List of volcanoes in the United Kingdom
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 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 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.
