Iceland's Eyjafjallajokull Volcano - Discussion Thread

The board will not allow me to post the live animated gif above direct from the Norway Meteorology Institute, but it certainly looks as if the UK could have some airport closures.

Yes - breaking news now. DfT saying airspace closures Sunday - Tuesday including SE England.

Shuggee you beat me to it! http://news.bbc.co.u.../uk/8684540.stm

The bottom one is going to use up all the black ink very quickly (well you know what I mean). Does this mean that Hekla might erupt?

No I very much doubt it. apparently this helicorder picks up tremors from Eyjafjallajokul so that should be what it is recording unless of course it is strong wind signals which are a possibility. Don't know though if the wind is that strong where it is sited or not.Checking it again it seems to be unusual signals so could pssibly be wind, if not something very unusual is happening I would have thought.

Does ask the question what happened with yesterdays ash cloud.

Helka doesn't give prolonged warnings of an eruption. Apart from that the Helicorder as Coldfingers says isn't monitoring that volcano. I suspect that is wind it's picking up as the other recorders aren't going nuts.

I suspect airlines will keep going until there's a crash.

Reading between the lines on the bbc news page I posted the link to it does look like the new gov is going to be keeping an eye on things ash wise. Someone certainly needs to as I don't have any faith in business to be ethical I am afraid.

It is wind - there is a link at the bottom of the helicorder page that show the wind speed in the area of the recorder & the guy who set it up has said it is wind noise.

Thanks for the confirmation LadyP.

That ash column is looking really huge and strong now, the wind doesn't even seem to be bending it and looking at all the dust being kicked up on the Mulakot cam it is pretty windy there too. Tremors low on the esk chart though so not sure if that means the lava isn't flowing as stongly.

Pretty much my favourite cam at the moment showing all the ash around. No light aircraft there today me thinks unless it belongs to KLM or BA.

[West Sussex Kate]

how long does the wind look set to be coming from this direction ?

Oooooh cheeky! Wish I could take a parachute when I fly in June. Not flying with BA though so may be OK, even going to miss the strike action.

There u go from 2mor uk airports could shut until tuesday

Ah, so the mention of Hekla in brackets below the heading of the second chart is just to confuse numpties like me? :lol:

Sounds like BA aren't very happy they may be forced to stop flights.

Quote. :-

A spokesman for British Airways said meetings are being held with Nats to work out the likely impact of the ash.

He said: "There is a possibility of some disruption of airspace but we can't give any firm details yet.

"The public will understand if there are some disruptions. It is out of our hands.

"I don't want to jump to any conclusions - we don't know if it will even extend this far yet."

we do not have any planes

Latest vaac showing the BA avoiding ash cloud prediction.

Translated this means we will tell nats the correct procedures and safety values. There is no ash up there just some people smoking cigs near our engines when they're parked up.

Something keeps falling down, every so often, in front of that split rock - hot water maybe. The whole runoff fan looks quite warm today and steam is rising from it in places, off and on.

Could be dust being blown about I suppose...?

In just under 4 weeks I'm off on an expedition to a remote North Atlantic island which involves flying into Stornoway. Nine months in the planning. Damn ash cloud better disappear by then.

Isn't that when there's the FI Northerly???

Don't worry they'll be new guidelines by then.

The new ash clouds from the met office. I prefer the vaacs what do you think. http://www.metoffice.gov.uk/corporate/pressoffice/2010/volcano/ashconcentration/index.html

Sure doesn't look like dust. Small white plumes every now and then. Even one rolling down just a minute ago, so I gues there is a bombardment going on.

[BARRY]

It's really chucking the ash out now.

[coldfingers]

Interesting that the tremor rate has dropped to the lowest rate since the eruption began, yet she still seems to have no problem blowing her top.

Tremor looks to be the same as when the eruption began. Still the vent won't be blocked so the magma doesn't have to push it's way through.

Assessment - 15 May 2010 17:25

The eruption plume is gray and the height is mainly ~ 6 - 7 km / 21,000 - 24,000 ft, occasionally reaching 8 km / 27,000 ft. It is heading southwest and later south.

Ashfall has been reported south of Eyjafjallajökull and ashdrift southeast of Eyjafjallajökull.

An earthquake swarm started beneath Eyjafjallajökull just before midnight. In the period between 23:54 and 02:45, more than thirty earthquakes were located at depth greater than 20 km and magnitude less than Ml 2. A few more earthquakes were detected until morning.

No major changes are seen in the activity, the ash cloud is slightly higher than yesterday. Presently there are no indications that the eruption is about to end.

Details in status report issued collectively by the Icelandic Meteorological Office and the Institute of Earth Sciences at 15:00.

Not sure if that is ash falling or dust blowing on the Mulakot cam but visibility is poor at the moment.

Heat in the plume on the thermal cam seems to be increasing but I suppose it could always be thinner cloud allowing the heat through.

Tremor on the charts struggling to rise from a deep trough.

Wow. Those don't look like clouds on the AXIS cam. I'm pretty sure that's one big pile of steam. It's not going any direction. Just hanging around the ashplume.
