A massive iceberg over 100 times heavier than the one which sunk the Titanic has broken off in Antarctica.
The monolithic ice fissure had previously been developing along the Larsen C Ice Shelf, which was being tracked by Nasa, but has now broken away.
The iceberg is reportedly four times the size of London and, as 6,000 sq km, is one of the biggest ever recorded.
It also weighs 1 trillion tonnes - 130 times the size of the iceberg which sunk the Titanic in 1912.
However today's ship captains have no cause to worry as yet, for the position of the mass has prevented it from floating away into open water - with underwater hills believed to be anchoring it in place.
