VIDEO: Break-off Sulzberger Ice Shelf in Antarcica Due to Japan Tsunami in March 2011

Anyone one in the world could hardly imagine that recent tsunami in Japan would have any tearing effects in the continent of Antarctica; but it’s really true.

Before (left) and after (right) photos of the Sulzberger Ice Shelf illustrate the calving event associated with the Japan earthquake and resulting tsunami that occurred on March 11, 2011. The icebergs have just begun to separate in the left image.

Waves generated by the massive March 2011 undersea earthquake off Japan travelled 8000 mi. to chop 50 sq. mi. of ice off the Sulzberger Ice Shelf. NASA and ESA satellites captured imagery of the break. Ice may have been weakened by climate change.

According to NASA; the break-off of icebergs apparently occurred about 18 hours after the tsunami struck the Japanese coast and Kelly Brunt, a cryosphere specialist at the Goddard Space Flight Center in Greenbelt, Maryland, and her colleagues, were able to relate the two occurrences directly.
