Hello everybody!
The eruption that began on February 8th in Iceland on the Reykjanes peninsula is over meaning it lasted just over 24 hours making it one of, if not the shortest, effusive eruptions, we have on record in Iceland.
Despite looking promising in the beginning, this eruption turned into a nightmare quickly when one lava flow was directed in an unfortunate direction which lead it towards a hot water pipe that over 30.000 people depended on.
If you want to hear more details regarding this situation, check out Just Icelandic's video if you haven't already: • Not Just a Natural Dis...
We've now gotten enough GPS data points to see clearly that uplift continues meaning there's still magma flowing into the chamber under Svartsengi.
A really interesting study conducted by an international group of scientists, the University of Iceland, and respected Icelandic geologists has been published revealing some intriguing insights into the Nov. 10th intrusion event and shows just how big that event truly was. More on that later.

You should emphasise that no hot water means no heating otherwise everyone outside Iceland is wondering what the problem is with no hot water - surely they can go without a hot shower for a few days ?
Exactly, I thought it wasn't a big deal. Surely they can heat the water on a stove right??
Yeah, good point, definitely since it's cold here now. I have relatives who live in Njarðvík which are relying on electric radiators and gas heaters. Such an unfortunate turn of events. Hopefully, everything goes well.
I think they use the hot water also for heating their homes, therefore, no heat inside the house.
@@dbrownthompsonYeah, the hot water is used for heating which is why everyone had to buy and use electric radiators.
This increases in electricity usage also resulted in a problem as it was overloading the electrical grid which means people are having to be conservative with electricity too.
yeah it is a little different there than most other parts of the world. Russians would get it. They use thermal power stations for hot water heat too. Its just not a common thing so most people definitely wouldn't understand. It has its obvious down falls.
Thank you yet again for an interesting and informative segment! Our hearts go out to the thousands of people having to cope with freezing homes and the threat of water damage to their properties! An awful situation!
Thank you for your updates!
You're welcome, thanks for tuning in!
In addition to the shorter intervals between eruptions and greater uplift, it seems that there is a shortening of the time between indicators showing an eruption is imminent and the eruption occurring. That's pretty scary since a future one could occur without any notice!
Yeah, that is true. As these intrusions release all the pressure there won't be much of an indicator left for future eruptions. Like the precursor to this eruption, which was just 30 minutes.
Thank you for the update. Praying for everyone in Iceland. What a terrible situation, and it doesn’t appear to be over.
Thank you. You did a good job of describing these eruptions in "layman's terms" for those non-scientists among us who are interested but not geophysics majors. :) I enjoy your content!
Ayy, that's awesome to hear. Thanks for tuning in 😁
Thank you for the information and keeping us posted.
You're welcome!
Thank you for the update. Glad that residents hadn’t moved back in to Grindavik. But it has to be hard to neither have your home, or loosing heat and not knowing what will happen…. Anyway thank you for letting us know!!
Thanks for the great summary of the geology and geophysics paper that was published last week. That November dike intrusion was very impressive, but I did not realize the extreme magma flow rate until I saw the paper. It is sad that the dike tore apart Grindavik and started this new set of lava flows at the surface that has now left 10% of Iceland residents without heating.
Thank you for showing the latest GPS data - they clearly indicate that the current cycle of filling and emptying of the magma sill under Svartsengi isn't likely to end anytime soon. I am also grateful for your concise summary of the paper on the Nov 10 event, which is rather heavy going.
Oh! Already done? And all this pressure released only partially, in an unusually short period of time. I’m no volcanologist but isn’t it possible that these pressures could be released more frequently than 27 days? Like accelerating? How does the scanning of the area progress? Can we get some more knowledge after all the information is analysed?
It actually looks like the rate of eruptions is accelerating which is pretty scary but we can only wait and see if that is really the case.
There is definitely a lot more knowledge and research on the way which will be exciting to learn about. I'll of course keep you updated!😁
@@Hliarmenn The GPS measurement definitely show a higher rate of uplift than previously. But maybe that is due to the short but powerful eruption (quick emptying of the magma chamber(s), demanding a higher magma influx to compensate). Next week we will know more. Either uplift slows down or the next eruption will indeed take only like one or two weeks.
The Icelandic Met Office states 15 million cubic metres between 6:02AM and 1:00PM correlating to an average outflow rate of 600m3/s. It is in fact bigger than the Dec 18th eruption
Those numbers were over estimates with more recent estimates putting it at 10 mil. The 15 mil was also a bit surprising as this eruption did not look as big as the one on Dec 18th.
It takes time to get the data to make the best estimate.
So sorry for your country....may God Bless you. 💜
I was in Iceland last year at this time. So wish I could have seen the volcano. Thinking of the lovely people of Iceland and their safety.
I really hope the pipeline will get better protection now because it is still at risk from another lava flow coming downhill.
Currently, a new pipe is being laid on top of the brand-new lava field😬
They just dumped gravel over the field and paved a thick road.
