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