wow on cam 2 at the moment large dust devil over the laver lake and the fissure looks pritty high

3 or more  .. Waveform , patterns and the like  . It has  post-4726-0-93894800-1409947263_thumb.jppost-4726-0-91914300-1409947279_thumb.jp effects that can not be described   post-4726-0-85934000-1409947433_thumb.jp

So if the other fissure is shooting fountains of 100m, what are those?  500M?

 The whole area is heating up and thermals don't behave quite the way we would expect. Maybe.

Jolt...post-4726-0-90476600-1409949793_thumb.jp Now we see extremely long period... Fissure ripple  like on the surface of a lake.

Note Askja is not happy, that could crack rock that is cold... And expose evolved magma that has cooled to fresh runny stuff. 

Mila Bada cam post-4726-0-48743800-1409950286_thumb.jp Looks like something from the Middle ages, burning witches etc... Its OK its all om CCTV we will get them on crime atch. A sharp drop off in the wave pattern just post-4726-0-31076600-1409950641_thumb.jp Means rock has yielded I think. Somewhere nearer Bada than Askja. Might not see the result too quickly.

I know the twighlight/darkness extenuates their appearance but I have to agree that those fountains are looking seriously active at the moment

Its just the glare in the darkness. Nothing is over the magic 200m atm'

 The flow rate is increasing  most probably so it will be hotter, brighter, its darker and we have a clearer view, but it is not doing its thing yet. Give it a few hours and the pressure of the ripples we have just seen in the graphs will have effect.

There now we wait, for the fun.

This time I can say in all honesty it will not just stop and that will be it. It might just stop then .... But not just stop.

If it is not this ripple then it is one soon after, the event will continue for a good while yet. Bada may chime in so might Askja. No short stop and all will be well here, not with long period waves like that(see previous posted brown/green charts.)

Looks spectacular all the same, now trying to imagine what 500m fountains would look like! 

The lava field is also showing nicely now, it's edge looks to be in the vicinity of the white spots that you highlighted earlier today.  Maybe these were the lava front hitting streams or pools of water?  When/if it reaches the main river I fear our viewing from the mila cams will become obscured.

With long period waves in the charts you may get the chance to see, or if conditions like visibility and shock waves on webcams intervene then maybe not. I would imagine we will get the chance to see high fountains but at some stage the water will interact with the fluid(very) magma and explode ruining the view, and no doubt "cable guy" will not be allowed endanger his/her life in a white vanman mission to clean the lens of Mila  Bada 1+2.

Shame cos the view is a peach.

 

The lava is slow at the moment in Iceland terms for such fluid liquid, given back pressure it will brighten and over top hardened faces of previous advancement. Hopefully we will get the chance to see.

 

There are that many people recording every frame of the webcams we will at least get to see the lead up and initial glacial/lava interaction  :gathering:

Just remembered a fantastic video JP posted

 

https://forum.netweather.tv/topic/62309-general-volcanic-activity-thread/page-90#entry2853352

 

Apparently these were several hundred meters high so a repeat of that all the way along a fissure will be a sight indeed.

 

Wrt to the increased conductivity downstream - could this be solely down to the high SO2 emissions from the fissure eruption?

Great video. Thats it when it gets like that, As near as is possible, I suspect it will be getting into the glacier, soon as it does we loose vis near by, like the Bada 1+2 cams... Just have to look for distant conflagrations like Grims 2011. The ground water is flowing right down to the inner plumbings of the volcanic system, water exists in magma at 1200C without boiling, because of pressure, like a pressure cooker, the water gives clues to the volcanoes intentions , EG conductivity. :hi:It escapes all the time without eruption. Groundwater, springs, the water table etc, quite often the streams flowing from large volcanoes are like taking its pulse.

The big quakes overnight have not been officially checked/released yet, so they only show as tiddlers at the moment.

Mila Bada 1+2 look good but a bit wavy this morning.

That lava field is big, it is giving off some heat so don't expect the sharpest of views through the heat haze. (expect there is a really long and unpronounceable Icelandic word for it) :hi:

Where do you see the m5 quake on that plot Rusty? 

 

Magic pic of the glacier rifting on previous post. That is surreal, like one of those effects you apply to a picture on your phone / photoshop.

About 05;40 Iceland time, sorry I should not have said overnight, its just that I was half asleep :fool:

It is down as this on the main site:-

Looks like the tremor activity north of Askja is dying down now and the activity getting concentrated further south. Going to be interesting too see if any activity breaks through the Glacier.

It is surly going to be in the sight line of the Mila cams, but will the weather play ball? :doh:

Here is a link to an Italian video report from near the fissure, there are other goodies on the page too. :hi:

 

Nothing fresh showing NE Askja post-4726-0-13238300-1410004136_thumb.jp I think you are right Pit.

 

All the activity could just stop at any time, then start again without much warning. I suspect if the fissure stops there will be a heightened danger of Bada erupting or suffering some sort of flank movement, likely in the NE area lining up with the EQ swarm route to the fissure. Whether or not this outcome would lead to a full on VE 6 or just a small one , who knows...

 

  

Big jolt Mag 4+ maybe 5 Bada just post-4726-0-94620000-1410005854_thumb.jp  It may not be right at Bada but near by.

No signs of #eruption or geothermal activity in #Bardarbunga caldera itself.


 



Scientists believe deflation of #Bardarbunga caldera is due to magma moving towards NE along chamber towards #Holuhraun


 


So maybe we will see an uptick in activity later on.

#Bardarbunga cauldron has now lowered 15m due to caldera bottom deflation. Largest ever deflation measured in Iceland.

 

Latest from Twitter

 

That is something quite significant regarding the chances of Bada erupting now Shell.

 

Here is a fresh video of Grimsvotn Badas next door neighbor doing a VE 4 in 2011, the video is as the eruption is dying down  would you believe...http://vimeo.com/104033763 Sorry about the music lol
