Icelandic Volcano Appears on Verge of a Far More Powerful Eruption than Last Year
0 comments Posted by queen at 7:21 AMBárdarbunga dwarves the Eyjafjallajökull volcano,
which shut-down most of Europe's airspace in May 2010
Local experts have observed all the signs that another -much larger- Icelandic volcano is ready to blow, an event that could dwarf last year's series of eruptions that shut down air travel throughout Europe and changed weather patterns for months...
Geologists detected the high risk of a new eruption after evaluating an increased swarm of earthquakes around the island's second largest volcano.
Pall Einarsson, a professor of geophysics at the University of Iceland, says the area around Bárdarbunga is showing signs of increased activity, which provides "good reason to worry".
He told the country's national TV station that a low number of seismometer measuring devices in the area is making it more difficult to determine the scale and likely outcome of the current shifts. But he said there was "every reason to worry" as the sustained earthquake tremors to the north east of the remote volcano range are the strongest recorded in recent times and there was "no doubt" the lava was rising.
The geologist complained that the lack of coverage from measuring devices means he cannot accurately detect the depth and exact location of the increased number of localised earth movements.
.......
The last recorded eruption of Bárdarbunga was in 1910, although volcanologists believe its last major eruption occurred in 1477 when it produced a large ash and pumice fallout. It also produced the largest known lava flow during the past 10,000 years on earth.
It is the second largest volcano on Iceland and is directly above the mantle plume of molten rock.
By comparison, Bárdarbunga dwarves the Eyjafjallajökull volcano, which shutdown most of Europe's airspace last year after its ash cloud drifted across the continent's skies...

The Iceland volcano shows little sign of ending its current eruption, but winds that have shifted SE now are sparing European air travel, and all airports now open. But forecasters have now expressed additional reason for concern.
►Sunday May 16th update -here-
According to USA Today, Volcanic ash from the Iceland volcano could disrupt air travel in both Britain and Germany in the next few days. The British Department of Transport said there was a risk that parts of British airspace could be closed beginning Sunday and those problems could continue through Tuesday. The predictions are based on the continuing eruption of Iceland's Eyjafjallajokul volcano and current wind and weather conditions.

The Eyjafjallajökull volcano in Iceland shows little sign of ending an eruption that's causing havoc again in European airspace.... celebrities and media arriving in the French Riviera for the Cannes film festival now may have to arrive by boat, with the plume currently hanging over the Mediterranean. However, shifting winds could possibly spare European air travel by the weekend.
The ash cloud emanating from the Iceland volcano is ever changing in form and color, from dove grey to anthracite to brown... and sometimes even blueish when sulfur droplets are present. The form is dependent on the eruption intensity but also on the stability of the surrounding atmosphere. Unstable conditions favour an unsteady plume, even looping, but during high stability acessory clouds tend to acompany the plume, which then forms a billowing sheet downwind affecting visilibity and weather patterns thousands of km away.
This Iceland volcano May 13 update maps linked at the UK Met Office below shows where the plume is most likely headed today, according to the Icelandic authorities:
