Surging or Surge-type glaciers

These are short-lived events where a glacier can advance and move at velocities up to 100 times faster than normal.
They cluster around a few areas.
High concentrations of surging glaciers occur in Svalbard, the Canadian Arctic islands, Alaska and Iceland.
They also represent 40% of the total glaciated area of the Karakoram range.
