About the eruption

Hi everyone. I just wanted to upload some info about the eruption. It is not affecting us in any way, unless we where gonna drive the south way to visit our folks or go to the city. We could go the north way but it is not as beautiful as the south way.

No one has died (people or livestock) in the eruption but the most danger are the floods and then how much damages the Ash fall is gonna do for the farmers who live there.

The livestock needs to be inside and the Ash goes everywhere even if people tries to avoid it. The homes needs to be closed too and very, very warm to keep the ash outside. It´s like night all day round where the ash is doing the most damage and it looks like a gray snow storm. The ash is bad in long term, the farmers can´t grow their potatos, grains or grass for the livestock about 1-3 years after the Ash stops falling.

We've had no ash fall what so ever - probably we will not have any. You can see the locations on this map:http://www.icetofire.net/iceland2010Erup

Here are some info from a a leading Scottish vulcanologist who has spent years studying the volcanoes in Iceland. I just took glimpse from there and there in his article.
And, even more ominously, the eruptions of the comparatively small volcano have historically been linked to massive eruptions by the nearby volcano Katla, one of Iceland's two feared "Angry Sisters".
Deposits from the ash cloud formed by Katla when it erupted spectacularly in 1755 can still be found in peat bogs in Shetland and other parts of northern Europe
He explained that the huge plume of volcanic ash which has brought chaos to the skies over Europe had been caused by magma mixing with the ice from a 200-metre thick glacier inside the crater.
"When this volcano erupted a couple of weeks ago, the lava was just coming out of the side and making lava floes," Mr Stevenson said.

"But what is different this time is that the eruptions are in the middle crater of the volcano and the crater there is filled with a glacier which is 200 metres thick.

"That means that when the magma – the hot liquid rock – comes out, it melts the ice and then the meltwater turns to steam. Then that steam expands explosively which then breaks the magma up into the fine ash particles we find in the cloud.

"The lava is also coming out ten times faster than the last eruption."

He explained that there were essentially two possible scenarios facing Eyjafjallajoekull.

"The best case scenario is that the eruptions fizzle out now and the ash clears in a couple of days.

"But in the worst case scenario we could be facing sporadic disruption to flights for a year. The last time this volcano erupted the eruptions lasted from December 1821 until January 1823. And that could happen again."

However, even if the volcano does continue to erupt it does not necessarily mean that air traffic would be as badly affected as in recent days.

The current eruption has produced an unprecedented problem because winds are blowing ash towards Europe and an area of high pressure, and therefore low winds, means the particles are not dissipating quickly.
