Topographic map of Ross Island (1:250,000 scale) Mount Erebus is in the lower left. In the center of the summit caldera is a small, steep-sided cone composed primarily of decomposed lava bombs and a large deposit of anorthoclase crystals known as Erebus crystals. Mount Erebus ( /ˈɛrɪbəs/) is an active volcano, the second-highest in Antarctica (after Mount Sidley) and the southernmost active volcano on Earth. Le mont Erebus se trouve dans l’ouest de la dépendance de Ross, la revendication néo-zélandaise sur l’Antarctique gelée par le traité sur l’Antarctique signé le 1er décembre 1959 et entré en vigueur le 23 juin 1961 . Characteristic eruptive activity consists of Strombolian eruptions from the lava lake or from one of several subsidiary vents, all within the volcano's inner crater. Interactive online tool to view volcano webcams and live seismic recordings side-by-side online. Mount Erebus Discovery. Two eruptions were large enough to deposit tephra in the Transantarctic Mountain over 150 km from Erebus. [22], Mount Erebus was discovered on January 27, 1841 (and observed to be in eruption),[23] by polar explorer Sir James Clark Ross on his Antarctic expedition, who named it and its companion, Mount Terror, after his ships, HMS Erebus and HMS Terror (which were later used by Sir John Franklin on his disastrous Arctic expedition). Mount Erebus Volcano - Ross Island, (excert from "Encounters at the End of the World") Mount Erebus is currently the most active volcano in Antarctica and is the current eruptive zone of the Erebus hotspot. Mount Erebus acts like a standard volcano and can erupt. Lava flows of more viscous phonotephrite and trachyte erupted after the basanite. Characteristic eruptive activity consists of Strombolian eruptions from the lava lake or from one of several subsidiary vents, all lying within the volcano's inner crater. "Mount Erebus has been in continuous eruption since 1972, when a small anorthoclase phonolite lava lake was discovered. The oldest eruptive products consist of relatively undifferentiated and nonviscous basanite lavas that form the low broad platform shield of Erebus. Mount Erebus is the most southerly active volcano on the planet. Le mont Erebus est le point culminant de l'île de Ross.Il culmine à 3 794 mètres d'altitude et se présente sous la forme d'une montagne massive [1].La pente générale du relief varie avec l'altitude : elle est assez douce en partie basse et se redresse aux alentours de 30° entre 2 000 mètres à 3 200 mètres d'altitude environ jusqu'au rebord de la caldeira qui couronne le sommet [3]. One of the larger eruptions of Antarctica's Mount Erebus this year occurred at 09:12 UTC on December 4, 2014 and ejected bombs onto the summit cone of Erebus, Mount Erebus Volcano Observatory (MEVO) reports. The upper slopes of Mount Erebus are dominated by steeply dipping (about 30°) tephritic phonolite lava flows with large-scale flow levees. Powered by www.VolcanoDiscovery.com Mont Erebus; Mont Erebus. Erebus is also the southernmost active volcano on Earth and the second-highest volcano in Antarctica. The summit caldera was created by an explosive VEI-6 eruption that occurred 18,000 ± 7,000 years ago. Most eruptions are small and Strombolian in character, tossing bombs onto the crater rim. [26][27] On January 19–20, 1991, Charles J. Blackmer, an iron-worker for many years at McMurdo Station and the South Pole, accomplished a solo ascent in about 17 hours completely unsupported, by snow mobile and on foot.[28][29]. Le mont Erebus a été découvert le 27 janvier 1841 (et observé en éruption) par l'explorateur polaire Sir James Clark Ross lors de son expédition en Antarctique, qui l'a nommé et son compagnon, le mont Terror, d'après ses navires, le HMS Erebus et le HMS Terror ( qui ont ensuite été utilisées par Sir John Franklin lors de sa désastreuse expédition dans l' Arctique). It is 3,794 metres (12,448 ft) high and situated on Ross Island, which also has three inactive volcanoes. Slightly younger basanite and phonotephrite lavas crop out on Fang Ridge—an eroded remnant of an early Erebus volcano—and at other isolated locations on the flanks of Erebus.

Chromolit Wellcome V0025210.jpg 3 129 × 2 250 ; 2,89 Mio Mount Erebus.png 1 524 × 1 174 ; 1,11 Mio A major increase in the size and number of Strombolian eruptions occurred September-December 1984 and buried the lake with ejecta. Mount Erebus (77ø33'S, 167ø10'E, 3794 m above sea level) is the southernmost active volcano in the world. Erebus is the world's only presently erupting phonolite volcano. Mount Erebus in Antarctica erupts. Lava flows of more viscous phonotephrite and trachyte erupted after the basanite. It is the 6t heichest ultra muntain on an island. [32] The mountain directly ahead was lit by sunlight shining from directly behind the aircraft through the cloud deck above, resulting in a lack of shadows that made Mount Erebus effectively invisible against the overcast sky beyond in a classic whiteout (more accurately, "flat-light") phenomenon. The summit contains a persistent convecting phonolitic lava lake, one of five long-lasting lava lakes on Earth. Thus it is the most active volcano in Antarctica. Since Dante had not yet reached the bottom of the crater, no data of volcanic significance was recorded. The highest is Mount Sidley – a … Colors of Iceland: Fire, Earth, Ice and Water, Erebus volcano (Antarctica): elevated activity, explosions, Erebus volcano (Antarctica) activity update: active lava lake in summit crater, Current activity of Bardarbunga volcano, Iceland. culture volcan erebus l ruption du bout du monde. It began to form about 1.3 million years ago and now stands 12,448 feet above sea level. Strombolian and phreatomagmatic eruptions deposited ash‐sized tephra on the flanks of the volcano. The bottom half of the volcano is a shield and the top half is a stratocone. Mount Erebus, Antarctica; the volcano in eruption. Le 28 novembre 1979, quelques heures après son décollage, il s'écrase sur le mont Erebus en ne laissant aucun rescapé parmi les 237 passagers et les 20 membres … 102, 15039-15055. Erebus is one of the largest active volcanoes on Earth. They are dynamic systems that collapse and rebuild, but persist over decades. Mount Erebus is an Antarctic volcano with a height of nearly 4000 metres (12 500 feet). Researchers spent more than three months during the 2007–08 field season installing an atypically dense array of seismometers around Mount Erebus to listen to waves of energy generated by small, controlled blasts from explosives they buried along its flanks and perimeter, and to record scattered seismic signals generated by lava lake eruptions and local ice quakes. Le site du MEVO (Mount Erebus Volcano Observatory) ne peux malheureusement pas maintenir les webcams, qui ne fonctionnent plus depuis le mois de janvier. One of the larger eruptions of Antarctica's Mount Erebus this year occurred at 09:12 UTC on December 4, 2014 and ejected bombs onto the summit cone of Erebus, Mount Erebus Volcano Observatory (MEVO) reports. It is the largest of three major volcanoes forming the crudely triangular Ross Island. Anomalously energetic explosive activity occurred in September 1984, with bombs of up to 10 m in diameter thrown over a kilometer into the air, landing several hundred meters beyond the crater rim. The expedition proved to be highly successful in terms of robotic and computer science, and was possibly the first expedition by a robotic platform to Antarctica.
