The tsunami caused by the 11 March Tohoku earthquake in Japan crossed the Pacific and broke off large chunks of ice from Antarctica, a study has shown.

Satellite photos show huge icebergs were created when the tsunami hit West Antarctica's Sulzberger Ice Shelf.

This caused 125 sq km of ice to break off - or calve - from a shelf front that has remained stable for the past 46 years.

The work, by a US team, is published in the Journal of Glaciology.

The waves generated by the 9.0 Magnitude earthquake in Japan travelled about 13,000km across the Pacific Ocean before reaching the Sulzenberger Ice Shelf, causing ice to break off and float into the sea.

This should throw predictive models of Antarctic melting a real twist ...

1. again, proof that this earth is a whole system

can't do something in one place and expect it to not effect the rest of the whole...

wow, didn't this earthquake shift the earth rotation as well?

2. 'mean North pole" was shifted by about 2.5 centimeters (1 inch) in the direction of 145º East Longit
