Japan Tsunami Caused Icebergs To Break Off

Japan Tsunami Caused Icebergs To Break OffJapan Tsunami Caused Icebergs To Break Off, The tsunami that struck Japan on March 11 waves propagate that hit a patch of ice in Antarctica 13,000 kilometers (8,100 miles) away, shattering part of her huge icebergs, the European Space Agency (ESA) said on Tuesday.

On 12 March, ESA’s Envisat Earth’s satellite monitoring icebergs that had been separated from the Sulzberger Ice Shelf, and March 16, the pieces were seen floating in the Ross Sea, he said.

The largest iceberg is about 9.5 kilometers (5.9 miles) by 6.5 kilometers (four miles), making it slightly larger in area of?? Manhattan, and probably had a depth of 80 meters (260 feet).

The tsunami was at least 23 meters (76 feet) having been generated by an undersea earthquake of magnitude 9.0, according to estimates in Japan published a week after the event.

Analysis of radar images from Envisat experts from the U.S. suggests that the waves were probably only about 30 centimeters (18 inches) high at the time they crossed 13,000 km (8,100 miles) of ocean.

Still, the pace up and down movement was enough to highlight the rigid structure of the ice shelf, causing pieces to break at its edge, the ESA said in a news release.

Research linking the iceberg calving tsunami was conducted by a team led by Kelly Brunt, an ice specialist at NASA Goddard Space Flight Center in Maryland. Their study appears in an online publication, the Journal of Glaciology.

Ice shelves are thick ice floating beds that attach to the coast. The glaciers of ice create them whose discharge into the sea.
