Iceland’s Grimsvotn Erupts Sunday May 21, 2011

Iceland’s Grimsvotn erupts again, and while some link it to recent Judgement Day fears, this is somewhat normal activity for the active volcano.

REYKJAVIK, Iceland – An Icelandic volcano was flinging ash, smoke and steam miles (kilometers) into the air Sunday, dropping a thick layer of gray soot in an eruption far more forceful — but likely far less impactful — than the one that grounded planes across Europe last year.

The country’s main airport was closed and pilots were warned to steer clear of Iceland as areas close to the Grimsvotn (GREEMSH-votn) volcano were plunged into darkness. But scientists said another widespread aviation shutdown is unlikely, in part because the ash from this eruption is coarser and falling to Earth more quickly.

The volcano, which lies beneath the ice of the uninhabited Vatnajokull glacier in southeast Iceland, began erupting Saturday for the first time since 2004. It was the volcano’s largest eruption in 100 years.

The ash from Grimsvotn — about 120 miles (200 kilometers) east of the capital, Reykjavik — turned the sky black Sunday and rained down on nearby buildings, cars and fields. Civil protection workers helped farmers get their animals into shelter and urged residents to wear masks and stay indoors. No ash fell on the capital.

Scientists said the eruption was unlikely to have the same global impact as last year’s eruption 80 miles (130 kilometers) away at the Eyjafjallajokull (pronounced ay-yah-FYAH-lah-yer-kuhl) volcano, which left 10 million travelers stranded around the world.

“It is not likely to be anything on the scale that was produced last year when the Eyjafjallajokull volcano erupted,” University of Iceland geophysicist Pall Einarsson told The Associated Press. “That was an unusual volcano, an unusual ash size distribution and unusual weather pattern, which all conspired together to make life difficult in Europe.”

Still, Icelandic air traffic control operator ISAVIA established a 120 nautical mile (220 kilometer) no-fly zone around the volcano, closed Keflavik airport, the country’s main hub, and canceled all domestic flights. It said Keflavik would stay shut until at least noon Monday, canceling about 40 international flights.

Trans-Atlantic planes — including Air Force One, due to carry President Barack Obama to Ireland later Sunday — were told to stay away from Iceland.

The European air traffic control agency in Brussels, Eurocontrol, however, said there was no impact on European or trans-Atlantic flights further south and said it did not anticipate any impact through Monday.
