Iceland's Eyjafjallajokull Volcano

[kerensa]

looking at the webcams has it blown again, a huge plume now!!!

[karyo]

Any web cam links? I am looking and can't find any!

Thank you Karensa and The Pit :-)

Yes, the plume is much higher than in the last 24 hours or so!

hi dogs, ive been watching on and off all day, and it has been fairly quiet till about 20mins ago

hope this is not coming to life again

I see a new standard for how much ash in jet engines is safe coming up. That's the largest plume for a while although it looks more like water vapour at the moment though.

yes was thinking the same...Looks like steam

Heathrow this morning.

Heathrow this morning.

Now that made me squirt coffee over my laptop!

[dogs32]

I suppose it doesnt matter now if this volcano erupts proper because the new weather fronts will blow this towards the Artic anyway

like the pic Mondy, it was like this in Glos this afternoon as we seemed to be the USA flight path

Look at this seismic plot. http://www.simnet.is/jonfr500/earthquake/tremoren.htm

increased activity for almost 6 hours now!!!

Hekla webcam. All ok still. Certainly the seismic plot is impressive.

Now, scientists and engineers have agreed a safe threshold - a concentration of ash of 0.002g per cubic metre of air. At or below this concentration, there is no damage to the engine.

Current data suggested that concentrations of ash in UK airspace were around 100 micrograms (or 0.0001g) per cubic metre, explained Dr Grant Allen from the Centre for Atmospheric Science at the University of Manchester.

http://news.bbc.co.uk/1/hi/sci/tech/8634276.stm

Is the distribution of ash even throughout UK airspace then? How do they know that at no point does it go above 0.0001g/m3 - especially as we have ash clouds in the North of Scotland and Manchester? How can it be that flying through 20 cubic metres at 0.0001g concentration causes less damage than flying through 1 m3 at a 0.002g? :lol: :cc_confused:

I know I only got a C in Physics, but I should be grateful if someone could explain...

Currently all HIAL airports north of Inverness will be closed until tomorrow morning (22.04.10) including Wick, Kirkwall, Stornoway and Sumburgh due to a volcanic ash cloud.

Pretty tough on the islanders. Still they have ferries going ok.

I think it was AFT who asked why can't they fly in volcanic ash, but can sand plumes. Here's a fair explanation: http://www.volvoaero.com/volvoaero/global/en-gb/newsmedia/press_releases/actual/Pages/Default.aspx

Need to get BA up there quick mate. BA stands for Balls to ashclouds. Cameras obscured by the weather now sadly.

A different model, not from the Met O

[john w]

Well all seems normal again were it not for the stuff above.

A number of routes go West aloft gloucester. So maybe it just seems more as the skies have been empty for a long time.

Interesting how many positioning flights are occuring looking at the radar too.

As for the volcano, not sure it will spew much more out.

As for Ash...Money Won

[coldfingers]

Seems to be a lot more water flowing down from the glacier so something is happening up there. Shame the clouds are obscuring the top.

Always has...... always will. Cynical? Yes but I have learnt cynical often equates to realistic.

[Costa Del Fal]

Nothing to be seen on the webcams really as cloud is in the way i think.

So annoying all that cloud!!! Just like Britain! Usually anyway, they must be getting our weather and giving us ash in return. :lol:

The seismic charts seem to be having another slow but steady rise. Wonder why it seems to happen around the same time of day, going in cycles perhaps?

The UK Met Office is still detecting an ash cloud in European airspace, so why is it now safe to allow planes to fly?

The Civil Aviation Authority (CAA) has confirmed that the guidelines regarding flying through volcanic ash have been changed, following six days of discussions between aviation engineers and experts to "find a way to tackle this immense challenge, unknown in the UK and Europe in living memory".

A spokeswoman from the CAA told BBC News: "Air manufacturers, both engine and airframe, were asked to look at the scientific evidence from test flights and at the Met Office data, to understand how much volcanic ash in the atmosphere… jet engines could tolerate [without being] damaged."

Now, scientists and engineers have agreed a safe threshold - a concentration of ash of 0.002g per cubic metre of air. At or below this concentration, there is no damage to the engine.

Current data suggested that concentrations of ash in UK airspace were around 100 micrograms (or 0.0001g) per cubic metre, explained Dr Grant Allen from the Centre for Atmospheric Science at the University of Manchester.

"Analysis of those atmospheric measurements is early and still ongoing and being supplemented with new measurements all the time," he said. "Two research aircraft will fly [on Wednesday] to record ash size distributions to assess how near to the new tolerance concentrations actually are, which will also be compared to previous days."

Simple Money. Since ash moves around and doesn't show up on radar or on visual how the hell do they know whether they've gone above the new limit. The good news is wind direction change will remove the danger.

Just caught a brief view of a plume on one of the webcams so the it's still going Seismic activity peaked over night but now on it's way back up.

The moon last night had a good halo round it. Ice crystals or volcanic ash???
