Watch a huge iceberg suddenly collapsing

A couple was on vacation, and the two were filming a big, spectacular iceberg. However, their video took an unexpected turn when the iceberg started to collapse, sending a big tidal wave towards their boat.

Warning: there are some ear piercing screams in this video

The video was filmed in the Bay of Exploits, Newfoundland, Canada.

“I think my heart came up, and I swallowed it. I was petrified,” Wanda Stead tells CBC. “All I could see was this tidal wave coming toward us.”
