  • , small total volume and short duration. The floods happen mostly from late summer to early autumn. Frequent glacier outburst floods indicate glacier advance and climatic variations.

  • On September 16th, 1986, an ice avalanche from a hanging glacier near the K2 peak at 7 800 m, Karakorum, triggered a massive avalanche of ice and snow. Ice and snow, impacting on the path, formed a dust cloud at the advancing tip. On the basis
