Continuous lava-lake activity with minor explosions, punctuated by occasional larger strombolian explosions that eject bombs onto the crater rim, has been documented since 1972, but has probably been occurring for much of the volcano's recent history. 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. The 3794-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. of Hawai'i, 2525 Correa Road, Honolulu, HI 96822, USA (URL: ) Sentinel Hub Playground (URL: ).Mt. Information Contacts: Hawai'i Institute of Geophysics and Planetology (HIGP) - MODVOLC Thermal Alerts System, School of Ocean and Earth Science and Technology (SOEST), Univ. Continuous lava-lake activity with minor explosions, punctuated by occasional larger Strombolian explosions that eject bombs onto the crater rim, has been documented since 1972, but has probably been occurring for much of the volcano's recent history. And reaching out to Antarctica, about 4,500km (2,780 miles). The glacier-covered volcano was erupting when first sighted by Captain James Ross in 1841. The Mount Erebus tourist plane disaster killed 257 people and would have a lasting legacy. 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 other lava lakes are sometimes present. A summit plateau at about 3,200 m elevation marks the rim of the youngest caldera, which formed during the late-Pleistocene and within which the modern cone was constructed. The summit of the dominantly phonolitic volcano has been modified by one or two generations of caldera formation. ![]() It is the largest of three major volcanoes forming the crudely triangular Ross Island. Two quiescent potentially explosive volcanoes in Northern Victoria Land are. The table was compiled using data provided by the HIGP - MODVOLC Thermal Alerts System. Melbourne), as well as small active edifices (Mt. See BGVN 42:06 for data from 2000 through 2016. Number of monthly MODIS-MODVOLC thermal alert pixels recorded at Erebus during 2017-2021. The scene: a tent on Mount Erebus, an active volcano on Ross Island, Antarctica. Images use False Color rendering (bands 12, 11, 4). 20 min read This story appears in the July 2012 issue of National Geographic magazine. The image on 23 January 2021 (left) shows a single lava lake, while the image on 30 October 2021 (right) shows a larger lake at least one smaller thermal area immediately SW. Sentinel-2 infrared satellite images showing the active lava lake in the summit crater of Erebus during 2021. Based on MODIS infrared detectors aboard the Terra and Aqua satellites and analyzed using the MODVOLC algorithm, thermal activity during 2021 was much greater than the 2020 level (76) but much less than the 20 levels (774 and 624, respectively) (table 7).įigure 30. Occasionally, a white gas plume was visible. Sentinel-2 satellite images during 2021 showed a single lava lake, except a much smaller second one on 30 October (figure 30). This report documents activity during 2021. ![]() Erebus Volcano Observatory suspended their seismic and infrasonic monitoring program in 2016, the volcano has been primarily monitored by satellite. Since 1972, and probably well before, minor explosions, punctuated by occasional larger Strombolian explosions, have been associated with the active lava lake. 3794 m All times are local (unless otherwise noted)Įrebus, located on Ross Island, Antarctica, is one of the few volcanoes in the world with a persistent lava lake in its summit crater. Erebus (Antarctica) Increased thermal activity during 2021 compared to 2020. 2 (February 2022) Managing Editor: Edward Venzke. Bulletin of the Global Volcanism Network, vol. Antarctica, Mount Erebus plume behind McMurdo. (Bureau of Aircraft Accidents Archives) In 1841, Sir James Clark Ross and his crew sailed into a nameless bay on the hitherto unknown continent of Antarctica, and there watched awestruck as a towering volcano spewed fire into the midnight sun.
