List of volcanoes in the United Kingdom

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 1,370-metre (4,490 ft) Mount Belinda at 58°26′06″S 26°22′53″W on Montagu Island in the Weddell Sea off the coast of Antarctica. It is within the British Overseas Territory of the South Georgia and the South Sandwich Islands.

Mount Michael (805 m (2,641 ft)), at 57°48′03″S 26°29′18″W on Saunders Island, was active in 2005. Its 700-metre-diameter (2,300 ft) summit crater is thought to possibly contain an active lava lake, one of only a handful in the world.
