@@GeologyHub it would be my contention given the context of your comment that you meant to say "unpredictable" here in your comment, as, it makes less sense otherwise.
While at work today I saw the small volcanic ash warning over the Mexico volcano suddenly become a huge area of warning covering southern Mexico. Did something new happen, or was it a typo that suddenly expanded the ash warning for aviation?
Iceland sure has been lucky with these last 4 eruptions not damaging anything. Not sure how long that uck will last if this is going to keep happening for years. Good live earlier! Lved the drone video. Its funny how different people sound when doing a video versus a live. Could be something to do with the recording software. I've noticed it before with other people though.
Fun fact: salammoniac (mentioned at 3:38) is a very popular candy here in Finland. Goes by the name "salmiakki". I must come to Iceland and lick the rocks there 😅
well... Fire is just hot "incandescent" smoke. So Volcanic gases that glow from heat... pretty much is fire. To further this point... the Flame that comes out of a rocket engine is also heated gases.
Oh it blows big time so does one in Columbia , the Camchattca , and an Indonesia one ,nothing is ever the same no rain will fall as the clouds block sun's heat over all the earth oceans ,little evaporation ,= no rain
A question - given that many of the eruptions which formed the Reykjanes peninsula pre-date human settlement there, is it likely that some of those which are assumed to have come from one large eruption are actually from several smaller ones which overlap, similar to how the Fagradalsfjall lava-fields do? If so, how easy would it be to distinguish one large eruption from a cluster of smaller ones, which stopped and started over a period of a few years or so? I'm asking mainly because it strikes me as curious that so far we've had so many small eruptions in close proximity, when all the recorded eruptions from the last active period created far larger lava-fields, and by quite a considerable margin. While I know it's very early to try and speculate, is this likely to be a sort of "warming up period", or is it possible that we need to recontextualise previous eruptions? And at what point would scientists seriously start to do that?
My thoughts on this as an Earth and Environmental Scientist- especially if its eruptions within several months of each other, its likely from the same magma source and upon erupting, if the previous recent, still cooling lava field is continuing to cool, it could very well remelt with a new flowing of lava atop of of it. However, that is seemingly more unlikely than it is likely. That being said, those eruptions that did predate humans on Iceland, could have been indistinguishable as multiple small eruptions if its from the same magma source as the compositions chemically would still be the same which is why we call them eruptive periods if we cant necessarily distinguish the distinct smalle4 eruptions but know its possible in an area like this. I will say that the patterns of these eruptions that we've witness over the last several years may see scientists in the area to go back out to past lava flows pre-dating human existence in the area to see if there's more indicators microscopically of smaller eruptions grouped together versus one big eruption as previously speculated. One reason I love science, especially Earth Science, is that we never truly know everything and each experience with nature teaches us something new. We have been learning so much about Iceland and its volcanoes in the last few years and its quite fascinating. As scientists, we never claim that we know things 100% because clearly we dont. To an extent, we can only speculate to give any kind of explanation for anything that happens in the universe, but one witnessed and documented experience can change everything we think we knew. There's always something new to be discovered and this experience with Iceland will teach us more with so many scientific eyes able to witness, study, and document these eruptions over the last few years in real time. No one expected the build up to eruption to be so fast just as much as we never expected activity to cease so fast so of course we'll be watching for new building and what happens next.
During the Litli-Hrutar eruption earlier this year some scientists were particularly interested in sampling areas where lava from the last three eruptions overlapped, in hopes of learning how to identify such events in the past - to learn to distinguish one big or continuous eruption from a series of overlapping smaller ones at small intervals.
Remember that it's two tectonic plates pulling apart from each other. Magma displaces surface rock, erupts, then, for a time, the pressure is released.
The pressure builds up and is suddenly released when it breaks a path to the surface. Something like shaking a bottle of pop and opening it. First you get a high fountain, then it just foams over your hand, then stops with some still left fizzing in the bottle.
I remember someone complaining as to why geologist could not supply better information about future eruptions. My answer was to ask them to predict exactly when the neighbors would open their doors and come outside.
