The Journal of Glaciology, and NASA, says that 18 hours after the massive March 11 tsuanami hit Japan, it torn off huge chucks of ice at the South Pole.

Large pieces of the Sulzberger ice shelf, one the size of Manhattan, broke off between March 12 and 16.  NASA scientists watched and took pictures of the event using a satellite.

NASA said they immediately turned there eyes towards the South Pole when the March 11 tsunami hit Japan.  They wanted to test a long time hypothesis, that large numbers of ice bergs appearing in the ocean coincide with large earthquakes and tsunamis.  They got their proof.

Amazingly the tsunami was only one foot high when it hit the Sulzberger ice shelf.
