One of the things that'll be interesting in the weeks/months ahead is whether this eruption continues and if it doesn't, if this is part 1 of an ongoing series of events. I think initially some people were thinking this would be a minor event but with the flow rate remaining steady this suggests the dyke is being refilled, which means a longer lasting eruption. 


I think historically eruptions in the Peninsula have been a series of eruptions that collectively last a long time so it's not out of the question this could be the start of a fairly active period that could last decades (or longer!). 


Or it could all fizzle in a few weeks and that's it

I am not sure if they are new vents or bursts of lava pushing through the partially cooled and solidified surface. The pressure build up below the surface would make it look like a new vent and at least some form of “fountaining”.

It was definitely snow covering the lens of the webcam earlier.


The rate at which the lava continues to pour out does suggest the valley will overflow sooner rather than later.  I keep thinking back to the early days when people were walking around where it's now several feet deep.

Clearly tricky to judge scale if it’s the equivalent of a 6-storey building - and growing.

It has been confirmed that a second fissure niw now formed 500m NE of the existing crater)



Edit: In fact there is now a live cam for the new fissure (in fact it is the original camera which has been moved to show the new tissue) https://youtu.be/BA-9QzIcr3c 


The original eruption site is still visible here: http://k100streymi.mbl.is/spila/webcam0 


And an aerial image to show the location of the new vent in relation to the original one:

No, that is out of either of yesterday’s camera views and it has apparently only formed this morning (around 11:30am local time). They are currently evacuating the area as they investigate it further.

Quite surprised another fissure has opened up so close, will be interesting to see what's going on underground. I'd guess another fissure probably means either the vent from the original dyke to the surface has become partially blocked allowing pressure elsewhere that's forced through more cracks to the surface or more magma is pushing in to the dyke and the pressure has led to a similar scenario. Alternatively it could just reflect the cracked nature of the rocks from the initial push and tremors and lava has been naturally pushing through additional cracks. (Or to put it another way, I've no idea what's going on!)


I guess the immediate question is will the new site starve the original of most of its lava or will they both continue?

There was a live broadcast from net the new fissure a short time ago and I did a little screen capture of it as I thought it showed the speed of the “lava river” quite nicely:

Good grief - if we get the go ahead to travel I'll be tempted to book myself on a trip there, DrM! Mind you - it might be turning a bit nippy away from the lava.

Judging by those videos the activity is over a wider area at the moment than the original site. 


There doesn't seem to be a massive reduction in activity at site 1 either, although the lower cone may not have been quite so active (subjective view) there's still plenty of lava flowing out and another largish chunk of the rim on the taller crater has moved/fallen this afternoon.

LiveStream - Volcanic Eruption in Geldingadalir / Meradalir, Iceland - 2 Angles and a Zoom - YouTube


Not a bad stream with various angles of the 2 sites. Hopefully someone will stick something up a little closer to site 2 once that settles down a bit as the up the valley view is nice to see lava extent but a bit rubbish in terms of the eruption itself.

To be fair to them the Icelandic authorities were happy for locals to visit the eruption site when it was deemed to be safe (weather and volcanic gas emission wise) and the new fissure, while not totally unexpected, could not really have been predicted, certainly in terms of exact location.

I’m not 100% sure that I wouldn’t be there if I was local and had not been told to stay away. Me and my SLR and 50 memory cards and batteries! 

This view in the link below should be looking very impressive in a few hours I would guess. The new fissure is to the top right and the old to the top left with the lave river flowing into the valley at the front. Incidentally it appears that the overall combined flow rate has increased since the new fissure opened, suggesting if anything a strengthening of the eruption.

We now have fissure number 3 between the two previous ones.


There is also camera feed available at the following link that shows all three fissure area currently: https://www.mbl.is/frettir/innlent/2021/04/06/baedi_gossvaedin_i_beinu_streymi_a_mbl_is/

We lived on this volcano for some years in the 70s - top right hand corner - and occasionally the house doors would pop open with quakes - very ghost like. Then 3 years ago they had to evacuate the place...

We often used to find leaf casts and other plant material the deposits on the Island and I'd have debates with my students are to whether such rocks were igneous or sedimentary.


One of our former pupils was in charge of the recent evacuation and was kind enough to keep me up to speed - very interesting.

Technology is amazing. I have alredy spent a good many hours watching this all develop from the comfort of my living room! Driving everyone a little potty here, with "come look at this!" my adult children think I am a bit nuts, they're probably not too far from the truth. I've always been fascinated by Mother Natures exttremes, it's just wonderful to now be able to follow along in real time without having to physically put oneself in danger. Although, given the opportunity, I would jump to witness for real :)
