eyjafjallajökull volcano type

The IAVCEI Commission on Volcanic Hazards and Risk has a, Middle InfraRed Observation of Volcanic Activity (. J., and Kjr, K.H., eds., The Mrdalsjökull Ice cap, Iceland - Glacial processes, sediments and landforms on an active volcano: Developments in Quaternary Sciences, v. 13, p. 5-12. It’s probably become the world’s most famous volcano, after Mount Vesuvius in Italy. Geological map of Iceland, sheet 6, south Iceland. The first reports described incandescence reflected from a cloud above the eruption area, a 2-km-wide ice-free pass between Eyjafjöll and Katla volcano (with its overlying Myrdalsjökull ice cap). Steam and ash plumes continued to rise from the crater. By 23 June 2010, the Iceland Meteorological Office (IMO) and the University of Iceland Institute of Earth Sciences (IES) ceased issuing regular status reports. Explosions were also heard at locations 10-15 km NW. Steam rose from the crater, punctuated by a few small ash-bearing explosions, and a sulfur odor was strong nearby. Expand each entry for additional details. Several small and shallow earthquakes under the volcano occurred on a daily basis. | October. The second eruption occurred within the initially ice-covered caldera of Eyjafjallajökull. Conditions on 3 May were similar. Plumes drifted SW during 4-5 June and S during 6-7 June at altitudes of 3-6 km (9,800-19,700 ft) a.s.l. This compilation of synonyms and subsidiary features may not be comprehensive. According to a news article from 27 October, a scientist at the University of Iceland Institute of Earth Sciences noted that the eruption of Eyjafjallajökull, that began as a fissure eruption on 20 March 2010 and later continued from the summit caldera on 14 April, was over. There’s even a YouTuber that goes by the name of The Magnus Effect who posted a short video on the topic. Incoherent areas are masked. Remarks: GPS and InSAR data reveal a pre-eruptive stage of inflation due to a complicated time-evolving magma intrusion that produced variable and high rates of deformation, in particular after 4 March. In addition to discussing the eruption and its final stages, this report also cites a small sample of abstracts and papers from the numerous conferences, sessions, and publications that have thus far emerged on the eruption. The summit area was still steaming and geothermally active, and the eruption channel was still very hot in October 2010 (figure 18). Records show eruptions in 920, 1612 or 1613, 1821–23, and 2010. On 17 April the ash plume rose to over 8 km altitude, blowing first to the E, and then, after about 0341 that day, blowing to the S. Ash fell around the volcano and there were at least 115 lightning strikes in vicinity of the eruption. Ashfall was noted 65-70 km ESE, and ash plumes were seen over the village of Vík, 40 km SE. Eyjafjallajökull volcano represents something bigger. Hooper, A., Pedersen, R., and Sigmundsson, F., 2009, Constraints on magma intrusion at Eyjafjallajökull and Katla volcanoes in Iceland, from time series SAR interferometry, p. 13-24 in Bean, C.J., Braiden, A.K., Lokmer, I., Martini, F., and O'Brien, G.S., eds., The VOLUME project - Volcanoes: Understanding subsurface mass movement: School of Geological Sciences, University College Dublin. The eruption plume was seen in satellite imagery as far as 200 km from Eyjafjallajökull on both days. It all started on March 20th, 2010. Iceland is one of the few parts of the MAR that we can see above sea level. Eyjafjallajokull is a strato volcano. The Institute of Earth Sciences at the Nordic Volcanological Center (NVC) reported that the summit eruption from Eyjafjallajökull continued during 21-27 April. On 5 April, eruption tremor (at 1-2 Hz recorded at the nearest seismic station, Godabunga) began to gradually decline. Intense steam rose from the craters, with occasional small ashy explosions. In April 2010, Eyjafjallajökull, a volcano in southern Iceland, began spewing several kilometres of volcanic ash into the atmosphere.The cloud of ash forced the greatest airspace closure since World War II, cancelling nearly 100,000 flights and disrupting the travel plans of tourists and business travelers alike throughout northern Europe. There was, however, a bit of an aftermath as far as Eyjafjallajökull environmental effects are concerned. Ash generation continued at a similar level. After apparent cessation of the fissure activity on or about 12 April, a second phase of the eruption began on 14 April (figures 2 and 3, table 1), generating ash plumes that blew E to Europe