Mount Erebus is the southernmost active volcano on Earth and is located on Ross Island in Antarctica. It has an elevation of 3794 meters and is surrounded by three inactive volcanoes, Mount Terror, Mount Bird and Mount Terra Nova. Volcanism on Ross Island is related to the presence of the Erebus hotspot in the deep subsurface and as a result, continuous eruptions occur from the persistent lava lake in the inner crater of Mount Erebus. The volcano is also known for its ice fumaroles, towers of ice that form around gases escaping from vents in its surface.
