Antarctica’s only active volcano shows how CO2 allows volcanoes to form persistent lava lakes on the surface
Left: 3D visualization of the magnetotelluric scan of the interior of Erebus (red is the most conductive and the richest in magma); Right: schematic representation of magmatic processes. Upflow from a deep crustal valve zone experiences episodic breakthrough of CO2 and entrained magma. The spatially continuous upward flow of CO2-dominated magma contrasts with the depth-limited …
