This has got to be one terrifying moment, as a boat with a tourist and crew were observing a gigantic glacier in Greenland a huge chunk of it breaks off into the ocean causing an instant Tsunami, nearly capsizing the boat and causing serious problems for the people on board.

YouTube user ' describes the incident like this:

"A tourist from Australia came to my uncle and asked if she could get a ride to the glacier just north of Ilulissat, Greenland, so he asked me if I wanted to be his translator. I am from another town where glaciers are fairytales, I was as much of a tourist as the Australian tourist, so I decided to join the crew. The beautiful scenery was amazing, but the nature doesn't care about anyone. That day almost became our last day."
