Iceland's Eyjafjallajokull Volcano

[The PIT]

Funny how we get ash on the cars but the skies are clear. Must be coming up through the ground B) :lol:

Never saw the ground look sparkly before Pit, You made me smile with that bit of sarcasm.:winky:

Volcano seems to be puffing away merrily today with a lot of ash still but fortunately low level. Still winds are in our favour at last.

Lots of melt running off here (the Vodaphone cam): http://extras.vodafone.is/trailers/fimmvorduhals/mx10-4-235-80/2010/04/24/10/current.jpg

and it seems another vent has opened overnight in the caldera.

Those are beutiful

wonder how long this volcano will carry on erupting

[johnholmes]

I will come back with some info on contrails along with references to those parts about contrails that I personally have doubts about. I hope an informative post. Hoping to post over the weekend-time permitting.

my apologies but yet more pc problems to do with my pc means I am unable to load charts via My Pics into the article I hoped to post in here.

If anyone knows of another way of copying charts and pasting them, either into a word document, to be issued as a pdf file, or directly into here I would very much appreciate their help. At the moment I am also unable to prepare any tutorial work for NW nor to add charts to my web site when I do my twice weekly voice over of the forecast for this area.

Hi Snowcheeks

Many thanks for your help but!

John - try a screen shot ? alt and prtSc together. Then ctrl v to paste into word.

I can copy and paste into word-no problem. The problem occurs when I try to make a copy to paste into, either my web site forecast area via my piccs or the same into Net Wx areas?

I tried what you suggested direct into my piccs and it disappeared off the screen immediately as all other attempts have done.

This morning I spent about 1 hour trying a variety of ways suggested by the pc bloke but none worked.

Restart the pc, system restore, into control panel and tick, via system-advanced-performance settings and putting tickes, in the end in all 3 boxes. Previously ticking the IE box had worked for several days. On Thursday morning it worked as I made my new voice over forecast with charts copied in. On Thursday evening trying to do the same for the item about contrails it would not. Nothing had been altered in the meantime. This has been going on off and on for about 2-3 months. Prior to that I never had any problem and with no boxes ticked. Kaspersky found no problems when I used it yesterday. I've defragged recently. So am at a loss to know what the problem is or how to cure it. The techie is coming Tuesday to do a quick check but almost certainly to take it away and run more extensive tests to try and find the problem.

Again thanks for your suggestion-anyone else any ideas. I'm copying this into the 'need help on the site/forum' in case anyone is able to help there.

cheers

This webcam showing that an awful lot of ash is still spewing from thos volcano.

Lets hope the current wind direction is maintained as this isn't a good scenario. No wonder the Icelandic authorities have closed their airports.

Hekla having another tremble.

[coldfingers]

Eyjafjalljokull still lighting up at times on the Hvolsvelli webcam. When you can see through the murk that is!

No wonder there is an increased flow of water off the glacier.

Shame the other two webcams don't seem to be working or not available.

[The PIT]

Can't see anything on the webcam I presume it's still erupting though. Tremor pretty steady but not s high as before.

[coldfingers]

On this webcam the ash seems to have split into two streams, unless (and I suppose this is the most likely) on stream is low cloud.

http://www.mulakot.net/myndavelar.html

I suppose it could be the other vent as well that someone said was now active.

The two different coloured streams are 2 vents - one mostly ash & the other mostly steam. Apparently lava has started to flow sub-glacially which is adding to the melt & the steam.

I flew back from Cuba Friday night/ Saturday Morning and nothing looked different from normal at all, not even the sunset or sunrise. There was no discolouration on or around the aircraft that could be seen and trouble free flight except for over the Bahamas.

Not enough SO2 for the nice colours at sunrise/sunset. The ash cloud was partially made of such fine particulates (the bits that made it to the ground were only the coarsest bits) that it would be pretty much invisible to the naked eye, once the heavier bits had dropped out. The Swedish? jets that discovered their engine damage noticed no ash cloud - said the skies were clear.

Anyway, the winds changed on Friday and blew it all away. Now the Icelandic airports are getting it.

Aye, the last time I was past Glasgow Airport the Icelandair planes were lined up outside.

My HTML coding skills are a bit rusty but. try googling HTML commands for website pasting. E.G... To add a border to a pasted photo you would add, ............ <img src="images/Johnholmespiccy.gif" alt="" height="114" width="266" border="red#01"></td>

Hope this helps

But it was disclosed yesterday that volcanic ash in the skies around Britain never reached more than a fraction of dangerous levels throughout the crisis which followed the eruption of the Icelandic volcano, Eyjafjallajökul.