and resulted in a 20-80% decrease of airline flights for as much as a week (Wall and Flottau, 2010). Iceland is not a country that appears on the news frequently. The role of internal pathways was much less noticeable, yet an important contribution to the overall growth of the flow field as it fed significant surface breakouts emerging on the surface of what otherwise looked like stagnant lava. The vents were surrounded by 60-80 m high ramparts and the level of lava stood at approximately 40 m. This high stand led to opening of a new fissure trending northwest from the central segment of the original fissure. Venting at Fimmvörðuháls took place on an exposed ridge cropping out in a region with extensive glaciers to the E and W. Eruptions began in the initially ice-capped summit crater of Eyjafjallajökull on 14 April 2010 (BGVN 35:03 and 35:04). Phreatomagmatic activity with some lava spatter occurred from the northernmost of two craters in the summit caldera, generating plumes to an altitude of 3 km (9,800 ft) a.s.l. As of late May the eruption continued, with occasional plumes that restricted air travel in parts of Europe. Deformation of Grímsvötn volcano, Iceland: 1998 eruption and subsequent inflation. The, There are small mountains leading up to and surrounding the volcano. Over the next few days there was little change, with the N crater remaining active, generating mild explosive activity and spatter. The eruption continued during 23-24 March. Steinthorsson S, et al., 2002. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility. Now try saying that three times fast! News outlets reported that two people had died during the journey back from seeing the eruption. Glacier outlined in black. The grain sizes of the second phase of the eruption were quantified by The Environment Agency of Iceland; other data courtesy of IMO and IES. The tongue-twisting pronunciation of this Icelandic legend has humbled even the most talented of polyglots. Eyjafjallajökull, lying in south-west of Iceland, is a volcano covered by an ice cap. Eyjafjallajokull volcano, Icelandic volcano whose name is derived from an Icelandic phrase meaning ‘the island’s mountain glacier.’ Lying beneath Eyjafjallajökull (Eyjafjalla Glacier), its summit rises to 5,466 feet (1,666 meters) above sea level. Iceland rests along the Mid Atlantic Ridge, a divergent tectonic plate boundary at the bottom of the Atlantic Ocean. There are two other volcanoes in the same area, which makes the landscape truly stunning. Sources: Institute of Earth Sciences; Associated Press; Iceland Review. (h)? What type of volcano is Eyjafjallajokull? A strong smell of sulfur came from around the craters. a mixture of melt water & ash from the volcano Part of the glacier melted due to the heat of the eruption! Loughlin, S., 2010, Modelling of Iceland volcanic ash particles, news item from British Geological Survey (URL: http://www.bgs.ac.uk/research/highlights/IcelandAshParticles.html?src=sfb). Bull Volcanol, 68: 377-393. The ash was dominantly glass of andesitic composition (57-58% SiO2). The aggregation could have resulted from a number of mechanisms, including electrostatic attraction, particle collisions, condensation of liquid films and secondary mineralization. The 15 April radar image helped depict a series of vents along a 2-km-long, N-oriented fissure. Lava flowed a short distance from the eruptive site and a minor eruption plume rose to less than 1 km altitude and blew W. Tephra fall was minor or insignificant. A geophysicist noted that seismicity was gradually decreasing. Table 2. Ash plumes rose above the crater; ashfall was seen on the W flanks and in an area about 32 km W. The next day the eruption plume was not visible, but likely did not exceed an altitude of 3.6 km (11,800 ft) a.s.l. Lava descending gullies generated zones of frothy rock. The lava flow stopped advancing, and very little steam rose from the edges of the flow. Temporal development of the 1999 intrusive episode in the Eyjafjallajokull volcano, Iceland, derived from InSAR images. Pedersen, R., and Sigmundsson, F., 2004, InSAR based sill model links spatially offset areas of deformation and seismicity for the 1994 unrest episode at Eyjafjallajökull volcano, Iceland: Geophysical Research Letters, v. 31, L14610 doi: 10.1029/2004GL020368. If that’s not a bucket list item, then I don’t know what is. Eyjafjallajökull Volcano is located in South Iceland, about 100 miles (160 km) from Reykjavik. 