A steam plume rises above an active lava lake in the summit crater of Erebus volcano in December 1983. The currently active lava lake at Erebus was first observed on December 24, 1972. Lava-lake activity accompanied by intermittent strombolian eruptions has been observed during annual scientific expeditions since then. The active lava lake is located at the bottom of an inner 100-m-deep crater, whose flat, snow-covered rim forms a bench at the right (SW) side of the Main Crater.
