Glacial Lake Outburst Flood

A glacial lake outburst flood, or GLOF, is sudden release of water from a lake fed by glacier melt that has formed at the side, in front, within, beneath or on the surface of a glacier. It can be impounded by moraine complexes, glacial ice or even bedrock and, as a result of breaching, slope failure, overtopping or other failure mechanisms, can lead to catastrophic phenomena in the high mountains that threaten people’s lives, livelihoods and regional infrastructure.