5977, p. 410-411. At any rate, picturing three words makes it easier to remember. Bonadonna, C., Folch, A., and Loughlin, S., 2011, Future Developments in Modeling and Monitoring of Volcanic Ash Clouds, Eos, Transactions of the American Geophysical Union (AGU), v. 92, no. During the summit eruption (beginning 14 April 2010) gradual contraction of a source, distinct from the pre-eruptive inflation sources, was evident from geodetic data. What type of volcano is Eyjafjallajokull? Although the volcano has erupted during historical time, it has been less active than other volcanoes of Iceland's eastern volcanic zone, and relatively few Holocene lava flows are known. Eruption from Fimmvörðuháls. On 18 May an ongoing explosive eruption plume was mostly steady at 7 km altitude; the rate of magma eruption was over 200 tonnes/second. On 31 May and 1 June, widespread drifting of existing ash was noted in SW Iceland. What follows is a mere sample of the available resources, many of which emphasized plume research. Sturkell, E., and P. Einarsson, F. Sigmundsson, S. Hreinsdottir, and H. Geirsson, Deformation of Grímsvötn volcano, Iceland: 1998 eruption and subsequent inflation,, 2003. Gislason, S.R., Hassenkam, T., Nedel, S., Bovet, N., Eiriksdottir, E.S., Alfredsson, H.A., Hem, C.P., Balogh, Z.I., Dideriksen, K., Oskarsson, N., Sigfusson, B., Larsen, G., and Stipp, S.L.S., 2011, Characterization of Eyjafjallajökull volcanic ash particles and a protocol for rapid risk assessment, Proceedings of the National Academy of Sciences, v. 108, no. | June During this time, the plume was darker and wider than in the preceding week. According to Sturkell and others (2009), "In 1994, and again in 1999, magma intrusion was detected under the southern slopes of Eyjafjallajokull. Eyjafjallajökull is one of the few stratovolcanoes found in Iceland. sport aircraft, Abstract, Session 1.3, p. 229, Cities on Volcanoes 6 Conference (URL: http://www.citiesonvolcanoes6.com/ver.php). On 11 April, eruption tremor also approached pre-eruptive levels, but visual observation revealed eruptive activity in late afternoon. The rising magma in the mantle puts pressure on the rocks above it, which is why we have wonders like the, They dominate the landscape and can be seen from several kilometers away. Ashfall was reported in areas to the S, NW, and N. On 19 May heavy rainfall combined with ashfall to cause a mudslide in a local river. Lava flowed S of the fissure into a canyon causing steam to rise from where the lava interacted with snow and ice. IAVCEI, 1973-80. It’s where the North American and Eurasian plates meet, and runs for 10,000 km (16,000 miles) along the ocean floor. Despite the fact that the eruption and subsequent volcano plume were terrifying, we are very lucky that the Eyjafjallajökull death toll was zero. During an initial eruptive phase from 20 March to 12 April 2010, lava flowed from fissures on Eyjafjallajökull's ENE flank. As noted below, during June 2010, hot lava could still be seen in cracks in the cooled rock on Fimmvörðuháls, and inside craters, but that was not the case at the ice-engulfed summit caldera. a, TerraSAR-X interferograms from descending satellite orbits, spanning the pre-eruptive intrusive period (left, time period 25 September 2009 to 20 March 2010 at 7:49 GMT) and the initial days of the explosive eruption (right, time period 11 to 22 April 2010). Activity continued during 16 April at a similar level as the previous day, with ash generation and pulses of meltwater causing jokulhlaup/lahars in the evening. Initially (20-25 March), the lava advanced towards northeast, but on March 26 the lava began advancing to the west and northwest, especially after April 1 when the activity became concentrated on the new fissure. A report on 2 May stated that during the previous 2-3 days ash plumes had become darker and wider than in the preceding week, explosivity had increased, and tephra fall-out had increased. In the weeks prior to the eruption, there was rapid deformation at Skogaheidi (SKOG; S of the volcano) and Steinsholt (STE1 and STE2; N of the volcano). By comparison, Hekla is a mere infant at just 8800 years of age. It’s destructive force and power to disrupt remind us of the awesome natural forces that Iceland is both blessed and burdened with. Scientists conducting an overflight saw a new 2-km-long, N-S-trending fissure, and ashfall to the E. About 700 people were ordered to evacuate the area, and certain flights were banned from flying N and E of the eruption area. Iceland’s Eyjafjallajökull Volcano burst into life for the first time in 190 years on March 20, 2010. By 9 April, after little change