The volcano is still going strong but the ash is turning more coarse,
and is falling again on the farms south of the glacier. A hard times it has given the folks and livestock there. Lava is flowing down and under the glacier melting the ice and thats the white smoke seen on the camera. The wind forcast for next 3 days is west and north westward so it might disturb flights in Scotland if it blows that far. good visability in the web camera fram this angle http://eldgos.mila.is/eyjafjallajokull-fra-valahnjuk/ Thor, Reykjavik. |

Iceland Review seems to think the chances of flight disruption are
slim with the change in ash characteristics : http://icelandreview.com The ash being emitted is much coarser than it was during the first days of the eruption. The fine particles that caused the most disturbances in the upper atmosphere, and thus disrupted flights, have disappeared. Oddsson was on a team of scientists who traveled up to Eyjafjallajökull on Wednesday to collect samples from the ash which is currently being emitted from the crater. The geologists said they walked into a rain of volcanic debris. “We didn’t go so far that we were at risk of being hit by boulders, only smaller rocks and grains. You could feel them hit your shoulder.” For the most part, domestic and international flight schedules in Iceland returned to normal yesterday after the airports in Reykjavík and Keflavík reopened. “It is running like a well-oiled machine,” commented Hjördís Gudmundsdóttir, information office at ISAVIA. It doesn’t appear as if the ash from Eyjafjallajökull will disrupt flights in the coming days. Yet there is nothing to indicate that the eruption is coming to an end; magma flow and the size of the volcanic cloud is about the same as it has been in the past days, ruv.is reports. |

Yesterday a team from the 60 minutes tv show went up there, and without a permission from the local police, the team came back unharmed and the American viewpoint can bee seen on the program sometime in the future. Saw a glass full of the first ash, it was wet but unlike clay it was rock hard, a nasty stuff indeed. Ash cloud is going south east towards the british isles, but still unclear how far it will go. But it the euruption is still going strong as seen on this web cam Hopefully working outside Iceland http://www.vodafone.is/eldgos Thor,Reykjavik. |

But it the euruption is still going strong: http://www.vodafone.is/eldgos The initial phases of eruptions are always the worst for VAAC as the volcano contains the full water table. Once that has dispersed, the residue ash production relies on the ground water inflow. It is probable that eruption cause their own dormancy, as cut off from fresh inflowing water the microbes that initiate the reactions in the first place become dormant. Not that any of this applies to commerce which seethes no evil that suiteth not. |

I might have spoken too soon. And the Atlantic pressure charts seem
to show the isobars bringing it further east on Wednesday..... From the BBC news website: Ireland to re-impose flight bans Aviation authorities in the Irish Republic say flights in and out of the country will be banned because of possible risks from volcanic ash. The fresh restrictions will apply from 0600 to 1200 GMT on Tuesday. "Ireland falls within the predicted area of ash concentrations" that exceed acceptable levels, the Irish Aviation Authority (IAA) said on Monday. Flights over Europe were banned for six days last month because of fears of the effect of volcanic ash on jet engines. The IAA said over-flights from the UK and continental Europe would not be affected. |
