Japanese tsunami and the birth of icebergs

Scientists have long speculated that large tsunamis could be linked to the calving of icebergs—where chunks of ice break off of the side of a glacier or ice shelf and float away.

Fascinating stuff, and a great reminder of how interconnected the world really is.
