Guðmundsson predicts that the flood would follow a northeasterly route along the river Jökulsá á Fjöllum. The AP reports that area roads are already being closed as a precautionary measure. The eruption took place in the lava field of Holuhraun northeast of the Bárðarbunga caldera proper. 101-119 View in supplementary information, The height of the plume was determined using the best–fit of wind direction measured by the DOAS traverse and the winds simulated by the HARMONIE meteorological model (Pálmason et al., 2013) with model level elevations between 1000 and 500 hPa (corresponding to the surface and 5600 m a.s.l considering a standard atmosphere). Observations of a substantial cloud-aerosol indirect effect during the 2014–2015 Bárðarbunga-Veiðivötn fissure eruption in Iceland Daniel T. McCoy 1and Dennis L. Hartmann 1Atmospheric Sciences Department, University of Washington, Seattle, Washington, USA Abstract The Bárðarbunga-Veiðivötn fissure eruption lasted from 31 August 2014 to 28 February 2015, View in supplementary information Iceland activated the National Crisis Coordination Center (NCCC) on August 20, 2014 to evacuate the area around the Barðarbunga volcano in the face of increasing earthquake activity in the region as they await an eruption and consider the implications for climatic impact. The eruption emitted large volumes of sulphur dioxide and impacted air quality in Iceland. { + qs; Rather, the airborne chemicals can damage the engines, clog ventilation and cause the aircraft to stall. If the Barðarbunga volcano ejects a column of ash particles and sulfuric gases, a hazy cloud could cover not only Iceland, but also the entire planet within weeks, blocking sunlight and causing global cooling according to Scientific American (SA). var params = Scientists are speculating about the climatic impact as Iceland awaits the Barðarbunga volcano eruption. })(document); Iceland Awaits Barðarbunga Volcano Eruption and Climatic Impact, Iceland Volcano Erupts for the First Time in 6,000 Years, Tina Turner Bids Fans Farewell to Battle PTSD, Stroke, and Cancer [Video], Deshaun Watson Exposes Himself to Sexual Assault Charges [Video], ‘The Conners’ Stage Crew Member Suffers Fatal Medical Event, Captain America Marvel’s New Cross-Over Hero [Video], Dick Hoyt Marathon Legend Who Ran With Disabled Son Dies at Age 80, Texas Waxworks Pulls Trump’s Figure After Repeated Assaults by Visitors, Indiana Police Confiscate Around $8 Million Worth of Marijuana, 12 Republicans Vote ‘No’ on Medals for Capitol Police Attacked on Jan. 6th, Scientists Grow Mouse Embryos in Artificial Womb. In some cases, airline disruptions due to volcanic activity can last much longer. There was no effect on flights outside of the immediate vicinity due to a lack of a significant emission of volcanic ash. The 2,000-meter tall Bárðarbunga volcano in Iceland is at risk of eruption, an event that could send a cloud of ash and steam high into the atmosphere and cause extensive disruptions in air travel, among other effects, according to media reports. Overall, the 2014–2015 eruption at Holuhraun was the largest tropospheric volcanic sulfur pollution event since the 2000–2003 eruption of Figure 1. Furthermore, volcanic eruptions can have a long-term effect on climate, producing either warming or cooling effects. Bárðarbunga system, a pre-publication extract from the Catalogue of Icelandic Volcanoes (pdf 0.9 Mb). ... the impacts have been minimal. View in supplementary information, The sample collection and analysis methods are based on an emergency response strategy and therefore the sampling method may have some weaknesses; 1) the frequency and constancy of sampling differs from site to site, 2) the samplers are open during the preceding dry–period so samples may be affected by dry deposition including basaltic glass, the most common dust material in Iceland (Arnalds et al., 2014) and, 3) most samples were sent to Reykjavík for analysis, in some cases with a delay of few days often caused by adverse local environmental conditions. The 2014–2015 Bárðarbunga‐Veiðivötn fissure eruption at Holuhraun produced about 1.5 km 3 of lava, making it the largest eruption in Iceland in more than 200 years. It is not visibility that worries pilots when ash clouds fill the air, explains The Weather Channel. Schmidt A, Leadbetter S, Theys N, et al (2015) Satellite detection, long-range transport and air quality impacts of volcanic sulfur dioxide from the 2014–15 flood lava eruption at Bárðarbunga (Iceland). var qs = Object.keys(params).reduce(function(a, k){ a.push(k + '=' + encodeURIComponent(params[k])); return a},[]).join(String.fromCharCode(38)); View in supplementary information, The water concentration in the gas was calculated indirectly by measuring the relative humidity, pressure, and temperature (Tamburello, 2015). Those that do not fall to earth and dissipate within days or weeks can contribute to global climate change. 105 kg s-1. Warning: A fissure eruption has started north of Dynjujökull. (2015). 2014-15 Eruption A subglacial eruption began at Bárðarbunga volcano at 11:18 on 23rd August 2014.A magnitude 5.3 earthquake hit under volcano on 24th August 2014. id: "440c396f-3561-4a33-985f-879a46a8d585", The effusive six months long 2014‒2015 Bárðarbunga eruption (31 August‒27 February) was the largest in Iceland for more than 200 years, producing 1.6 ± 0.3 km 3 of lava. On the Bárðarbunga gradual caldera collapse - An article in Science. FULL PAPER: Understanding the environmental impacts of large fissure eruptions: Aerosol and gas emissions from the 2014–2015 Holuhraun eruption (Iceland) The most impactful in recent years was the 2010 Eyjafjallajökull eruption which produced … Seismic tremor was observed on all seismic stations and the web camera installed in the area by Mila has showed some nice pictures of the eruption. During the first weeks, the flow rate was two to three times the average (2.5), while 50-80 m3 s-1 occurred in December and January (0.65 times the average), followed by gradual decline in February leading to the termination on 27 February. cb: (new Date()).getTime() On August 17th 2014, an eruption that is still ongoing started under the Bárðarbunga system. Galeczka Iwona, Gunnar Sigurdsson, Eydis Eiriksdottir, Eric Oelkers, Sigurdur GislasonThe chemical composition of rivers and snow affected by the 2014/2015 Bárðarbunga eruption, Iceland Journal of Volcanology and Geothermal Research, 316 (2016), pp. d: "Z3VhcmRpYW5sdi5jb20=", By increasing volcano surveillance and activating extra seismic monitors, officials are adding layers of protection to allow them to give the people of Iceland as much advance warning as possible of an imminent eruption so they can take any necessary protective measures. Apart from the emission of volcanic gas, the hazard during the 2014–2015 volcanic eruption in the subglacial Bárðarbunga volcanic system was the large-scale effusion of lava (Gíslason et al., 2015) as well as the likelihood of a devastating glacier flood, also referred to as “Jökulhlaup” (Björnsson, 2003).