Scientists who analysed samples of powder collected during the six-day shutdown of British airspace confirmed that concentrations were only ever about one seventh of the new safety limit agreed by the aviation authorities.

It means that the closure of European airspace on safety grounds was unnecessary. The closure of airspace came after the Met Office published projections appearing to show potentially dangerous levels of ash stretching as far as Russia. But it can now be disclosed that they included areas where concentrations were as low as one tenth of what has since been agreed to be dangerous.

One senior official in the Civil Aviation Authority, which regulates Britain’s airspace alongside the air traffic control service, Nats, admitted that the plume of ash had often been “close to undetectable”. Last week government agencies including the CAA agreed that planes should be allowed to fly unless ash concentrations reached a level of 2,000 micrograms per cubic metre of air.

But Prof Stephen Mobbs, director of the National Centre for Atmospheric Science, who was responsible for carrying out test flights, said that the highest levels detected above Britain was around 300 micrograms in "patches". He added that new maps published following the setting of the safe limits showed an unsafe flying zone covering only a “small area around Iceland”. Jim McKenna, the CAA’s head of airworthiness said: “It’s obvious that at the start of this crisis there was a lack of definitive data. It’s also true that for some time the density of ash above the UK was close to undetectable.”

Sir Richard Branson, the Virgin Atlantic boss, said: “This was very much a Government decision to ground the planes and we would suggest that the Government should compensate the industry. "Behind the scenes our engineers and all the experts were telling us that there was no danger at all to flying and that the danger would have been if we had flown close to Iceland through the volcano. "There were plenty of corridors which the airlines could have flown through which would have been quite safe, so I think the Government has accepted that there was overreaction."

A spokeswoman for the Department for Transport said: “Safety is paramount. The decision made by safety regulators to restrict airspace was made in line with long-standing international guidelines and information from aircraft manufacturers that any volcanic ash could pose a danger to aircraft.

"The whole of Europe has been in the same position, acting according to the same aviation safety rules.”

What a shock, the convicted tax-evader Richard Branson is shaping up to demand compensation from the government. Take, take, take. I hope the government tell him to get stuffed. Why should they pay a penny to the airlines?

[SnowBear]

The international guidelines were, no flying in any volume of ash, they stuck to those rules until it was investigated by engineers and authorities and the rule change was made. That's not over-reacting, that's following rules and guidelines. All hell would have let loose if thy had ignored the rules and an accident had occurred. With planes, even if the safest form of travel, utmost safety is needed at all times. With the amount of planes flying in the air at one time, (and once I counted 17, yes 17! aircraft in the air over my visible sky area at the same time) things can go drastically wrong in a very short space of time, if you had say 5 planes fly though a denser ash cloud.. an air traffic control headache in the extreme for sure! Before the tests and investigations there was way too many unknown quantities to take risks.

In my view, lessons have been learnt, rules have been adjusted to a 30 year old set of guidelines to take into account recent technology and measuring systems, a closer look at tolerances done etc.

As always, in today's blame game society, we will no doubt still be hearing about this rubbish in a year's time.

I think your post is a first class summary of the situation Snowbear.

This is the relevant bit out of the Telegraph article

Scientists who analysed samples of powder collected during the six-day shutdown of British airspace confirmed that concentrations were only ever about one seventh of the new safety limit agreed by the aviation authorities.

Prior to the investigations prompted obviously by the huge revenue losses to major airlines and the large number of travellers stranded around the world the International rule was IF volcanic ash was believed to be present then NO FLYING was permitted in that area.

As to who picks up the bill at the end I have no idea whether governments, acting on ICAO advice, will pay airlines. Whatever, it probably means all passengers in future are going to have to pay more to cover airline insurances etc for any similar events.

Airlines and ICAO are used to volcanoes in less sensitive area causing minor air problems, SE Asia and downwind of any Etna eruptions also the north American instances but there has never before been a case where the whole of a continent has been forced to stop flying. Rule changes are certain to follow but not at the expense of any even slight loss of ICAO rules for airline safety, or that is my view at any rate.

That's some pretty high odds of eruption there. Although I suppose it means any size of eruption, not necessarily a biggie?

[LadyPakal]

Indeed. A lot of them aren't particularly violent. Eruption of something is always going on there - they are on a part of spreading ocean plate, after all. Something has to fill the gap!
