The summit of Antarctica's Mount Erebus is the world's southernmost active volcano. It contains an elliptical 500 x 600 m wide crater whose NE side contains a 250-m-wide, 100-m-deep inner crater. The flat, snow-covered floor of the Main Crater is about 100 m below its rim. A plume rises from the inner crater that has contained an active lava lake since 1972.
