Big Ben is a stratovolcano on the uninhabited sub-Antarctic island of Heard , which is part of the Australian outskirts of Heard and McDonald Islands . The highest point ( Mawson Peak , named after the Australian polar explorer Douglas Mawson ) is 2745 meters above sea level. With an area of around 360 km², the mountain covers almost the entire central area of the island.
Big Ben is one of the two active volcanoes in Australia and also the highest mountain on Australian territory. The volcano is completely covered by snow and ice, the crater about 70 meters deep.
Volcanic eruptions took place in the years 1881, 1910, 1950–1952, 1953, 1954, 1985–1987, 1992, 1993, 2000–2001, 2003–2004 and 2006–2008. The most recent phase of the eruption began in 2012 and has continued to the present day.