in deformation rates during the eruption, time series at continuous GPS stations N of the volcano showed sudden change, partly jumping back to pre-eruptive levels. It is a relatively small volcano, and is located W of Katla volcano. Of course, you obviously can’t drive right up to a glacier volcano. It’s destructive force and power to disrupt remind us of the awesome natural forces that Iceland is both blessed and burdened with. Investigators expected that cooling to ambient temperatures would take a few years . Volcanic hazards in Iceland. Evidence for this was the onset of semi-continuous discharge of meltwater from Gígjökull, steam rising from the N margin of the ice cauldron, and variations in tremor amplitude. No further lengthening of the fissure was detected. In 1967, there was a massive landslide on the Steinholtsjökull glacial tongue. All images cover the area shown in Figure 1B. The Institute of Earth Sciences at the Nordic Volcanological Center (NVC) reported that a new set of craters opened in the early morning of 14 April under the ice-covered central summit caldera of Eyjafjallajökull. Sturkell, E., Einarsson, P., Sigmundsson, F., Hooper, A., Ófeigsson, B.G., Geirsson, H., and Ólafsson, H., 2009, Katla and Eyjafjallajökull volcanoes, p. 5-12 in Schomacker, A., Krüger.

According to Gudmundsson and others (2010b) the summit eruption produced 0.1-0.2 km3 (dense rock equivalent) of tephra. Gislason and others (2011) reported on analyses of two sets of fresh, comparatively dry ash samples that fell in Iceland and were collected rapidly on 15 and 27 April, during more and less explosive phases, respectively. Conference field trip. Iceland’s landscape and history are inextricably linked to volcanoes. The northernmost one of two main craters in the summit caldera was active, and phreatomagmatic explosions occurred with some lava spatter at craters. Lava flowed a short distance from the fissure and a minor plume rose 1 km and drifted W. Tephra fall was minor or insignificant. Further References. The eruption was visually confirmed early in the morning on 14 April; an eruption plume rose at least 8 km above the glacier. There’s a lovely museum close to Eyjafjallajökull dedicated entirely to volcanoes in Iceland. Iceland is actually splitting in two, thanks to the separation of the tectonic plate boundaries. A new crater was seen in the W part of the caldera at the site of the new explosive activity. Due to the expanse and wide reach of the Eyjafjallajökull ice cap, there are many different outlet glaciers. Pulsating activity with small discrete explosions every few seconds. Black hardened lava, volcanic ash, pumice rock, and tephra fragments all combine to form different stratified colors and textures. They found the ash particles especially sharp and abrasive over their entire size range, from submillimeter to tens of nanometers. Scientists noted increased tremor on 4 June and a black plume that rose to an altitude of 4.5 km (14,800 ft) a.s.l. As compared with the same day of the previous week, flights decreased from about 27% on 15 April 2010 to almost 80% on 17-18 April, returning to 21% by 22 April. Reports are organized chronologically and indexed below by Month/Year (Publication Volume:Number), and include a one-line summary. The Icelandic Met Office reported that around 1900 on 31 March a new fissure at Eyjafjöll opened NE of the first fissure that began erupting on 20 March. As activity on the new fissure intensified, the discharge from the original fissure declined and stopped on April 7. Favorable wind conditions allowed traverse measurements under the gas plume with a DOAS spectrometer for SO2 flux estimates. Lava had traveled 4 km N from the crater, and lava was ejected a few hundred meters from the crater. De gletsjer Eyjafjallajökull is een van de kleinere gletsjers op IJsland en heeft een oppervlakte van ongeveer 100 km². A previous issue of the Bulletin (BGVN 35:03) contained an alternate model by Paul Einarsson. This caused ice and snow to rapidly melt, which led to massive flooding. Volcanic tremor was still higher than before the eruption, being rather steady since 22 May, but small pulses, mostly on the lowest frequency, were detected. And it’s all topped off by an extensive glacier. In the past, the UK has been affected by volcanic eruptions in Iceland, the most notable being the 2010 Eyjafjallajökull and 2011 Grímsvötn eruptions, which resulted in disruption of air traffic in the North Atlantic and Europe. From this they computed an average emission rate of ~ 15 m3/s.

