When a GLOF Bursts its Banks

Published on

There is a glacier lake up in Rolwaling Himal above the settlement of Bed ing that is about to rupture. An earthquake or avalanche is likely to break the weak, moraine dam which props up the lake, and releases 71 million cubic metres glacial melt water.

If the water is released slowly, damage will belimited. But chances are that the marine collapse will be sudd en, in which case Nepal will experience a Glacier Lake Outburst Flood, or GLOF, which is greater than all the GLOF phenomena of recent decades.
