Iceland Volcano Updates | Lava flows over a barrier and uplift continues

Hello everybody!
The eruption from the Svartsengi system on the Reykjanes peninsula in Iceland has now been erupting for a cool 44 days.
Activity in the past 3 weeks has been really stable with no signs that the eruption is ending anytime soon.
On April 27th, lava flowed over the barriers northeast of Grindavík. This was to be expected as lava has been building up at these walls for some time now.
Fortunately, this is not much of a problem as this flow is so small with the only concern being possible moss fires which could be a threat to Grindavík.
As most of you know, uplift, and hence magma accumulation, has been ongoing alongside the eruption which has created a lot of uncertainty.
The estimated amount of accumulated magma is now well within the range where intrusions have occurred previously so experts and volcano watchers are expecting something to
happen at any time now.
The largest earthquake in Bárðarbunga since its previous eruption, Holuhraun, back in 2014-15, struck on April 21st, what does it mean?

a factor in blockages is that the magma can gelify if enough gases are released from it. degassing generally leads to formation of minerals that have a higher melting point. also the chemical reactions to form different minerals may absorb or release heat - liquefying or gelifying the magma if the transition temp is close. a lot of complex chemical reactions are occurring that can cause blockages or suddenly release blockages. its a very dynamic situation under the surface. its not just a mass of hot magma hanging around doing nothing.

[@Hliarmenn]

Yeah, I find it fascinating how unpredictable these events are and how fast things change like you say. Thanks for your awesome comment, really informative!

From Michigan, USA I thank you for your informative videos. Geography has interested me since an uncle introduced me to it and I learned that he found the North Slope oil in Alaska. Your easy manner reminds me of him and from you, I have learned much. Thank you again for your interesting information, I look forward to your next video.

Greetings from Arkansas, USA. I always look forward to your updates. I think we will see increased activity in the current cone as the plumbing system is well open, and like water, magma is lazy. It seeks the easiest pathway to the surface. 😂

[@Feralkittykat86]

Stay safe Arkansas. Been following the storm system over there, current system is causing a fair bit of chaos... Though the last F3 was fascinating to see

I am not scientist, just happened to watch this volcano saga from mid november last year and have different feeling about ongoing eruption. It is when I watched the start, there were 2 different volcanoes opening almost at the same time. First, northern fissure was usual volcano from Svartsengi reservoir and died out fast like all previous and second, southern volcano from different source what is still ongoing. When Svartsengi reservoir fills up again, it will trigger next volcano north from existing southern volcano.

[@Hliarmenn]

Definitely an interesting idea. Could well be that this eruption is being fed by a different source than from the chamber that's filling currently. Will be interesting to see that our experts uncover.

[@allenra530]

There will be other breakouts along the flanks of the flow, but they are unlikely to be much of a threat to the town. The real question is where the next fissure will open up. This is what keeps us interested in this eruption.

[@Hliarmenn]

Yeah, this eruption definitely knows how to keep us entertained.

Thankyou for the update, it looks to me like the crater has got a bit bigger ?

[@Hliarmenn]

It's definitely gotten slightly bigger in the past week, possibly close to 40m. I've heard, however, that there was a large collapse recently but I'm not sure as I haven't been able to pay as much attention to the livestreams recently

Fun speculation. Thorbjorn is going to split in half, and the west half is going to roll over into the blue lagoon.

Building up the wall while the lava is flowing over, how can they do that ?

[@Hliarmenn]

These construction workers have gotten comically good at working with lava. They've actually just used freshly cool lava to increase the wall heights. This current flow is so small that it doesn't pose any threat to those experienced workers.

[@deedorothypapineau6920]

It’s nice to find a video from you. I was hoping you would spend a little more time on the breach of the wall at Grindavik. I am not an expert but the other build up west of the current volcano isn’t connected and could pose a lot of problems on the west side of the peninsula. What do you think?

[@Hliarmenn]

The volcano systems to the wests definitely seem to be making them selfs ready. They will go off in the near geological future which could be 50+ years. Could also be sooner. Eruptions there are indeed likely to more of a problem due to their tendency to erupt in the ocean which causes ash fall. That would be a disaster for the international airport.

[@williamlloyd3769]

You have to wonder, now that in some areas the lava flows / pools have filled the areas next to the berms, where the next major eruption / flow will go. Hopefully toward the sea.

[@Hliarmenn]

That's actually true. A new, powerful lava flow would have no problem flowing over the walls now and I think, if it flows so it would be directed over them instead to the ocean. Hopefully our construction workers are able to make them taller or that this possible new fissure opens further north.

[@MikeGreenwood51]

It looks like the defense wall needs to be heightened for the lava to go south to the open ocean. My obsrvations are that at that point where the lava breached across the top of the wall L12 East. The wall actully dips a little there making it a little lower. Or an area of least resistance and so lava would go there.

[@Feralkittykat86]

So the place i affectionately call a lava pond, may either get angry or have company.... The feeding system does sound similar to how usgs described Kilauea's "plumbing", just different positions. Hawaii is on a hot spot and well Iceland isn't... How it's being fed into sounds similar, a open channel from deep down. Don't think the air lines can take another 2010 style shut down since COVID... British airways is still recovering from both 😅

[@andrewhotston983]

Very puzzling - if the uplift is caused by increasing pressure in the magma chamber, why isn't the flow rate in the eruption increasing? Could there be a second magma chamber, completely separate from the one feeding the current eruption, or could the uplift be due to something else - perhaps decreasing density of the crust due to heating?

[@Hliarmenn]

There are so many possible explanations but check all the boxes. Hopefully our experts are working on new models that can explain all this in detail, that is, what's going under the surface.

[@petes5041]

That's what Lava does!

[@zainmudassir2964]

Is is possible to drill so to release some magma pressure?

[@leechild4655]

I wonder if in the uprise of an area there is no magma involved. But once the inflated area breaks the crust and deep cracks form, then the gas that came from the sudden fracture is expelled at such a high force and velocity it ignites and a burning hole delvelops and grows deeper and wider, or as far as the cracks go. Thats my sort of theory I have from watching it all.

[@leechild4655]

what caused the inflation? orogeny.

[@d2sfavs]

thanks for the update.can you tell me how much difference is there between last months eruption from shallower magma and the deeper eruption going on now chemically is there much difference between the two types of lava.

[@ericfielding2540]

Shawn Willsey covered some chemical or geochemical data last week. It seems that the lava from all the eruptions since December are extremely similar.

[@Hliarmenn]

Yeah, that's correct, doesn't seem to be much of a difference, if any, between them. The interesting part is that the chemical composition is also similar to the eruptions from Fagradalsfjall. I think some geoscientists are researching this currently

[@marladillard8721]

Does lava have the same characteristics as water? Is it being forced into the magma chamber or is it seeking that level?

[@Hliarmenn]

It's being pushed from within the earth as the pressure down there is so much greater than above. In most parts of the world, the crust can hold back, but at weaker areas like plate boundaries, it can push through sometimes.

By making the dams they have increased the heat and longevity of the volcano. This will affect Yellowstone Italy etc.

[@sigisoltau6073]

No it won't. Dams have an effect on earthquake fault lines like the San Andreas fault. Volcanoes though? Nope.
