The crack known as Chasm-1 had until 2012 been dormant for about 35 years, but over the last decade developed naturally as the ice shelf flowed towards the sea at a rate of about 2km per year.
It is not believed to be due to climate change, as atmospheric temperatures above the Brunt Ice Shelf are consistently sub-zero, and no warmer ocean water penetrates into the cavity under the shelf. The iceberg calved when Chasm-1 extended completely through the 150-metre thick ice shelf.

That would be a pretty significant sized Iceberg. I wonder how big the biggest Iceberg was?

If you look at the picture insert in the article, it mentions them at the bottom (B-15 was the largest officially, but unofficially the one from 1956 is)
