Mount Michael is an active volcano with a height of 843m. It is located on Saunders Island in the South Sandwich Islands, a British Overseas Territory in the southern Atlantic Ocean. It is one of the few volcanoes in an overseas territory of the United Kingdom. The volcano was discovered by a British expedition under James Cook in 1775, but was presumably first charted in 1820 by a Russian expedition under Fabian Gottlieb von Bellingshausen. It was recharted in 1930 by DI personnel under Commander W.M. Carey of the Royal Navy, who was captain of the Discovery II at the time of the survey.
Persistent lava lake
[edit]In 2019, it was discovered that Mount Michael had a persistent lava lake, a rare phenomenon which is known to occur at only eight volcanoes in the world.[1][2] In November 2022, an expedition from University College London led by geologist Emma Nicholson reached the summit of the volcano and was able to confirm the existence of the lava lake.[3]

The area is often cloudy, and a seemingly constant volcanic plume conceals the lake most of the time. Fortunately, the team collected enough shots of the lake from 2003 to 2018 that clearly showed a crater floor containing a superheated lake 295 to 705 feet across. The lava is also 1,812 to 2,334 degrees Fahrenheit, with the higher end of that range about as hot as lava on Earth seems to get.
