Mount Erebus, the world's southernmost historically active volcano, is viewed here from the SW, near the McMurdo research station on Ross Island. The 3794-m-high Erebus is capped by an elliptical 500 x 600 m wide, 110-m-deep summit crater that contains an active lava lake. The glacier-covered volcano was erupting when first sighted by Captain James Ross in 1841. Continuous lava-lake activity has been documented since 1972, punctuated by occasional strombolian explosions that eject bombs onto the crater rim.
