2010 The Iceland Volcano Eruption.

Volcanic Eruption in Iceland Unlikely to Have

Global Effects• ScienceDaily (Apr. 18, 2010) — The

eruption of an Icelandic volcano that sent a huge plume of ash into the atmosphere and caused sweeping disruptions of air traffic over Great Britain and Scandinavia today will likely dissipate in the next several days, according to a University of Colorado at Boulder atmospheric scientist.

Volcanic Eruption in Iceland Unlikely to Have

Global Effects• Professor Brian Toon, chair of CU-Boulder's

atmospheric and oceanic sciences department, said the plume created by the eruption of the Eyjafjallajokull Volcano contains tiny rock particles made up of silicate and basaltic glass that can be extremely damaging to aircraft engines. Unfortunately, the plume is at about 30,000 feet -- the same altitude as jet aircraft fly -- and is directly in the flight path between New York and Europe, he said.

Global Effects• Toon said the amount of sulfur dioxide

spewed by the volcano so far poses no threat to world climate as determined by an instrument aboard NASA's Aura satellite. But he noted than an apparently larger eruption of an Icelandic volcano in 1783 --which was written about by Benjamin Franklin -- caused some climate issues in Europe by creating smog-like conditions in London that partially blocked out the sun and persisted through the summer months.

The volcanic eruption on Wednesday partially melted a glacier, setting off a major flood that threatened to damage roads and bridges and forcing hundreds to evacuate from a thinly populated area.

In this Wednesday April 14, 2010 photograph, smoke and steam are seen rising from the volcano under the Eyjafjalla glacier in Iceland, which erupted for the second time in less than a month, melting ice, shooting smoke and steam into the air and forcing hundreds of people to flee rising floodwaters.

This picture taken on March 27, 2010 shows lava spurting out of the site of a volcanic eruption at the Eyjafjallajökull volcano some 125 km east of Reykjavik . With lava still gushing, a small Icelandic volcano that initially sent hundreds fleeing from their homes is turning into a boon for the island nation's tourism industry, as visitors flock to catch a glimpse of the eruption.
