroyed parts of Huaraz in the preceding two decades, the national government had tried to push forward "hazard zoning" which would limit development in flood and avalanche zones. However, these efforts were largely ...
