Tags: volcanic activity reports, eruptions, Africa, Erta Ale, Ethiopia 1 comment so far The identification of Monday’s eruption in Ethiopia with Erta Ale may have been erroneous. An update on the eruption from Dr Simon Carn of Michigan Technological University via the VOLCANO listserv is circumspect: Satellite instruments detected an eruption in northern Afar, Ethiopia on November 3. The eruption first manifested itself as a large sulfur dioxide (SO2) cloud drifting eastwards over the Arabian peninsula, detected by the Ozone Monitoring Instrument (OMI) and the Atmospheric Infrared Sounder (AIRS). MODIS data from the University of Hawaii’s MODVOLC hot-spot monitoring tool ( [link to modis.higp.hawaii.edu] confirmed an extensive hot-spot (presumably lava flows) near Alu volcano, in the northern part of the Erta ‘Ale range. Details are still sketchy and these observations are as yet unconfirmed from the ground. Ethiopian news sources are also rather round-about in identifying the location of the eruption. The official Ethiopian News Agency describes the eruption as occurring ‘at Ertale volcanic area of Afar State, north-east Ethiopia’, while the EthioBlog also speaks of ‘a volcanic explosion in Ethiopia’s remote north-eastern Afar region’. Wherever the plume came from, it was indeed extensive. The image of the plume below from 5 November, put together from data gathered by the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, is from the NOAA’s currently experimental site displaying near real-time 24hr composite OMI SO2 information (thanks to Nickolay Krotkov for this link). The plume stretches across the Arabian Peninsula, the Gulf, and across Pakistan and northern India. The more red, the higher the concentration of sulphur dioxide. The Activolcans report on the eruption settles for Alu, on the basis of the SO2 monitoring information from OMI and the hotspot report from the University of Hawaii. More on this eruption as news comes in. Erik Klemetti also has detailed coverage at the Eruptions blog. |

Brassia Rex (OP) User ID: 373696 United States 11/06/2008 12:26 PM Report Abusive Post Report Copyright Violation | BBC reports a minor earthquake, and a "record" volume of lava. I wonder what the previous record was, and who keeps track? [link to news.bbc.co.uk] Ethiopia volcano sets lava record A volcanic eruption in 2005 displaced thousands of people Lava flow from a volcanic explosion in Ethiopia's remote north-eastern Afar region has covered a record area, researchers say. Satellite photos show the lava covered about 300 sq km (115 sq miles). According to Addis Ababa University, Monday's eruption prompted a minor earthquake, but there were no reported injuries or damage to infrastructure. When Mount Erta Ale, Ethiopia's only active volcano, erupted in 2005, it displaced thousands of people. It is in the Danakil Depression, one of the lowest and hottest places on earth, which is known for its salt mines. No salt mining today, I guess. |

Quoting: Anonymous Coward 544807Nothing new, though a friend of mine suggested that this was 300 km^2 of ash, not lava. Makes sense. 300 square kms of ash would put it in the low end SUPER ERUPTION category!! So what does that much lava make it? they're already saying it's a new record. An update from Bloomberg of all places: Ethiopia Researchers Observe Nation's Largest Volcanic Eruption By Jason McLure Nov. 6 (Bloomberg) -- The Dalla Filla volcano in a remote area of northeastern Ethiopia erupted this week, spewing lava over tens of square miles in the biggest volcanic eruption in the country's recorded history. Ethiopian researchers working with scientists in the U.K. first detected the eruption on Nov. 3, Ghezahegn Yirgu, a geologist at Addis Ababa University, said by phone today from the capital. Officials have been sent to the Afar region to investigate the explosion, which was of a similar magnitude to eruptions of Mount Etna in Italy in May, he said. ``We have never heard of anyone observing anything like this here,'' Yirgu said. ``People heard loud noises and explosions from a distance and saw smoke and felt the ground shake.'' Dalla Filla is about 600 kilometers (373 miles) northeast of Addis Ababa and 20 kilometers north of the Erta Ale lava lake. It's the third eruption in Ethiopia's Afar region since 2005, Yirgu said. Located in an arid section of northeastern Ethiopia and bordering both Eritrea and Djibouti, many of the Afar region's inhabitants are semi-nomadic herders. A number of the world's best-known fossils have been discovered in Afar, including one of the earliest ancestors of man, known as Lucy. [link to www.bloomberg.com] |