Simple answer is, science knows a lot, but not everything. Often people will exaggerate the latter. But lets be thankful Grindavik was evacuated, it could have ended badly.
@@leovanlierop4580 Yes, and the precautionary principal applies when unknown variables place peoples lives at risk. Scientist have hunches, feelings, and their best guesses that sometimes are proved correct, and sometimes are proved wrong. I was a little surprised by the initial unwillingness to at least suggest that Grindavik residents should begin voluntary evacuations of people, especially those with mobility issues, plus livestock, pets, and property, and that anyone not voluntarily evacuating should have firm evacuation plans in place and be ready to evacuate at a moments notice. The fact that residents initially left so many pets and vital property behind points to a lack of preparation.
The dyke has a peculiar recharging mechanism (primary and secondary chambers with an horizontal tunnel in between), so the lava pressure would be linked only to the magma directly below the erupting fissures. I think this is a plausible explanation for why the eruption was so short, like a bottle of champaign.
Good video. What I really hate are the videos going on about it's over, just a matter of time before the area can return to normal (with lethal levels of SO2 potentially in the air, yeah right). And here we see a good chance perhaps the chamber is filling again, it spreads into the dike, and that pressure fissure the earth again, somewhere along it even down into the city. I really think they should simply admit the city is too risky to live in for the near term future. Until Iceland sets this down in writing they will be pressured by locals and population to go home. And we do not want some new event to dump poisonous gases into peoples home and get an almost Bhopal like incident. It's just to risky. Just abandon the city so people can change their lives.
I agree and plus,the newly lava covered area will remain incredibly hot. Large parts of Iceland are not inhabited at all and so giving up Grindavik will be difficult especially with such a nice natural bay there. But possibly they could find another coastal area to rebuild?
Maybe there is not tht much energy underground, or maybe it's just a minor eruption and the major one is by the near future, so the volcano might still be stirring inside. I'm not sure I'm just wild guessing.
Could you please review the uplift data before, during, and after the eruption? Seems like magma displaces a certain amount of surface rock,then stops.
It may take some decades of observation before reliable predictions can be made about eruptions in any of these systems. Gotta be patient and not expect too much too soon.
I think it was said before by GH that Reykjanes doesn't erupt from the same fissure... So with such a long fissure opening along the dike, does this mean that only areas that didn't fissure along the dike are possible new eruptive sites?... Or would a second eruption utilize the existing fissure?... Guess we will find out in 2024!
I think what he meant, is that once the lava in the fissures and dikes have cooled and hardened, the next eruption will not happen at that spot. But if a new eruption happens in as little as a few weeks, the lava will not have had time to harden, and so the dikes and fissures will still be "active".
So maybe this magma intrusion system isn't really done yet. Interesting to hear, since I've seen in reports from residents of Iceland that one of their preeminent volcanologists has advised that short eruptions like this are historically typical for activity on the Rekjanes peninsula. Of course his advice may have changed since that report. I totally depend on you for the best scientific info on these eruptions.
There’s also a possibility that we might be misinterpreting briefly spaced smaller eruptions as a singular larger eruption if people were not around to witness it.
I am no scientist or geologist and therefore, my take on this is a simple one and that the brief volcanic eruption seems to be too good to be true. I am therefore not surprised to hear that potentially that another subsequent eruption is possible. Nevertheless, I sincerely hope that this is the end of it as the people of Grindavík need to have continued hope that they will be able to return to their town sometime in the future. Hopefully, a not too distant future.
Honestly my bet is that this eruption was entirely reliant upon the pressure within the dyke, since the propagation had occurred some time ago there was no continuous inflow. If the eruption had occurred 2 weeks ago I would dare to say it would’ve lasted longer. Another factor could just be the insane initial eruptive rate. I think the original volume estimates were just over 50 million m3. If it has erupted over 30 million that’s fair enough because the lava volume is almost always less than the intrusion estimates anyway.
I'm suspicious about the speed of the eruption stopping... Could it be possible that all that magma just moved, similar to what happened in Kilauea in 2018?
