Continuous lava-lake activity has been documented since 1972, punctuated by occasional Strombolian explosions that eject bombs onto the crater rim. The glacier-covered volcano was erupting when first sighted by Captain James Ross in 1841. An elliptical 500 x 600 m wide, 110-m-deep crater truncates the summit and contains an active lava lake within a 250-m-wide, 100-m-deep inner crater. A summit plateau at about 3,200 m altitude marks the rim of the youngest caldera, within which the modern cone was constructed. The summit of Mount Erebus has been modified by several generations of caldera formation. The 3,794-m-high Erebus is the largest of three major volcanoes forming the crudely triangular Ross Island. Mount Erebus, the world's southernmost historically active volcano, overlooks the McMurdo research station on Ross Island. In addition, infrequent small ash eruptions took place at a vent adjacent to the lava lake. The eruption sizes were based on comparisons of seismic data for known Erebus eruptions.Ģ1 November-27 November 2001 Cite this ReportĪs of 23 November, frequent Strombolian eruptions (~1-10 per day) occurred from a persistent ~15-m-diameter summit lava lake at Erebus.

Number of monthly MODIS-MODVOLC thermal alert pixels recorded at Erebus during 2017-2022. Images use Atmospheric Penetration rendering (bands 12, 11, 8A). The image on 17 February shows a single lava lake, while the image on 4 December shows a larger lake and at least two smaller thermal areas immediately SW.
