After a certain period of time depending on lava volume and gas content the sulphur dioxide emissions may become significant (and more so than ash).

Edit: recent reports suggest that the ongoing eruption may have intensified.

I'll admit that there's a bit of me curious to experience the effects of a major (distant!) eruption. Not like a 'nuclear winter' disaster movie type thing, but an event that dropped the annual global temp by around 2c.

At the moment the eruption may seeem small but if it intensifies and/or becomes prolonged over a period of months then it could become similar to some of Iceland's notable events. It doesn't need to be a sudden explosion with massive ash cloud to cause climate effects AFAIK. I think a prolonged medium sized fissure rich in sulphu dioxide may do the same thing.


Currently it is rather pretty to look at!


Iceland has a significant amount of technical and seismological equiment in place and Is suspect this eruption will prove a useful research experience even if part of me wants it to become something more.

Keep that going for long enough or at a high level then things could get interesting.

As I mentioned it does not need to have a massive ash cloud to cause effects that may be felt elsewhere. It's not at that level at the moment I think but if the eruptions go on for months, on and off, as is possible in theory then impacts of climate may become an issue. This is all supposition at the moment but it is something to bear in mind of they situation becomes prolonged.

Very interesting thanks for that.


With regards to the impact on climate would the sulphur emissions need to reach areas higher up in the atmosphere?


The Laki eruption in 1783 coincidentally did appear to have a massive impact on circulation with the years 1783-1788 having especially anomalous circulation patterns.


This too was a fissure eruption but was at point 6 on the VEI scale, clearly several orders of magnitude bigger then this one.


Judging by my masters dissertation data the winter of 1783/84 was truly exceptional, can't imagine we will see that....... but it will be interesting to see if any unusual patterns occur this winter if emissions do increase.

Seems to have been a dramatic drop in seismic activity, so perhaps this is coming to an end

It could be the end, it could be an interlude or it could be the prelude to something much more significant. Either way it has been an impressive if not massive eruption (and a veryhotogenic one)

...so far?

Fissure eruption continues and there was another large quake of 5.5 in the Bunga region last night


I get the impression the Icelandic experts are quite concerned but its impossible to predict how this will play out

Rift valley has formed south of the eruption in Holuhraun lava field,


http://www.jonfr.com/volcano/?p=4899.


As Beast said, experts are concerned about what could happen next. There has been an increased in seismic activity; scientists and journalists have been advised to leave the area.


I expect things to get worse with different phases of eruptions (perhaps explosive ones) before things will calm down again, but then I could be wrong!

On the other side of world, Tavurvur (New Britain, PNG) has produced a major eruption. Some nice pics and a video here; https://www.flickr.com/photos/125506007@N06/14935764197/, and, https://www.flickr.com/photos/125506007@N06/with/14935764197.

Activity has definately increased with magma being thrown perhaps hundreds of feet into the air, it's hard to tell the scale of things. Fantastic video from both cams.