When I saw your live I was struck with the colour blue along with the grays. To know this is sulfur dioxide mentioned in this video helped me understand that I was seeing a blue colour. 👍
If the lift of Svarzengi is due to tectonic forces, a microplate shift, we can expect the lift to move to the East, as happened after the eruptions of Krysuvik and Brennisteinfjoll in 1340/41. I think that the Reykjaness penninsula will quieten down all together, if the shift moves eastwards. Wether this shift moves East, is unsure. I do not have the details of the lavaflows from around 1340. Please make an assessment on basis of lavaflows from that time, as a repeat of that time may materialize.
Idk why, but the experience shows that two eruptions never happen at the same spot for a very long time. So every time it erupts on a remote location, the more likely some infrastructure is affected next time. We've been very lucky 4 times, but it won't last forever. Iceland should be prepared.
The residents of Grindavik are between a rock and hard place. They are being told now they could go back to their homes for Christmas, even though the chance of another eruption is there. But while the government did provide temporary housing, they still have to pay rent, on top of mortgages for the homes they have in Grindavik. And many homes are now not safe due to damage. But insurance money can only be used to repair their homes in the town, where more volcano activity could happen.
When magma vents like this, what replaces it at depth or does it leave a void? Does some reciprocal event occur to maintain the status quo below the crust?
With the history of this system maybe. history of several intrusions of magma that sometimes lead too eruptions then goes quite for 800 years ish. Is this system just repeating history or does it have surprises in a good or bad way?. prepare for the worst and hope for the best. Now all we can really do is watch and wait.
I have a question, since the epicenter of ground uplift from the intrusion of magma is near the geothermal power plant, do you think the geothermal power plant is blocking the path of the intruding magma?
A volcano's explosiveness depends upon the composition of the lava and the amount of gas trapped in it. The basaltic nature of Iceland's volcanism makes it less viscous and the gasses can escape without explosions. It just causes fountaining. That would be different if it was capped by glaciers, because the melting glaciers can cause explosive activity and flooding.
There are several sites on RUclips that cover numerous geology issues. This is merely the one this channel has followed recently because for the last two months there have been several very unusual happenings prior to this eruption finally happening.
Did you know if the geothermal power plant has pipes going deep into the ground to get closer to the heat? If so, is there a chance of magma hitting them and finding the path of least resistance to just blow up the power plant?
Hi I work in geothermal. Most plants have large amounts of pipes only a couple kilometres deep more or less directly under them. In the event an intrusion is detected and there is superheated anything it shuts the pipeline off utterly
@@wazaagbreak-head6039 Interesting. So it'd probably shut down before the magma got too close from it superheating the circulating fluid? What sort of shut off mechanism is there? Still not seeing how that'd inherently stop it if highly pressurized magma capable of breaking solid rock found the pipe and that became a convenient path to release pressure.
Do you knot realize this could very well be a laki like event..you cannot say it won't stop guessing volcanos do as they please stop trying to pacify people it's just geting started
Read a book please.. and laki had pretty much only affect locally, but debating this to prevent loss of life is important. and you have no proof of your claim
Yeah sadly we need evidence. Even small eruptions can do big damage in the wrong place. Nothing say a world changing eruption is on the way at all. No need to scare normies
As someone who has no formal education or training in this area, I can only make an “educated” guess based what (I think) I’ve learned from GHub…that perhaps the amount of gas is low enough (or if not low, is somehow escaping with little resistance from somewhere) and the viscosity is low enough such that the Magma is not getting as much of an extra “push” to cause sustained flows for long periods of time. I’m thinking we will see a repeat of this kind of eruption in January as GHub has predicted. I am curious though, why he thinks it will involve a significant increase in Magma. Looking forward to his “briefing” on that 👍🏼 (throw a coin 🪙 to your geologist 😬)
A significant increase in magma is only a possibility. The region appears to have dodged the proverbial bullet with the magma intrusion threatening an eruption in some many areas over the last couple months. It may take a few years to unravel what is going on here. After all there have been no eruptions in this area in 780 years.
