You're watching the biggest chunk of an iceberg breaking off a
glacier ever captured on video. It is incredible.  That's a 1.75
cubic mile chunk of ice. The most basic way to put that into
perspective is to imagine if out of nowhere, a huge portion of
the island of Manhattan just snapped off into the ocean. And,
like the filmmakers who were lucky enough to capture this
amazing spectacle, you happened to catch the event on your
camera. All you can say is whoa. [The Guardian]
