The size of this iceberg is larger than New York city. It broke off from the Brunt ice shelf near Britain’s Helley research station which was luckily empty at that time. The reason for this as cited by BAS is the process of calving.
In the process of Ice calving or iceberg calving ice blocks break away from an ice shelf or the edge of a glacier. In simple language it is a sudden breaking away and release of a mass of ice.
Currently BAS is monitoring the impact of calving which is not easy to predict. Experts believe that calving of this magnitude may lead to breaking more ice bergs off the ice shelf.
