A video posted on Youtube Tuesday shows a huge, chunk of ice, covered with volcanic ash, breaking off Svínafellsjökull glacier, which is part of Vatnajökull glacier. It then rolls on the side, like a blue whale, and floats majestically into a lagoon. Behind it, the tranquility of a whale-shaped, blue iceberg is disturbed and it, too, rolls on the side, as is if in a synchronized dance.
The first part of the video turns sideways, but the rest turns right.
Svínafellsjökull has been a popular site for filming, RÚV reports. It was prominent in the film Interstellar, directed by Christopher Nolan, and in the series Game of Thrones.
