Australian volcano: Watch Big Ben erupt on Heard Island

Video footage has been released of a volcano erupting on Heard Island, an Australian external territory in northern Antarctica. The volcano, named Big Ben, is the highest mountain on the territory and is known to have erupted at least three times since 2000, according to the Institute of Maritime and Antarctic Studies (IMAS). The voyage's chief scientist, IMAS professor and geophysicist Mike Coffin, said the sight of an erupting volcano was an unexpected treat for the crew.
