Iceland Volcanic Eruption

Amazing pictures from the recent volcanic eruption in Iceland

Major volcanic eruptions have started at Eyjafjallajökull in Iceland. The 5,500-foot volcano started erupting 20 March 2010. A later eruption from 14 April 2010 has disrupted air travel in Europe.

Huge, high altitude plume of volcanic ash have forced many airports to close down, thus spreading panic and fear among passengers.

The World Health Organization has also warned of potential health risks if a person is exposed to volcanic ashes for a long time.




Clouds forming from the pyroclastic eruption are clearly visible.  These clouds are initially made up of mostly dust particles less than 1/100 inch in diameter as well as ash fragments less than 1/5 inch in diameter. These dust particles may be carried great distances. In a powerful eruption they may be carried around the earth several times.  Most volcanic ash however falls to the surface and are cemented together by water to form a rock called volcanic tuff.






















Lightning at Iceland Volcano

Intense lightning storms mixed with ash clouds to electrify the night sky over Iceland's Eyjafjallajökull volcano on Sunday.

The big clean up operation begins clearing away volcanic ash deposits.
