General Volcanic Activity Thread!

Top of the plume is now at jetliner height. Latest info from VAAC is 15km! There has been reports of lightning but we may need to wait for dark to see it via this webcam.

Here's a pic taken from the north; http://twitpic.com/50qrox

Watch this and pay attention from around 21:00 - Iceland is pretty much clear of cloud at that time. It's pretty neat. http://www.yr.no/satellitt/europa_animasjon.html

good blog for keeping updated on iceland

the horizon has completely disappeared on the webcam now

The sun also goes down 11.52UT in iceland, rising in 5 hours time again so a combination of factors leading to complete darkness over there right now. Over in Reykjavik it will still be twilight and nothing compared to this, at least for another hour while the sun hovers above the horizon. Goes to show the difference in ash density and what less than a hundred miles can do.

Is this one under a glacier as well, implying flight chaos like last year? Anyway, does the ash cloud still pose an airline threat?

[LadyPakal]

The only reason we got flight chaos last year was due to wind direction - flights over Iceland are being diverted around but we don't have the blocking systems we had (hence winds blowing from the N & NW) like last year so no ash likely to go over us (unless the winds change).

Yes, it is sub-glacial so flooding is expected from melt waters in the next 10-12 hours or so.

Katla cam still in relative sunlight (its sunset though so you'll have to be quick)

Plenty of Lightning action going on: http://andvari.vedur.../vikan_is.html?

EDIT: Hmmm for some reason the whole map has been cleared of previous lightning. There was lots in Iceland before the map was "refreshed" of all lightning!

Video too:

Mmm, something interesting on the Internet, excellent. Just been gardening all day friends round, then relax, TV....Eeek.. Volcano

Try this link http://cimss.ssec.wisc.edu/goes/blog/ nice sat footage.

No doubt there will be an enormous glacial melt water flood. Jollaquap (something like that).

The stills I have seen look impressive, 9 miles high I hear.

[LadyPakal]

Latest reports - up to 20km high now & bigger than the 2004 eruption.

[ZONE 51]

Latest reports - up to 20km high now & bigger than the 2004 eruption.

thats incredible! hows this compare to the recent eruption that affected our airspace?

quote.."According to news on Rúv the ash plume from Grímsfjall volcano is most likely the highest since Hekla volcano eruption in the year 1947."

that is a concern, but they are saying heavy ash this one, this must mean it would drop quicker i would imagine

Im on a flight from the USA in 2 hrs hope this dosen't effect me

Iceland volcano eruption 'likely to be small'

[toggerob]

Typical misreporting by the BBC, where the hell do they get their 'journalists' from? even last night the Icelandic authorities were verifying the eruption column was bigger than that of the 1947 Hekla eruption which was VEI4 on the category scale. For comparison the past Grimsvotn eruption in 2004 was VEI3 while Eyjafjallajokull last year measured VEI2.

The typical BBC only want to cover a good story if it involves 'doom and gloom' or the misery of millions of travellers, nevermind the fact a spectacular natural event is happening across the waters 'next door' to us. It just goes to show how corrupt this 'organisation' has become, and I joined in boycotting its agenda a long time ago.

And in all eventuality until the Ash silica has been tested & verified to meet VAAC regulations, its still up for debate just what aviation code will be given out until all checks have been completed on the ash composition. There's much more to it now after Eyjafjallajokull than looking out the window to see if the skies are clear.

I know Eyjafjallajokull was a pain for travelers, but it was amazing to look outside and see a 'proper' summer sky, not one contrail, not one cloud. It was a very interesting event for me.

Interesting furthermore was that Eyjafjallajokull formed 2 new hills!

[Rustynailer]

And the first airport to close is :- http://www.icelandreview.com/icelandreview/daily_news/?cat_id=29314&ew_0_a_id=378077

Stand by for an interesting volcanic episode on the Internet.

The ash is heavier so it won't go as far.

There should be a glacial flood soon, if it is filmed it will look cool IMO.

Take care everybody, volcanoes about...

http://live.mila.is/jokulsarlon/ Flood I think, not sure but I think it started ages ago... It could be normal activity at this cam though, as I am not familar with it.

Grímsvötn largest eruption in 100 years http://www.ruv.is/frett/staersta-gos-i-grimsvotnum-i-100-ar

Look forward to some interesting satellite photos.

we'll know soon enough if the ash will affect air travel, quote from iceland met office-

" At 21:00 UTC, the eruption plume had risen to an altitude of over 65,000 ft (~20 km). Initially, the plume is expected to drift to the east and subsequently to the north. Thus, the ash is not expected to impact aviation in Europe, at least not during the first 24 hours.

by tomorrow, the weather patterns give us an airflow from iceland, over the n atlantic, then to the uk, so we will see...

[The PIT]

Yes interesting the wind shift. I guess the wind strength and height will also have an effect on how far the ash travels. However no doubt British Airways will announce the ash is safe whatever happens.

Web cams still not working.

Look at the tremor here http://en.vedur.is/about-imo/news/2011/nr/2174

[Rustynailer]

Web cams still not working.

Somebody said of the Lake cam "Just 3 hours ago, the ice bergs at Jökulsárlón were pristine white" So I think the ash on the icebergs is fresh. Sort of indirect cam http://nwstatic.co.uk/forum/public/style_emoticons/<#EMO_DIR#>/cool.gif

Yes they were very white. I was wondering if they would be black this morning and they are.

Can you see all the camper vans in this webcam - I hadn't realised how big those bergs were - the image was deceptive until I saw some traffic last night - I thought the 'river' was not so big. Ash fall has now reached the Katla cams it seems.

You can see the wind change on this - eruption was about 21:00: http://www.yr.no/satellitt/europa_animasjon.html

The floods are called joküllhlaups, btw.

3 new webcams coming here: http://live.mila.is/grimsvotn/ - Eldgos i Grímsvötnum 1+2 and Hvannadalshnjúkur - they aren't working yet though.

Video taken from plane here:

- towards the end you can see some lightning.
