Plus d'un mois après janvier the17 attaque sur les touristes et les scientifiques au volcan Erta Ale, dont 5 ont été tués, plusieurs blessés et 4 les personnes enlevées, il est encore sans nouvelles fiables quant au sort de l'enlèvement. ...plus
Le rebelle Afar révolutionnaire démocratique l'unité Front (ARDUF) a revendiqué l'attaque et a ajouté que les touristes allemands 2 kidnappés et deux guides éthiopiens sont en bonne santé et seront publiés s'il y a une issue diplomatique « positive » avec l'Éthiopie qui accuse l'Erythrée à l'appui de ARDUF, Reuters rapporte. En attendant, groupes reviennent à la zone de nouveau. Le gouvernement éthiopien a dit avoir établi une unité militaire de semi permanente d'accroître la sécurité pour les touristes au volcan.

Volcan ERT Ale, le site de l'attaque meurtrière terroriste 4 semaines, dans lequel 5 personnes ont été tuées, plusieurs blessés et 4 enlevé, est maintenant ouvert pour les groupes de tour encore une fois, les sources locales confirment nous et les premières voyagistes européens ont repris leurs expéditions (ou jamais annulé leur, malgré les accidents...). ...plus
Selon notre correspondant à Addis-Abeba, le gouvernement éthiopien est de mobiliser des troupes mécanisées et clôturé la proche frontière avec l'Érythrée (où les assaillants présumément vient) et établir une force permanente sécurité spéciales dans les domaines du Dallol et Ert Ale. Ceci illustre la situation particulière dans cette région, mais selon les voyagistes en Éthiopie, la région peut maintenant être considéré comme "100 %" sécuritaire. Malheureusement, il n'y a qu'aucune bonne nouvelle encore sur le sort des 4 n'enlevé des touristes allemands et guides éthiopiens, sauf que les négociations entre les diverses parties impliquées (gouvernements de l'Allemagne, l'Éthiopie, l'Érythrée et les chefs locaux de Afar) sont « en cours ». Nous espérons pour leur libération bientôt ! [moins]
Nous avons des détails maintenant plus précis de ce qui est arrivé à Erta Ale hier et peut confirmer que l'attaque n'était pas le Dallol comme nous soupçonnions, mais sur le cratère du volcan Erta Ale. ...plus
Pour les années maintenant, cela a été un endroit de camping populaire pour les touristes qui visitent le lac de lave spectaculaire. Selon nos correspondants à Addis, qui sont en contact par téléphone satellite avec des guides sur l'emplacement de la région, l'attaque est arrivé mardi autour de 01:00 heure locale. 5 personnes au moins ont été abattus par un groupe de rebelles armés de l'Érythrée, qui soudainement ouvert le feu sur le groupe. Touristes en provenance de l'Allemagne et la Hongrie (la fatalité Austrial ne fut pas confirmée dans notre rapport) parmi les victimes. Leurs corps sont arrivés dans la ville de Semera, la capitale de la région Afar. [moins]
Significant changes have occured recently at Erta Ale volcano, the lava lake having filled up the south crater and overflowed repeatedly into the N and NW section of the caldera floor adjacient to the crater. ...plus
During our latest expedition, we stayed on Erta Ale from early 25 Nov - 28 Nov. Upon our arrival, those changes very obvious. The lava lake had risen to the level of the former lower N section, the old terrace was gone, and the whole south crater was filled by overflows to the level of the lower old N-NW rim. Flows had indeed overflowed that section of the old crater circumference on a length of about 150m, or about 1 third of the old circumference. The still hot overflows had covered the outside caldera floor to about 50-100 distance, and one long flow, probably dated from 24 Nov (judging from its temperature) had almost reached the W caldera walls, as it followed the descending floor of the caldera in that direction. The still active lake itself was circular, about 40 m in diameter (about 2 thirds to half its size observed in 2008 and 2009), contained within a low ring-shaped wall and extremely active. Degassing fountains kept the whole surface violently boiling most of the time. [moins]
Scientists have observed that the lava lake at Erta Ale had some Strombolian activity in the southern pit crater during 20-23 November 2010. They have seen that the lava lake had filled the the pit crater and that lava flew also into the main crater.There was a little 4 m high scoria ring at the vent. ...plus

As visitors report, the lava level of Erta Ale has risen to within 10 meters beneath the rim of the south crater and is flooding its terrace frequently.
The new fissure eruption in the Danakil near Erta Ale earlier this month, on 14-15 August, is reported to have killed five people, hundreds of camels and and drove more than 2 000 people from their homes. According to Ethiopian news sources, the "eruption also opened a 10km crack in the ground and spewed lava 300m in the air." ...plus
It is likely this is in fact not an eruption related to Erta Ale volcano. A more likely candidate could benearby Dabbahu volcano, a new fissure which had its first historic eruption in late Sept (26) - early Oct 2005. It could also be even a new volcano born from a new fissure: a new episode in the dramatic chapter of Earth's History called the "Splitting apart of East Africa". The occurrence of fissures and fissure eruptions in the area is not surprising, given the very geologic nature of the Afar triangle. Here, the two segments of the African plate and the adjacient Arabian plate are being pulled apart from each other, as East AFrica is slowly moving away from the rest of the continent. At the same time, the Red sea and the Gulf of Aden are widening and those movements are combined in the triple junction, which is the Afar triangle. Here, the crust is continuing to thin and the ground is sinking, until until one day, in geologically near future, the land will be flooded by the Red Sea to mark the initial stage of a new ocean.

A team of scientists visited the Da'Ure locality immediately adjacent to the NE flank of the Quaternary Dabbahu (or Boina) felsic complex on 4 and 5 October after receiving reports of volcanic activity there on 26 September. People in the area noted that on 26 September at about 1300 a very strong earthquake shook the area, and was followed by a dark column of "smoke" that rose high into the atmosphere and spread out to form a cloud, which darkened the area for 3 days and 3 nights. The scientists determined that a minor explosive eruption occurred from two semi-circular vents, producing ashfall that was ~5 cm thick near the vent. Ash deposits extended more than 500 m from the vent. Boulders emitted during the eruption were as large as 3 m and were deposited as far as 20 meters away. The scientists noted intense degassing from the vents, the scent of sulfur dioxide, and the sound of boiling water in the vents. As of about 10 October, the Addis Ababa University Geophysical Observatory reported that seismic activity in the area was continuing.
Background: Dabbahu, also known as Boina or Moina, is a Holocene volcanic massif forming an axial range of the Afar depression SSW of the Alayta massif. Pantelleritic obsidian flows, lava domes, and pumice cones form the summit and upper flanks of the volcano, which rises above the Teru Plain and was built over a base of basaltic-to-trachytic lava flows of a shield volcano. Late-stage basaltic fissure eruptions occurred at the NW base of the volcano. Abundant fumaroles are located along the crest of the volcano and extend NE towards Alayta.
One week after the start of the eruption of Erta Ale, some details emerge as news reports come in: the crater of the large shield volcano has rapidly filled with fresh lava and possibly overflowed, destroying farmland and killing much livestock. strong strombolian or hawaiian activity is producing thick clouds of ash that shower over the volcano's surroundings.
A group of scientists assessed the visible changes at Erta Ale on 26 September after activity began around 24 September. In comparison to observations made in November 2004, they found that the southern main crater/pit had widened significantly, with portions of the previous crater walls having collapsed into the lava lake. A new cone-shaped construct had grown within the southern main crater where there had been a platform. A lava lake occupied the entire width of the inner crater/pit. In the northern crater/pit, there was a solidified lava bulge and abundant "smoking" along the crater walls. No incandescent lava was visible in the pit. Based on descriptions by local residents of seeing "red and glowing light shooting and rising into the air above the volcano," the scientists believe that a Strombolian eruption probably occurred, emitting a significant volume of fresh magma within, and possibly out of, the pit.
No fatalities have been reported, but the Ethiopian government evacuated about 50,000 nomads in the surroundings of the volcano. A committee has been set up at to study the magnitude of the damage.
Erta Ale volcano in northern Afar, Ethiopia, well-known for its long-lived active lava lake that had occupied its crater up until 2004, erupted yesterday according to unconfirmed reports from local authorities. The eruption followed a series of earthquakes of up to 5.5. magnitude Richter scale that occurred in the area the day before.
