Damn Nature U Scary

Courtesy of Sploid: "Norefjell [a mountain range in Norway] 2014-01-05. A quiet skiing, suddenly something happens 50 feet from the trail. Power line at 132 kV corresponding EB-line. The estimate lasted at least five minute." I prefer mine.

"Rare!!! Slow and very powerful avalanche. We hear the sound of trees that break!!!" reads video's caption.
