The cam at http://live.mila.is/jokulsarlon/ seems to be showing an increase in flooding. Previously you couldnt see the water moving but now it clearly is flowing fast towards the camera.

This is a stunning picture of the eruption: http://www.visir.is/almannavarnir-hafa-mestar-ahyggjur-af-oskufallinu/article/2011110529772

I think this area is tidal - it was flowing the other way last night & a small whirlpool was visible.

Yep the cam is looking Northwards (meaning its located on the South coast of Iceland) however if the inlet is where the main tributary of the Grimsvotn glacier flows into, it could be interesting in a few hours time.

the icebergs seem to be piling up as well.

do we know the location of this 'lake' in relation to grimsvotn? lakes arent generally tidal unless they are connected to the sea. if not then it has to be glacial floodwater

I like it when when volcanic eruptions in northern latitudes are happening in late spring and early summer as they block some sunlight. Also more hours of daylight means more chances to observe the plume.

Does anybody know how long the eruptions of this volcano normally last?

Having watched this cam for weeks (on and off) I think the water must be tidal as I have seen it flowing in both directions. However the flow seems faster than I have seen it previously and it seems to be flowing over some of the ice which I have never seen before. Should be interesting watching for the next few hours to see any increase.

On the Mila cam for Jokulsarlon it is worth right clicking on the picture to see it full screen. The flow definitely seems far more than the usual tidal rate now and also seems to be increasing in the last quarter of an hour.

it must be unusual because cars keep turning up on the webcam and people are getting out to have a look

Looks like the place to watch then as usually there are only a few cars but not such high activity as today. Nice to get a front seat view.

Also I have never seen the ice moving and breaking up like it is, the waters are possibly warmer but certainly the increased flow is relentlessly wearing away the ic e in the foreground. Can't wait for the new cams to come online. I do like the way the Icelanders respond to volcanoes by putting up new cams so quickly.

Plume now visible encroaching Reykjavik. weird to think I was there only in 2002 doing Volcanic field studies myself, and I kept telling myself "next eruption i'll be here"...3 eruptions later...But at least with Eyjafjallajokull the ash-fall came here instead http://nwstatic.co.uk/forum/public/style_emoticons/<#EMO_DIR#>/laugh.gif

i wish there was sound on that i'd love to hear it or is it quiet ,

anymore info on what's going on at the moment

[coldfingers]

The foreground ice on the 'lake' is fast wearing away now in the increasing flow of water on the webcam at Jokulsarlon.

http://live.mila.is/jokulsarlon/

Fascinating too to see the chunks of ice begining to break off further 'upstream' and flow down, further abrading the ice in the foreground. The seagulls also seem to be very interested in the proceedings. Perhaps looking for a meal stirred up by the increasing flow?

Yes, big and interesting changes over the last hour. i wonder if any clever person is doimg a time lapse/? I'm just using my cursor as a measuring device.

WOW! Did you just see the foremost berg just collapse and wash away? Awesome the power of water over ice. Now getting very interesting as large chuncks of ice are coming floating down. Just love it!!! Hubby grumpy at me spending so much time watching this.

Someone has made a timelapse of this area - from Sept 2010: http://spatialanalysis.co.uk/2010/09/02/jokulsarlon-timelapse/

As you can see, it's normally pretty busy there and the flow rates change direction & turbulence depending on tide. Note the wee whirlpool right at the very end - this is what I saw last night.

Thanks for the link to that image LadyPakal, it reaaly does show the immensity of that eruption cloud.

Update 3 says:

CFMU have been adviced by Icelandic met office that there has been a volcanic eruption of volcano Grimsvotn in Iceland at 20110521 1900Z. The plume hight estimated by radar 15-17 km.

ASH CLOUD IS EXPECTED TO REACH NORTH SCOTLAND ON TUEDSDAY 24TH MAY.

IF VOLCANIC EMISSIONS CONTINUE WITH SAME INTENSITY CLOUD MIGHT

REACH WEST FRENCH AIRSPACE AND NORTH SPAIN ON THURSDAY 26TH MAY.

Here we go again panic in the skies

This is one of the comments on the daily mail site: Iceland needs to be held to account for all the disruption to business and travel. If they can't control their volcanoes they shouldn't have them. They should pay for normal power stations to heat their water like we have to. I have to fly to Dublin on Tuesday and will be extremely annoyed if my flight is cancelled again.

Don't know about you, but I quite enjoyed the quiet skies while they lasted. Was sad when the first plane flew over again on the way down to land at the airport - noisy thing.

[Supercell 89]

Wonderful, just in time for my trip to the states .

A chart of inflation of the area shows no deflation as yet - red point is todays. http://hraun.vedur.is/ja/vatnajokulsvoktun/gps_grimsfjall.html Suggests there is still more to come.

Iceland volcano eruption 'likely to be small'

Outdated news it looks the largest or similar to 1875 and looking larger than last years check out iceland dailey news.

It`s massive.

[LadyPakal]

Yes, biggest eruption of this volcano in 100 years and bigger than the Katla eruption in '47. They are saying 10x bigger than the one last year.

Oh, wow. Just found this webcam - guess where I want to be at the moment... http://live.mila.is/lonid/

Rumblings beneath the subglacial Hamarinn & Bardarbunga Caldera's just to the west of Grimsvotn. If magma migration finds its way to fissures beneath either of the calderas, you can be sure a VEI5 event is on the cards.

It looks amazing! I'd rathen go in the winter when there is snow around and I can still swim in the warm water!

Haha, sounds like someone has a rather sardonic sense of humour. Only the British have this wonderful humour I reckon. Spaniards don't understand it that's for sure.
