Iceland Volcano erupts (http://news.yahoo.com/s/ap/eu_iceland_volcano)

These pice of a news explain the eruption of a Iceland Volcano. The volcano name is Grimsvötn and began to erupt in 21 May 2011. Last year, in Iceland also a vulcano began to erupt (called Eyjafjallajökull). The Eyjafjallajökull eruption caused the close of air space for a week. This provoced the suspension of a lot of things like a MotoGP race in Japan. Also provocate that Barça went to Milano by bus for play the semi-final of Champions League. Other thing that 2010 eruption provocate were that in some places in Europe arrive the ash from Volcano. Some european people breath the toxic ash but that didn't cause any problem. 
The 2011 Iceland eruption, has not caused nothing yet. But it's possible, that ash arrive early to Europe. Experts says that next days ash will arrive to London. At the moment the eruption is more little than 2010 eruption.
I think that Grimsvötn eruption won't be more problematic than Eyjafjallajökull eruption but early we'll can't travel to places like London or Dublin.
