A chain of a dozen undersea volcanoes some reaching nearly 10,000 feet above the ocean floor , and several of them active, have been near Antarctica, south of the South Sandwich Islands — desolate, ice-covered volcanoes that rise above the southern Atlantic Ocean about halfway between South America and South Africa which erupted as recently as 2008. It was the first such discovery in that region.
"That's a big volcano. That's a very big volcano. If that was on land it would be quite remarkable," said Philip Leat, a volcanologist with the British Antarctic Survey who led a seafloor mapping expedition to the region in 2007 and 2010. "We knew there were other volcanoes in the area, but we didn't go trying to find volcanoes,"
"It was quite frightening, actually," Leat said. The onboard instruments revealed that some of the peaks rise within 160 feet of the ocean's surface.
The team mapped an area about 100 miles wide and nearly the length of Britain. The missing parts of the image are where islands blocked the mapping sonar.

I have a gut feeling there is going to be a massive EQK in the Antartica between 2011-2014.
