Subject: [Rockhounds] Extremely Rare Lava Lake Discovered on Remote British Island

Satellite images have confirmed the presence of a persistent lava lake within the crater of Mount Michael—an active volcano located on a remote island in the Southern Ocean.

potentially
active terrestrial volcanoes on Earth, only eight feature a persistent lake of lava, the new one included. A research team from the British Antarctic survey and University College London confirmed the presence of lava lake using satellite data collected over the past three decades. Details of the discovery were published <https://doi.org/10.1016/j.jvolgeores.2019.05.002> in the latest edition of the Journal of Volcanology and Geothermal Research.
