Iceland volcano erupts on Reykjanes peninsula

The eruption, in south-west Iceland, led to half the sky being "lit up in red", an eyewitness says.

The IMO seem to think that the 18 Dec 2023 eruption has ceased for the moment.

However, the uplift under Svartsengi is still happening, and there is also 'quake activity.

The current expectation is that the uplift will continue, probably there will be another dyke / sill intrusive event and maybe another eruption from around the same area as on 18th December.

tl:dr - probably not all over, yet.

Cheers!

The quake occurred hundreds of miles away from us. But it was powerful enough that we felt it.
 
The nearest nuclear power station to the current Japan quakes was already offline with possible decommissioning in its future due to the presence of fault lines under the reactors! Quibbling had been going on as to whether they counted as active fault lines or not! An earthquake death recently reported on the news today was due to a building collapsing in the town that shares its name with this nuclear plant, Shika.

The second nearest nuclear power station is the world biggest, but is still offline after the events of 2011 brought the sector to a halt in 2012. TEPCO own that one and have been desperate to restart it, but a few years ago got slapped with a fresh ban for safety violations, a ban that just got removed about 5 days ago. Other hurdles including getting local approval for a restart remain.

Regarding the Shika nuclear plant and that earthquake, I was thoroughly unsurprised to subsequently see this:

Last week's powerful earthquake in central Japan inflicted stress on parts of a local nuclear power plant that exceeded the limit anticipated in the facility's design, according to a report shared in a safety panel meeting on Wednesday.

The magnitude-7.6 quake hit the power plant as the authority, a government affiliate, was screening proposed safety measures toward reactivating one of its two reactors operated by Hokuriku Electric Power Co. Both were offline when the quake occurred on New Year's Day.

Yes, Grimsvotn area had a decent 'quake this morning ...

[no headline article on the IMO, though]

However, the Grindavik hazard area is still active, with continued uplift under Svartsengi ... the IMO seem to think the magma levels are back to about the same as they were before the Dec 2023 eruption ... still wait & see. Personally, I expect another fissure eruption "soon" ...

Indeed. An unlucky worker fell into a fissure yesterday too and is still missing, heres the latest update I saw about that: Bridge put into the fissure: The water at the bottom might be 13 m deep
 
New eruption began this morning. Very close to Grindavík.

You can see how close the new volcanic eruption is to the town of Grindavík in this sobering photo taken from an Icelandic Coast Guard helicopter. Very bad situation unfolding.

The first home on camera is now being affected by it. At time of writing a window or door or something fell from the home and there is some signs of smoke coming from it.

 
Yeah, it looks like a secondary fissure opened even closer to town.

Hope the people whose home that is have got out everything possible.
Must be devastating ...
 
One of the stills on the BBC live page shows diggers constructing a new [?] bund, with houses close behind ...

Although the existing bund in the map just above does seem to show the lava has been diverted. However, they are going to need a new road to Svertsengi !
 
The berm has been partially overtopped/breached right at the point where the main road is. The road is now burning on the other side as a result.
 
The house I mentioned earlier is now properly on fire.

edit - another property has since gone up in flames in the same part of the outskirts of town.

The second fissure opened at 12:10 and the IMO think that the dyke has continued to propagate under Grindavik itself.
It looks as if the lava could end up in the harbour ?

Not sure where the partially diverted larger flow [from the initial fissure] is going to end up, currently heading more or less to the west ...

Some of that might be radiant heat rather than contact with the actual lava.

Yeah the bern or whatever we should call it has done a pretty good job so far, its redirected a hell of a lot of lava and it looks like the breach at the road didnt persist in quantity. Shame that stuff opened up beyond the bern.

And yeah they've knows since the initial event months ago that some parts of the system stretch under the town, so the risk has always been there. They've got various bits of evidence that can point towards magma reaching these near-surface systems, and whether more magma is still entering the system as a whole, but actually predicting whether any of that will reach the surface within town is not easy. I think the signs so far are that its a realistic possibility, but its still a watch and wait game.

Now that darkness is falling we can see the flashing lights of response vehicles, eg on the road either side of the bern. Have to be a bit careful with interpreting some of them though as could mistake small blobs of surface fire with those lights in places.
