Main article: Lists of volcanoes

There are no active volcanoes in Great Britain or Ireland, but there are a few in British dependent territories. One of the largest is Mount Belinda 1,370 m (4,490 ft) at 58°25′S 26°23′W on Montagu Island in the Weddell Sea off the coast of Antarctica. It is within the British Overseas Territory, the South Georgia and the South Sandwich Islands. Although, Mount Michael 805 m (2,641 ft) at 57°48′S 26°28′W on Saunders Island has been active as recently as 2005. The 700 m (2,297 ft) diameter summit crater is thought to possibly contain an active lava lake, one of only a handful in the world.
