There are no active volcanoes in the United Kingdom of Great Britain and Northern Ireland, but there are a few active volcanoes in some British Overseas Territories. Queen Mary's Peak in Tristan da Cunha erupted in 1961-2. The Soufrière Hills volcano on the Caribbean island of Montserrat erupted three times between 1995 and 2013. Mount Belinda in the British Overseas Territory of South Georgia and the South Sandwich Islands, erupted between 2001 and 2007. Mount Michael, also in South Georgia and the South Sandwich Islands, 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.
