Video Captures Terrifying Moment Iceberg Collapsed, Unleashing Huge Tidal Wave Near Boaters

"All I could see was this tidal wave coming toward us."

"I think my heart came up, and I swallowed it. I was petrified," said Wanda Stead to CBC, who captured this dramatic video while boating on Canada's Bay of Exploits with her husband last week. /

The footage shows the iceberg slowly falling apart on the lower-left side, but then suddenly collapse at the arch, sending the majority of the structure collapsing into the water below.

"All I could see was this tidal wave coming toward us," she said to CBC, also admitting they were "too close," parking their boat 100-150 feet away from the large iceberg. /

"Accidents are unplanned events," Snead said to CBC. "You never know with something that big ... and people need to know." Her goal of sharing the video was to make people aware of the dangers of approaching large icebergs like this, according to CBC.

Still shots from other videos uploaded by the boaters show the same iceberg before the collapse, and immediately after when the boaters circled back to check out the result.
