why did eyjafjallajökull erupt

Wiki User Answered . Still, why did Iceland’s Eyjafjallajökull cause so much trouble back then, and why even today are its other volcanoes often causing similar worries among airlines and … Why did the eruption happen? The cause of Eyjafjallajökull's explosive eruption seemed to be the meeting of one body of magma, made up mostly of the common volcanic rock … There … Answer. By comparison, Hekla is a mere infant at just 8800 years of age. The geologic processes that trigger an actual eruption are not yet well understood, says Feigl. The situation of a slowly growing magmatic intrusion inside a volcano can quickly go out of bounds if such an intrusion hits a body of magma of different composition — then a sudden explosive eruption can occur, as in Iceland earlier this year.". It started up again a few weeks later in June but the activity was very limited. 2010-12-10 09:45:01 2010-12-10 09:45:01. The last major eruption occurred in 1918, so it is long overdue. Over time, the earthquakes rose towards the surface, and land near the volcano rose at least 40 millimeters (2 inches)—both indications that magma was moving underneath the volcano. Eyjafjallajökull, however, maintained basically the same inflated shape through mid-April, when the first eruption ended. There was a problem. The last eruption in the Eyjafjallajokull glacier, in 1821, spread to Katla, causing serious flooding. The situation of a slowly growing magmatic intrusion inside a volcano can quickly go out of bounds if such an intrusion hits a body of magma of different composition — then a sudden explosive eruption can occur, as in Iceland earlier this year.". It then erupted in April, spewing a huge plume of ash that created phenomenal lightning displays, colored sunsets a fiery red across much of Europe, and forced flight cancellations for days. Live Science is part of Future US Inc, an international media group and leading digital publisher. The plate boundary is pulling apart at a rate of 2 cm a year. Rather, two or more discrete magmatic sources were involved, with magma of different composition.". The behavior of Eyjafjallajökull might be typical for such moderately active volcanoes. This time, the lava broke out through a new vent under the ice-capped summit of the mountain. The name Eyjafjallajökull is derived from an Icelandic phrase meaning … After a two-day pause, the volcano began to erupt again on April 22nd. Additional localised disruption continued into May 2010. Eyjafjallajökull actually lies away from the rift in the earth that other Icelandic volcanoes spring from and which is ultimately responsible for the island's existence. IE 11 is not supported. Convection currents are driving apart the North American plate and the Eurasian plate. When it comes to a typical eruption of highly active volcanoes, scientists have learned over the years that magma chambers within the volcano gradually fill up beforehand and rapidly deflate as pressure is released, deforming the surface. On the boundary can be found numerous volcanoes and these erupt fairly frequently. The eruption of Eyjafjallajökull was presaged by a series of earthquakes starting in early March. The 2010 eruption of Iceland's Eyjafjallajökull volcano had a huge impact on air travel, changing the assessment of risk by the aviation sector and catalyzing new lines of scientific investigation.

The 2010 eruptions of Eyjafjallajökull were volcanic events at Eyjafjallajökull in Iceland which, although relatively small for volcanic eruptions, caused enormous disruption to air travel across western and northern Europe over an initial period of six days in April 2010. As explosive as Eyjafjallajökull proved, it is actually only a moderately active volcano — that is, one that erupts once every few centuries or even millennia, explained volcanologist Freysteinn Sigmundsson at the University of Iceland. Why did Eyjafjallajokull erupt? However, the magma chamber that deflated in Eyjafjallajökull during the explosive April eruption was not the one that filled up right beforehand. The eruption also created electrical storms. As explosive as Eyjafjallajökull proved, it is actually only a moderately active volcano — that is, one that erupts once every few centuries or even millennia, explained volcanologist Freysteinn Sigmundsson at the University of Iceland.

Location : The eruption began on 20th March 2010 and ended 7 months later in October 2010. It lies where the Eurasian plate meets the North American plate. "The study gives the hope that with similar methods as we have used, we can better understand how volcanoes work and how they wake up before eruptions," Sigmundsson said. The country’s government, still reeling from the financial crisis, chose to bring in UK consulting firm Brooklyn Brothers to help mitigate the impact of the negative coverage. I guessed this in my homework: The volcano is located on a constructive plate boundary. "There was not one main magma chamber active under the volcano capturing magma in 18 years of unrest preceding the eruption, as is often envisioned in models for the most active volcanoes on Earth. Here, you can read more Eyjafjallajökull facts. During the eruption, almost all air traffic was canceled for the next 5 days, more than 100,000 flights. Please refresh the page and try again.

So how did Iceland turn things around? Why did Eyjafjallajökull erupt? "We're still trying to figure out what wakes up a volcano." From the initial eruptive activity at Eyjafjallajokull volcano in 2010, that was a lava producing eruption 20 March - 12 April, preceding the explosive eruption. It has been an active volcano since many decades. A phonecall in the dead of night was the first inkling the people living on the Thorvaldseyri farm had that Iceland's glacier-covered Eyjafjallajokull volcano was about to erupt. This enabled them to deduce how the volcano swelled to within a few millimeters accuracy due to the flow of magma within in the months before and after it became active. Eyjafjallajökull (also known as Eyjafjöll) is located west of Katla volcano. "Our research shows that mapping out magmatic plumbing systems is important to correctly interpreting potential precursors to eruption. The initial eruption caused a 500 metre fissure in a nearby pass. It then erupted in April, spewing a huge plume of ash that created phenomenal lightning displays, colored sunsets a fiery red across much of Europe, and forced flight cancellations for days. Eyjafjallajökull first erupted on March 20, 2010, in a fiery display that sent fountains of lava shooting high into the air and ribbons of lava flowing down cliff faces. "There are many such volcanoes in the world, including many on the circum-Pacific 'Ring of Fire' volcanic belt, including volcanoes in the U.S. West, Kamchatka [in Russia] and the Andes," Sigmundsson told OurAmazingPlanet. BGS scientists respond to volcanic eruptions and contribute to the Scientific Advisory Group in Emergencies (SAGE).