Precursory observations. 2973-2989. The superheated lava also quickly melts the ice of the glacier and can cause flash flooding. Red stars and triangles same as in Fig. The tallest new cone reached an elevation 1,067 m, ~ 82 m above the previous ground surface. When IES surveyed the new landscape on 7 April (figure 9), they found 1.3 km2 of new lava, an average thickness of new lava there of 10-12 m, and an estimated volume of eruptive material of 22-24 x 106 m3. It’s eyja (islands) + fjalla (mountains) + jökull (glacier), which pretty much describes exactly what it is. The result is that Iceland has a lot of volatility in terms of eruptions and volcanic events. Different parts of … It’s probably become the world’s most famous volcano, after Mount Vesuvius in Italy. How many people can say they’ve seen an active volcano covered by a glacier? The second eruption saw volcanic ash shot many kilometers upwards as it spread in the Earth’s atmosphere. 21, Abstract V53F-01, 2010 Fall Meeting, AGU, San Francisco, Calif., 13-17 December (URL: http://www.agu.org/cgi-bin). Later in the afternoon reports indicated maximum plume height around 4.6 km with ash clearly visible in the clouds. When one is found the date, time, location, and intensity are recorded. 426-430. Sigmundsson and others (2010) noted that the 2010 eruptions came after 18 years of intermittent volcanic unrest. The eruption broke out with Hawaiian-style fire fountains (figure 5) on a ~ 500-m-long, NE-oriented fissure (at 63° 38.1' N, 19° 26.4' W). The left-hand image is the true-color RGB (red-green-blue) composite and the right-hand image is a false-color composite; in the right-hand rendition the ash plume appears red and the ice-rich clouds appear blue. Analogous conditions continued to exist for the following week. However, as the eruption onset neared, geophysicists saw both the depth of earthquakes decrease and the locations of earthquakes move from the area under the summit towards the Fimmvörðuháls site. Two or three plumes were observed (one at the eruptive craters, others more pronounced in front of the advancing lava). On 15 April the ash plume reached a maximum altitude of over 8 km.

Flights from Iceland's airports were again disrupted. Steam plumes rose above the lava that advanced N down the Gígjöjkull Glacier. Thick lines below indicate the time span of the interferograms. It is the most southerly volcano on mainland Iceland before Surtsey in the sea to the south west. On 4 May a flight by the Icelandic Coast Guard showed that the crater continued buildup in the northern-most ice cauldron. 2245-2279. According to Wall and Flottau (2010), more than 100,000 flights were canceled after the ash plume caused aviation authorities in many parts of Europe to close their airspace for several days. Post-Miocene Volcanoes of the World. Interestingly enough, the southern side of the mountain used to be a part of Iceland’s coastline. Now that we’ve covered some Eyjafjallajökull facts and the Eyjafjallajökull meaning and pronunciation, you’re ready to go. Black orthogonal arrows show the satellite flight path and look direction. Synonyms of features appear indented below the primary name. Most of us know the name Eyjafjallajökull for exactly this reason. Carn, S.A., Karlsdottir, S., and Prata, F., 2010, The 2010 Eruption of Eyjafjallajokull: A Landmark Event for Volcanic Cloud Hazards I, II, and III, Abstracts V41E, V53F, and V54C presented at 2010 Fall Meeting, American Geophysical Union, San Francisco, CA, 13-17 December 2010 (URL: http://www.agu.org/meetings/fm10/program/index.php). A stratovolcano is built by layers of hardened lava, tephra, pumice, and volcanic ash. Eruption tremor remained unchanged. Flentje, H., Claude, H., Elste, T., Gilge, S., Köhler, U., Plass-Dülmer, C., Steinbrecht, W., Thomas, W., Werner, A., and Fricke W., 2010, The Eyjafjallajökull eruption in April 2010 - detection of volcanic plume using in-situ measurements, ozone sondes and