Eyjafjallajökull Eruption – UPDATE Apr 18

Posted by feww on April 18, 2010

Eyjafjallajökull Eruption Intensifying

Fire-Earth can confirm that  the eruption at Eyjafjallajökull is intensifying with ash plume rising to a height of about 10km.

How Long Will Eyjafjallajökull Erupt

There is absolutely no reason why the explosive  activity at Eyjafjallajökull couldn’t go on for days, weeks even months. Not only Eyjafjallajökull could follow the “Chaitén pattern” and even trigger other, larger volcanoes like Kata to erupt. Indeed, there’s historic precedence for the latter scenario.

Iceland’s Meteorological Office agrees with Fire-Earth assessment.

“The eruption could go on like that for a long time,” geophysicist Bergthora Thorbjarnardottir at the Meteorological Office said.

UKMET: Update to Volcanic Ash Plume — 0851 on Sunday 18 April 2010

“Satellite imagery Sunday morning shows an active volcanic plume spreading ash southwards and southeastwards from southern Iceland. Remnants of earlier plume activity over Europe much less evident now on derived dust imagery. Recent information from the Icelandic Met Office suggests the volcano is currently erupting ash to a height of approximately 4km. Issued at 0850 on Sun 18 Apr 2010.”

‘Chaos’ as the volcanic ash from Iceland continues to move into Europe’s airspace

About 60,000 flight will have been canceled by Sunday evening (UTC) with an estimated 12 million air travelers stranded since Thursday.

Desperate Airlines ‘Daredevil Management’ May Well End in DISASTER

About 20 countries have closed their airspaces until late Sunday, some into Monday, leaving millions of passengers globally as ash clouds from Eyjafjallajökull eruption linger on in Europe’s airspace.

Dutch and German airlines have reportedly carried out test flights, apparently without any damage to the planes. The most obvious dangers of such recklessness are the facts that the concentration of airborne ash particles is neither uniform, nor constant. High concentration of ash may exists in air pockets that the test flights avoided, or changing wind patterns could increase the concentration of ash in an air route within minutes.

In fact the weather reports say the Icelandic ash concentration in the upper atmosphere may become more concentrated through Wednesday.

Airlines are desperate because, in addition to losing money for each flight canceled, their stock values are taking a nosedive, too. In fact some of the major carriers could lose by as much as 10 percent of their share values by Tuesday.

Why is volcanic ash so dangerous?

Volcanic ash is composed of small tephra, or tiny bits of pulverized glass and rock that are created by volcanic eruptions. The particles are usually accompanied by several gases including sulfur dioxide (SO2), which is mixed with water in the air and converted into droplets of sulfuric acid and other substances that are harmful to the plane. Volcanic ash is potentially deadly to aircraft and their passengers. It poses three types of danger to aircraft by way of:

  • Clogging the engine and causing engine failure
    • Clogging the fuel and cooling systems
    • Melting in the hot parts of the engine, and fusing on engine components thereby causing loss of engine thrust that could lead into a flame out, shutting down the engine
    • Breaking the blades and other sensitive components inside the turbine
  • Causing physical damage to various parts of the plane including abrasion of engine parts, the airframe, as well as control and steering mechanism
  • Reducing visibility

Few Facts about Icelandic Volcanoes

  • Iceland is home to about 130 volcanoes, 18 of which have erupted since about 1,000 years ago.
  • Eruption from Iceland’s volcanoes have produced more than 30 percent of the total lava output globally, since the 1500s.
  • The Laki eruption in 1783-1784 produced he largest volume of lava in the last 500 years.
  • An eruption of Eldgjá in 934 CE produced twice as much lava as did Laki.

Explosion at Laki (Lakagigar) Volcanic fissure

A destructive eruption at Laki volcano, which occurred over an 8-month period in 1783–1784, ejected about 14 cubic km (3.4 cu mi) of basalt lava and plumes of poisonous hydrofluoric acid and sulfur-dioxide gas that lead to a famine in Iceland. About a quarter of the population and half of all livestock perished. Dust clouds covered most of Europe and parts of Eurasia and Africa for a year.

