General Volcanic Activity Thread!

I think PIT refers to the latest eruption not having a major effect on the UK.

There is no denying the 2010 impacts.

[The PIT]

Pretty fountains still onging ground deformation has levelled off so outflow matches inflow

[IslaArklayblend]

 matty40s Much appreciate your helpful clarification, many thanks!

  Saves me having to point out that both pictures referred to the 2010 event.  I thought the title of the post was clear enough.  

We have a canal here, by the way, but I expect you will know that?  LUCS Linlithgow Union Canal Society.

First possible hints of a return to uplift too early to be sure and will take a day or so to confirm.

[Northwest NI]

Some reports in Iceland of streams drying up around Hekla. Locals say it’s a sure sign of an eruption.

[The PIT]

Helka is a strange volcano and gives very short notice of an eruption. For example in 1980 it gave only 23 minutes notice. Wells and springs drying can be signs of an eruption. There has been some slight inflation there over recent weeks. 

[GreyCrag]

It's not looking promising with activity significantly dwindling away since this early morning, looking at how rapidly things changed the 2 likelyhoods are either the conduit is blocked by now-partial melt or uplift is significant enough to nullify the output pressure. If the situation is the same or gets worse by tomorrow then i'll be cancelling the plans to head there and hoping any future eruption #10 happens within a decent flight window to get there.

I have always wanted to witness Yellowstone erupting in it’s full glory but unfortunately it won’t be for a long time and as it stands; humanity couldn’t survive it in their current 0.7 civilisation state 

 

But still, i’d like to see it, like in 2012 “the film” that was one of my favourite films to watch pre 2020 chaos 

[Ross90]

America might not survive it but I doubt humanity would go extinct because of it.

That was one of the rare scenes in a disaster film where they actually underplayed the scale of it.

[GreyCrag]

It looks like the Iceland eruption is still chugging along albeit currently at 10m3/s down from 15m3/s as it begins entering the phase where pressure equilibrium is keeping the vent open for as-long as the conduit maintains fluidity although it could still cease activity with only a matter of day/s warning. The main obstacle for viewing is the weather but i'm still going to chance it anyway and head out as i've got a South Coast Tour booked for the weekend, it'll be a eventful few days with a (hopefully) erupting volcano, glacier walk, black sands photoshoot, and waterfalls.

[GreyCrag]

Isak is up with the drone in collab with Shawn Willsey with the eruption looking quite good at a stable output.

Bardarbunga had a M 4.97 at 1.7 km depth recently...

There's stupidity and then there's Darwin Award contenders. This prize prat would have had to cross a active lava-field over a thin crust, avoided toxic accumulations of SO2/CO2, scrambled over still-cooling volcanic ejecta, and then decided it was a good idea to stand only a few tens of meters away from a (still unpredictable) erupting vent. All whilst wearing trainers and a man-purse.

DON'T be this guy.

Looks like the activity is just about over but it's built a decent size cone despite the short eruption length. Uplift has now resumed as before so we are now in the next eruption phase. Probably Dec or Jan before the next eruption and it takes more pressure each time to bring the eruption to the surface so it may not be able to break out next time. Time will tell.

[GreyCrag]

Just my luck the eruption official ended the day after I arrived on Thursday  a good job the first thing I did was to head to Grindavikurafleggjari for the closest vantage-point with the best views, there was some crater-venting and a still active lava-field which occasionally had very diffuse magma under parts of the thinner crust. Aside from a brief glimpse of the lava-breakouts ahead of the flow seen late on Saturday night it was a bit gutwrenching to see what 'could have been' knowing that the eruption was still active just 48hrs beforehand.

I still got a great tour of the South Coast on Friday, which included all the sights of Skogafoss + Seljandsfoss waterfalls, Solheimajokull Glacier, Reynisjara Beach, Dyrholaey, and town of Vik.

[The PIT]

Well uplift well truly back on the agenda. A swarm round Krýsuvík which probably the rocks reacting to stress. There's no real land rise at the system so unlikely to be reactivating at the moment.

[Allseasons-Si]

 The PIT There is a Geothermal plant there and the Eq's are probabley due to waite water injection.

[The PIT]

Kilauea has also been erupting weakly at the top of the east rift zone.

The USGS Hawaiian Volcano Observatory issues Volcano Updates for Kīlauea as activity warrants.

Meanwhile uplift continues at Iceland and looks like the refill is stronger than the last pre eruption swelling

Thanks for that, Matty -- say it again! 

[The PIT]

Well it's getting time to watch Iceland again I would suggest a possible dyke or new eruption four to six weeks away. Worth keeping an eye on the quakes.

 The PIT nice xmas surprise