lidar-ceilometer profiles, Atmospheric Chemistry and Physics, v. 10, pp. NASA analysts determined that the ash plumes were at two different altitudes, the narrow, more concentrated plume was above the more diffuse cloud, casting a shadow on the ash below. Jokulhlaups (floods of meltwater) reached the lowlands around the volcano with peak flow around noon, damaging roads, infrastructure, and farmlands. A pulsating eruptive column reached above 8 km altitude, and lightning was frequently seen within the plume.Over the first 72 hours of explosive activity, scientists estimated that the eruption had produced 140 million cubic meters of tephra. IES reported that by 11 June 2010 a lake about 300 m in diameter had formed in the large summit crater, and by 23 June water was slowly accumulating in the crater because ice was no longer in contact with hot material. The ice cap covers an area of about 100 square kilometres (39 sq mi), feeding many outlet glaciers. The time span insets show the relation to the period(s) of elevated seismic activity (Dark gray main seismic period; Light gray secondary seismic period). Recent precursory intrusions. Preliminary data regarding the 2010 eruption of Eyjafjallajökull, which started at an E-flank vent (Fimmvörðuháls) and then later shifted to the ice-covered summit caldera. Lava was still limited to the immediate surroundings of the eruptive craters (runouts of less than few hundred meters). While they are not part of the same volcanic system, they are within 23 km (14 miles) of each other. An ash plume rose to more than 8 km altitude, and was deflected to the E by winds. But officials didn't order evacuations because the seismic hints weren't that dire. and drifted ESE, SE, and S. The cinder cone in the summit crater continued to build and was near the level of the ice on the crater rim on 8 May.On 5 and 6 May explosive activity increased and effusive activity decreased, resulting in higher eruption plumes and increased tephra fallout. The next day there was some variability in seismic tremor and tephra generation, but overall the activity remained stable. Meltwater descended in batches into rivers valleys, and seismometers recorded relatively steady eruption tremor. In addition, several other papers relevant to the eruption were presented during this meeting, as well as at the Annual Meeting of the American Meteorological Society (AMS) in Seattle, WA, in January 2011, and at the European Geosciences Union (EGU) 2011 General Assembly in Vienna, Austria. 2003; Pedersen and Sigmundsson 2006.

Chivers, H., 2010, Dark Cloud: VAAC and predicting the movement of volcanic ash, Meterological Technology International, June 2010, pp. At 22:30 on 20 March seismicity slightly increased and, within the next two hours, reports of a volcanic eruption were received. Increased seismicity up to 13 May suggested that new material was intruding from depth, and GPS observations indicated inflation. Radar images acquired that day by the Icelandic Coast Guard showed no changes in the size of the cauldron since 19 April. On 16 April some variability occurred in seismic tremor and tephra generation, but overall the eruptive pace remained stable and large closures of airspace continued. In fact, many geologists theorize that Iceland was actually formed directly as the result of underwater volcanic activity. Some local roads were closed and about 500 people living in nearby areas were evacuated. Ripley, T., 2010, Cloud Busting: How the UK is tracking the volcanic ash cloud, Meterological Technology International, June 2010, pp. The lava flow front had advanced 1 km N from the vents. The eruption plume height was unknown due to meteorological cloud cover at 5.3 km (17,400 ft) a.s.l. This forces 800 people to evacuate from the area. Hekla, Eyjafjallajokull, Katla, and Grimsvotn all form part of a chain of volcanoes running along the South and up through the Highlands. d) Which area of the island was worst affected by the Lava flow?
