Icelandic Volcano Appears on Verge of a Far More Powerful Eruption than Last Year

Bárdarbunga 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...
