Dienstag, Mär 06, 2012
Die beiden vor 6 Wochen am 17. Januar am Erta Ale Vulkan in Äthiopien's Danakilwüste entführten deutschen Touristen sind offenbar freigelassen worden, berichten Nachrichtenagenturen aus Addis Ababa. ...mehrLaut AFP hat die Vereinigte Revolutionär-Demokratische Front von Afar (ARDUF) erklärt, die beiden deutschen Touristen bereits am Montag an Stammesvertreter der Afar und von dort weiter an Mitarbeiter der deutschen Botschaft übergeben zu haben. Das Auswärtige Amt hat diese Angaben aber noch nicht offiziell bestätigt. Die beiden Touristen waren bei einem bewaffneten Überfall am Camp des Erta Ale Vulkans zusammen mit 2 äthiopischen Guides in die Nähe der eritreischen Grenze entführt worden. Bei dem blutigen Überfall wurden 5 weitere Touristen aus Ungarn, Österreich und Deutschland brutal ermordet. [ less] [ alles lesen]

Ert Ale Vulkan, den tödlichen Terroranschlag 4 Wochen, in denen 5 Menschen getötet, mehrere verwundet und 4 entführt, ist jetzt offen für Reisegruppen wieder und lokale Quellen bestätigen uns die erste europäische Reiseveranstalter haben ihre Expeditionen wieder aufgenommen (oder nie storniert sie, trotz der Unfälle...). ...mehrLaut unser Korrespondent in Addis Abeba die äthiopische Regierung ist Mobilisierung mechanisierte Truppen und eingezäunt die nahe Grenze zu Eritrea (wo die Angreifer vermutlich herkommt) und schaffen eine dauerhafte spezielle Sicherheit Kraft in den Bereichen Dallol und Ert Ale. Dies zeigt die besondere Situation in dieser Region, aber laut Reiseveranstalter in Äthiopien, Bereich kann nun als "100 %" sichere. Leider gibt es keine guten Nachrichten noch über das Schicksal der 4 deutsche Touristen entführt und äthiopischen Führer, außer, dass Verhandlungen zwischen den verschiedenen Parteien Beteiligten (Regierungen von Deutschland, Äthiopien, Eritrea und die lokalen Afar Chiefs) "laufen". Wir hoffen auf ihre Befreiung bald! [ less] [ alles lesen]

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. ...mehrDuring 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. [ less] [ alles lesen]

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. ...mehr [ alles lesen]

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." ...mehrIt 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.

Volcanic activity at Erta Ale reported previously actually occurred at Dabbahu: ...mehrA 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. [ less] [ alles lesen]

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. ...mehrA 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.
