However the berg has not yet floated away from its position, which could be because it's grounded on underwater hills or because of sea currents and winds...
"The calving occurred sometime between Monday 10 July and Wednesday 12 July 2017, when a 5,800-square-kilometre section of Larsen C finally broke away. The iceberg, which is likely to be named A68, weighs more than a trillion tonnes. Its volume is twice that of Lake Erie, one of the Great Lakes."
"There is a risk that Larsen C may eventually follow the example of its neighbor, Larsen B, which disintegrated in 2002 following a similar rift-induced calving event in 1995."
The iceberg could remain where it is – some have been known to stay in position for as long as 20 years – float away into the ocean currents in a massive single block or break up into smaller bergs.
