Look, A GLOF!

Glacier Lake Outburst Floods might be the the next big topic due to the climate changing.  Also called a "Tsunami from the sky" it´s basically killer waves of water, stones and other rubble rolling down mountains sides due to glacier lakes rising in level, especially in the Himalaya region.  So if the water on the shorelines is rising, Tsunamis heading towards us from the mountains, middle height plains could gain some neo popularity... Or is there a new fun sport due in Nepal, called Rubble Rock Surfing?