There are glaciers in parts of Iceland mostly on mountains, but mostly it is just very cold and snowy in winter. Much like other countries with territory near the Arctic Circle.
All the weeks of Hype ended with a Very Small Eruption. Now you are Starting the Same old Hype Again. Let it go. Eruptions in Iceland are Nothing New. Try Reporting on something Interesting instead,
What's the matter you want your money back for the time invested in watching and expecting something to happen?? Here is a quote from the book Dune that applies. "Deep in the human unconscious is a pervasive need for a logical universe that makes sense. But the real universe is always one step beyond logic".

@@tHebUm18 The pipe would presumably act as any other crack in the rock, but there's plenty of those.
"... via a view ...", huh?
Do you knot realize this could very well be a laki like event..you cannot say it won't stop guessing volcanos do as they please stop trying to pacify people it's just geting started
Read a book please.. and laki had pretty much only affect locally, but debating this to prevent loss of life is important. and you have no proof of your claim

Why didn’t the fissure extend into the ocean?
Because it found a weak spot elsewhere
The AI voice, no thanks.
This is not AI.
Is the ground dropping around this eruption. If so, is that normal.
WOW I thought Carl Sagan came back!
Given that the area is now covered in cooling lava, im hoping the new magma wont find an easier path to the surface ie the center of Grindavik
me imagining a kid in Arizona holding a rc remote with the largest antennae ever
Thanks serious Goofy
What was the latency like on the drone?
At that distance around 100 ms if you have a good provider at both ends.

Very small eruptions. Odd i think. Im still expecting a bardabunga sized eruption within the next 2 yrs.
so its not over oh no.....
How are you proving this?
@@xwiick just a guess
there is still the large erruption left... something tells me it´s going to go be very big next time.
Yeah sadly we need evidence. Even small eruptions can do big damage in the wrong place. Nothing say a world changing eruption is on the way at all. No need to scare normies
As someone who has no formal education or training in this area, I can only make an “educated” guess based what (I think) I’ve learned from GHub…that perhaps the amount of gas is low enough (or if not low, is somehow escaping with little resistance from somewhere) and the viscosity is low enough such that the Magma is not getting as much of an extra “push” to cause sustained flows for long periods of time. I’m thinking we will see a repeat of this kind of eruption in January as GHub has predicted. I am curious though, why he thinks it will involve a significant increase in Magma. Looking forward to his “briefing” on that 👍🏼 (throw a coin 🪙 to your geologist 😬)
A significant increase in magma is only a possibility. The region appears to have dodged the proverbial bullet with the magma intrusion threatening an eruption in some many areas over the last couple months. It may take a few years to unravel what is going on here. After all there have been no eruptions in this area in 780 years.
A basaltic lava flow in Iceland similar to the Deccan Traps?
No way to small.
Comparing a dinky fissure eruption like this to the Deccan Traps is about like comparing a sneeze to a hurricane! 😊
As a layman I said, this is not over. Perhaps experts do best to comment as things happen instead of trying to predict….
You do know people wanna go home right?
The orc will build tower there.

That’s a week and a half away…
Is this Iceland? I have thought Iceland is ice land.
There are glaciers in parts of Iceland mostly on mountains, but mostly it is just very cold and snowy in winter. Much like other countries with territory near the Arctic Circle.
All the weeks of Hype ended with a Very Small Eruption. Now you are Starting the Same old Hype Again. Let it go. Eruptions in Iceland are Nothing New. Try Reporting on something Interesting instead,
A lot of people do find nature interesting, weird huh?
Do you have to go to school to learn how to talk like an AI bot? - or is that what this is read by?

Wow... We waited for one month or more to have a two-day eruption. Seriously.
What's the matter you want your money back for the time invested in watching and expecting something to happen??
Here is a quote from the book Dune that applies.
"Deep in the human unconscious is a pervasive need for a logical universe that makes sense. But the real universe is always one step beyond logic".
I Imagin there is like a plate of rock above the continental plate that fills under it and after releasing pressure it fills again.
