A huge iceberg, roughly twice the size of New York City, is set to soon break off from the Brunt Ice Shelf in Antarctica. With two large cracks due to meet within the next few months, a research station has already been relocated as scientists watch the rifting event enter its "final phase."

The soon-to-be-born iceberg would measure more than 1,500 sq km (580 sq mi), and is between 150 and 250 m (492 and 820 ft) thick.

Chasm 1, as it's known, has grown steadily over the last seven years.
