A Jökulhlaup, also known as a GLOF or Glacial Lake Outburst Flood, happens when water trapped by glacier ice suddenly finds a way out. The pressure can lift and fracture the ice, allowing the lake to drain rapidly beneath the glacier and rush downhill with incredible force.
This is a fairly common occurrence but rare to capture as they happen in very remote areas. This one on Columbia Glacier in Alaska has been occurring annually since 2014.
