By Caroline Taylor What is a glacial lake outburst flood? Glacial Lake Outburst Floods (GLOFs) refer to the sudden release of meltwater and sediment from a dammed lake1. Across the globe there are many types of glacial lake dams, including moraine-dams, ice-dams, bedrock-dams, and landslide-dams 2, all of which can produce GLOFs. Why are […]

There are many ArcGIS Story Maps around. Some are better than others; some take too long to load or are not well thought through. But some are excellent. Asia’s melting glaciers This well made Storymap focuses on melting glaciers in High Mountain Asia, and the impact this will have on water resources. Who owns Antarctica?

A glacial lake outburst flood (GLOF) is a release of meltwater from a moraine- or ice-dam glacial lake due to dam failure1,2. GLOFs often result in catastrophic flooding downstream, with major geomorphic and socioeconomic impacts3,4. GLOFs have three main features: They involve sudden (and sometimes cyclic) releases of water. They tend to be rapid events,