Ragnarök [the End of the World]

Posted by feww on April 18, 2010

The sun turns dark

Earth sinks in the sea, the fair, bright stars disappear from the heavens

Ragnarök
The sun turns dark,
earth sinks in the sea,
the fair, bright stars
disappear from the heavens.
Sizzling blaze
around the tree of life
colossal heat plays with
the heavens. —Völuspá

The above stanzas were quoted from the famous Nordic poem Völuspá in the Iceland Review. Völuspá, Prophecy of the Völva, tells the story of creation of the world and how it comes to its end, and is arguably the most important source for understanding the Norse mythology.


Yggdrasil
, a modern representation of the world tree which is central to Norse mythology.  The world tree is a motif that appears in some Indo-European religions and mythologies. It is represented as a giant tree that supports the heavens, connects it to the earth, and the underground through its roots.

“It was like the sun had gone out in the middle of the day.”

Iceland Review editor Bjarni Brynjólfsson and photographer Páll Stefánsson wondered how it was to drive through the area affected by the eruption: “We tried driving into the darkness and it was like we had stepped into another dimension. We felt it was the end of the world as described in Völuspá, the old Icelandic Poem the tells the story of the end of the world called Ragnarök or Götterdämmerung in the famous opera by Wagner.” More …

Eyjafjallajökull Eruption Intensifies

Posted by feww on April 17, 2010

Webcams Show Heightened Activity

Eruption at Eyjafjallajökull has steadily Intensified in the past 3 hours

Eyjafjallajökull has resumed explosive activity in the past 3 hours, having earlier slowed down to sporadically ejecting single plumes of ash once every 2 to 3 minutes.

The following are latest images obtained from two webcams that are trained on Eyjafjallajökull at Valahnúk and Hvolsvelli stations. The images show a constant stream of ash, steam and fumes spewed from the Icelandic volcano.The images are provided by Míla ehf and may be subject to copyright.


Valahnúk Webcam freeze frame of Eyjafjallajökull at 08:55UTC .


Hvolsvelli Webcam Image of Eyjafjallajokull also recorded at 08:55UTC.

The following irregular sequence of images were recorded from Hvolsvelli Webcam.


[L-R and T-B] Freeze frames shows a large plume of ash, steam and gasses ejected from the volcano just after sunrise at 5;16UTC on April 17, 2010. The ash plume seen in the first frame above dispersed (second frame) within minutes of being ejected from Eyjafjallajokull; however, after a series of explosions that occurred about 30 seconds later, another plume was ejected out of the volcano’s crater. The new plume seemed to be slightly larger than the previous one. Click image to enlarge.

Another sequence of images recorded simultaneously from Hvolsvelli and Valahnúk Webcams.


[T – B] The above freeze frames were recorded at about 5:31UTC, showing single plumes of ash and gasses ejected from
Eyjafjallajokul. Click image to enlarge.


[T – B] The above freeze frames were recorded at about 5:35UTC. Most of the frames show two plumes, indicating a gradual increase in the frequency of eruptions at Eyjafjallajokul. Click image to enlarge.


This frame was recorded at 5:40UTC showing 3 plumes which meant the eruptions at Eyjafjallajokul had further intensified. Click image to enlarge.

Eyjafjallajökull – UPDATE Apr 17

Posted by feww on April 17, 2010

Eyjafjallajökull Still Erupting

40,000 flights grounded since Thursday to avoid engine failure from Eyjafjallajökull ash

A new round of flooding has affected the areas around Eyjafjallajokull, as hot gases from the volcano continue to break up and melt the glacier that covers it.

Huge volumes of floodwater and massive chunks of ice, some reportedly as large as 3-story apartment blocks, have forced about 1,000 locals to evacuate their homes, most of them for a second time in 3 days. The floodwaters have almost completely washed off a causeway along the flooded Markarfljot river, which was severely damaged in the first round of flooding.

According to a local report,  the eruption is somewhat weakening, and Eyjafjallajökull is producing less ash, for now.

Staff from the Icelandic Meteorological Office flew with the Icelandic Coast Guard to the Eyjafjallajökull eruption site on the afternoon of April 16th 2010. At 4 pm the volcanic ash cloud was clearly visible above the cloud deck, rising at times to at least 30,000 feet. Steady winds from the east-north-east moved the cloud away from the volcano. The cloud height was variable from 25 to 30,000 feet and its colour varied from dark to white, depending on how much ash was in the cloud. Credit: Icelandic Met Office.
