As of Jan. 16, the megaberg, known as A23a, is roughly 180 miles (290 kilometers) away from South Georgia and the South Sandwich Islands, according to location coordinates from the U.S. National Ice Center. A collision with these islands could be catastrophic for the large colonies of penguins, seals, and other wildlife that live there.

The world’s largest iceberg is still on the move and there are fears that it could be headed north from Antarctica towards the island of South Georgia.

Millions of seals and penguins are threatened by a very large iceberg drifting toward their remote island in the South Atlantic. The giant iceberg, named A23a, is the world's largest iceberg ever to break loose from Antarctica.
