A mighty crack...

This is quite something -- a vast crack that opened up on the floating section of the Pine Island Glacier, Antarctica.  Somewhat larger than your average crevasse, this was the precursor to a major calving event........

The crack was at least 25 km long, and was first observed in 2011.  The calving event finally took place between Oct 28th and Nov 13th 2013, when Iceberg B-31 was born.  It is 35 km x 20 km in extent -- ie roughly the size of Singapore. 

This is a satellite image of the same crack:
