In a video uploaded by a tourist from Australia they get more than they bargained for when they got a ride to the glacier just north of Ilulissat, Greenland.
The video starts out with the tourist filming the glacier noticing that something is about to happen with glacier. Then all of a sudden a large chunk of the berg falls into the water, sending a large wall of water towards the boat.
Iceberg Tsunami from a different angle.
