Ash from the volcanic eruption in Eyjafjallajökull, south Iceland, in 2010 scattered widely and spread as far south as the Czech Republic and Switzerland.

Ash from the 2011 eruption in Grímsvötn, Vatnajökull, also traveled long distances, though not as far as that of the previous eruption; ash from Grímsvötn fell in Scotland and the Shetland Islands, Morgunblaðið reports.
Dr. John A. Stevenson, a scientist at the geological department at the University of Edinburgh, gave a presentation at the Nordic winter conference of earth scientists held at Harpa, the concert and conference hall in Reykjavík, yesterday.
Dr. Stevenson discussed a study of the ash fall from the two aforementioned eruptions conducted in the UK.
He also mentioned that Italian and Polish scientists claimed to have detected ash from Eyjafjallajökull traveling in the stratosphere above their respective countries with laser detectors but there was no known ash fall there.
The conference begun yesterday and concludes on Thursday.
