Tourists at a lagoon in Iceland make a run for it when part of the glacier collapses

Tourists in Iceland were frolicking near a lagoon that is accessible only with a guide, when part of a glacier broke off, causing them to make a run for it. According to YouTube, the person filming said, "This area is only accessible with mountain guides and everybody shown in the video had been previously instructed to immediately leave the beach if a calving occurs...Due to the sheer size and proximity it was a bit of a close call but everybody was safe and stayed dry.”

It doesn't look like a "close call" when watching it on video, but the rolling waves it caused are amazing.
