About 30 minutes ago, Health Protection Scotland and NHS National Services Scotland reported that the volcanic ash is now reaching ground level. The ashes will reach ground level over UK starting from Scotland, before moving south during the night. Anyhow, according to the same sources, the concentration of particles that will reach ground level at those distances will be likely low and should not cause serious harm.
And just a few minutes ago, IcelandReview.com reported that meteorologist Thorsteinn Jónsson at the Icelandic Meteorological Office said that ash emitted from the volcano in Eyjafjallajökull in south Iceland will continue to drift across Europe and spread to many countries in the next 24 hours. He added that it is likely that the eruption will continue with the same strength for an unforeseen period of time, thus causing ash to spread across the entire northern hemisphere.
Of course, ash fall in Iceland, not only in the immediate surroundings of the volcano, might be dangerous; if winds change direction, also Reykjavík will be affected. BBC has a video shot from their car this morning, in an area east of the Eyjafjallajökull glacier. Click here to view the video now.
RUV.is posted a comprehensive article, in English, informing people about precautions to take in case of ash fall in their area. We also found this good printable PDF document published by a U.S. Emergency Management Division. And do not forget the good old do-it-yourself guide we posted a few hours ago.
