An earthquake swarm began under Eyjafjallajokull volcano in January 2010. A second jokulhlaup/lahar emanates from the ice cap down the Markarfljot valley in the evening. Very little steam was observed at Gígjökull glacier on the northern side of the volcano. (pdf from ppt presentation), Eruption update: 17 April, morning – stable eruption, change in wind conditions. see memo by Thorvaldur Thordarson, Guðrún Larsen and Ármann Höskuldsson, Hazard due to eruptions and floods from Katla and Eyjafjallajökull, south Iceland, Eyjafjallajökull eruption: 20 March to present, Map of the lava flow on Fimmvörðuháls from 21 March - 7 April 2010, Eyjafjallajokull Volcano - GPS Time Series, New map of the lava flow from 21 - 24 March 2010, Results from observations flights over the eruption site 21 and 22 March 2010, http://www.volcano.si.edu/world/volcano.cfm?vnum=1702-02=, http://www.vedur.is/media/vedurstofan/utgafa/skyrslur/2009/VI_2009_013.pdf, http://www.raunvis.hi.is/~mtg/nemritg/BV-MS_2009.pdf, InSAR based sill model links spatially offset areas of deformation and seismicity for the 1994 unrest episode at Eyjafjallajökull volcano, Iceland. Locals reported lava fountaining and a lava flow from the glacier. Acquired May 2, 2010, this natural-color image shows an ash plume and steam over the summit of Eyjafjallajökull Volcano. Additional localised disruption continued into May 2010. Visual observations yesterday: Regular explosions at intervals of few minutes were observed in afternoon, with fluctuations in intensity and tephra content. Katla did not display any unusual activity (such as expansion of the crust or seismic activity) during the 2010 eruptions of Eyjafjallajökull, though geologists have been concerned about the general instability of Katla since 1999. 17th April Update On 15 April the eruption plume reaches mainland Europe with closure of airspace over large part of Northern Europe. Since the onset of the explosive eruption the tremor has overall been gradually increasing, with superimposed fluctuations. The eruption also created electrical storms. The effects of the volcanic eru… The initial visual report of the eruption was at 23:52 GMT, when a red cloud was observed at the volcano, lightening up the sky above the eruptive site. The most recent began in December 1821 and lasted intermittently for more than a year. Volc., 68, 377-393, 2006.Pedersen, R., F. Sigmundsson,InSAR based sill model links spatially offset areas of deformation and seismicity for the 1994 unrest episode at Eyjafjallajökull volcano, Iceland, Geophys. ): Have been observed at over a hundred meters.Heading:Colour: White.Tephra fallout: None.Lightning: None were measured on the UK Met Office's system.Noises: No reports. Ríkislögreglustjórinn og Háskólaútgáfan. thesis, Faculty of Earth Sciences, University of Iceland. Overall assessment: The level of water in the crater lake only rose about 1 – 2 meters over the weekend. Ashfall was reported in Vik, southern Iceland on 8th May. This is due to the change in eruptive style – tephra is now not washed to the same extent by water in the eruptive plume.Amount of erupted material: Uncertain but on the order of 100 millon cubic meters. Lava flows short distance from the eruptive site, and minor eruption plume atelevation less than 1 km was deflected by wind to the west. The neighbouring volcano Katla erupted then on 26 June 1823. This will be good news for travelers because it will help clear skies over Europe. Earthquakes and Eruptions in Iceland 2010 from hjalli on Vimeo. Some may be waiting for more than a week to find available seats. April), two GPS stations located north (STE2) and south (THEY) of the summit crater moved rapidly toward the eruption site (about 6 cm contraction between stations). GPS deformation:The seismic activity beneath Mýrdalsjökull glacier does not appear to be related to inflation of the area. Material (tephra) in the ice cauldrons around the volcanic vents: 30 million cubic metres (39,000,000 cu yd) 2. An eruption began in South Iceland in late evening of 20 March 2010 at the Eyjafjallajökull volcanic system (also known as Eyjafjöll volcano – Global Volcanism Program Volcano number 1702-02=). When Eyjafjallajökull erupted in 2010, it clogged the atmosphere with so much volcanic ash that at one point the plume was grounding tens of … After ruling out the 300-foot Lagarfljóts worm, investigators concluded that only Grýla—best known for emerging from her cave at Christmastime in search of naughty children to stuff in a sack—possessed the power necessary to generate an eruption of Eyjafjallajökull's magnitude. Developments in Quaternary Sciences, vol., 13, eds. O By Olivier A. Tephra fall is minor or insignificant. The volcano continued to have several earthquakes daily, with volcanologists watching the mountain closely. Kamchatka Photos from Kamchatka : Kamchatka in Russia's far east is one of world's remotest regions and has an almost unparalleled density of active volcanoes. volcanolive.com In afternoon 22 April plume reached temporarily up to 6 km height, but was mostly at about 3 km level. Note that parts of the glaciers are greyish/black due to the ashfall (i.e. Water accumulation in the crater is slow as the ice is no longer in contact with hot material.