Since it's not out of the question that lava flows this path again I really hope they do some fortification to prevent another rupture.
@@Hliarmenn That would be wise.
I did another lava flow simulation and the danger that the lava flows that direction again is pretty high should it erupt somewhere between Hagafell and Stora-Skogafell. There is another channel on the northern flanks of Sylingafell, which is a highly probable path.
With lava building up on the eastern side, it could just be a question of time, before any flow is directed towards the western slope.
@@Vulcano7965 Do you program the simulations your self, sounds really cool!
@@HliarmennApparently, the authorities are not concerned about the potential effects of the lava flow's residual heat, outgassing, or settling on the new pipeline.
@@timhazeltine3256nope, I find it really strange how they're just building it on top of s fresh lava field, must be some reason though.
"Like it was its mission..." (2:40) Lol... Exactly what I thought while watching it live. I love your humor in this shitty and chalenging times! Same goes for Gylfi (Just Icelandic)...
Wish you all the best in Iceland, what ever that could mean...!
Gotta squeeze in the humor somewhere 😁
Thanks for tuning in!
Well done! ... ;-))) And I'm always tuned in on your channel...@@Hliarmenn
Thank you, I appreciate the information and the visual presentation
Great job but so scary for the peninsula because there is no way to know what the future holds. I guess Iceland could deal with repeated events in that area but the powerplant is the problem. Retaining walls and rebuilding pipelines are bandaid solutions
In fact the powerplant is threatened by the same phenomenon that makes it a productive powerplant, a large subterranean heat source. I think the Icelanders will become very good at af hoc protective measures.
@ournewhampshirelife. The berm and repairing the pipeline may seem like bandaid solutions, but there is a distinction between the two. The berm has twice proven effective in diverting the lava flow. Though actually this last time the lava flowed just north of the wall around the power plant as it followed a ravine or depression. The berm is the best solution for diverting and slowing the lava flow.
As for the water pipe being damaged repairing the pipe in the short term is the best option at this time. Another long term solution will likely be necessary because these eruptions are likely to continue. This is an unusual volcano experience even for Iceland so give them a chance to figure out how best to cope.
If you have any better suggestions I'm sure that it can't hurt to mention it.
My question: people knew this was likely to continue, and likely to erupt near and endanger the infrastructure. so, has ANYTHING been done to create a back up for residents so they can continue to heat their homes?
Yeah, the preparation is questionable and it definitely looks like more could've been done to prevent disasters like this. There were old hot-water tanks in Keflavík but they were only able to hold amounts to sustain the population for 12 hours. That would've been enough, as there was a spare pipe ready, buried 2 m under the ground where the lava flowed, but it unfortunately didn't make it which created the situation we're in now.
Keep in mind the geothermal power plant / utility hot water loop went on line in 1970s. Fifty years of cheap, carbon free power is a good track record. The last sustained eruptions on the peninsula was hundreds of years ago so not sure if 50 years ago it was high enough risk to spend the money to mitigate. Iceland has a really small population to recover costs from.
PS - I served at the NATO base and the hot water system was great! Betting they get it back on line within two weeks which is pretty good response
@@williamlloyd3769 People seem to forget that the entire country of Iceland has about the resources and population of a moderate sized European _city._
Any discussion of causes should begin with tectonism. Svartsengi is placed on the plate boundary axis. These two plates are being torn apart at the rate of 2cm per year. The whole Reykjanes Peninsula is an expression of this.
I always felt there is a lot more to come from this Volcano.
Fascinating. Such vast forces at work beneath the ground, and so far the signs on the surface are on a much smaller scale.
My theory is the sub-surface models are wrong. What they are calling magma dikes and intrustions are really pockets of compressed gas squeezed into the narrow gaps or cracks from the quakes and broken rock that have become suddenly decompressed, and the sudden decompression causes gas or air molecules to form pockets that seek to find a way out and up into the atmosphere above ground. If all that magma they say is down there, and the eruption happens, why does most of the magma not appear at the surface. Because the modeling is wrong, thats why.
I really 'miss' the first 'tourist ' eruption Bob....these current eruptions are devastating for residents and businesses. The uncertainty of when and where, must be really taking its toll. Preparedness and planning to protect the community should be paramount. Stay safe.
Yeah, me too. It was such a beautiful and peaceful eruption. Hopefully we'll get something more from Fagradalsfjall.
Fasinating and devastating. Take care.
Thanks, will do!
If it wasn't so thermally challenging the Maldives would love to have that land building problem.
Thank you ! Be safe
Thank you! Very informative. I am so ❤blessed to have visited iceland and the blue lagoon.
Iceland definitely has some unique experiences to offer
Appreciate all the numbers and comparisons to previous events. Ill keep watching all your videos, keep it up!
Ayy, thanks! Glad to have you on board
Not only will this cycle continue. Several experts have suggested this will continue for decades. Yes decades.
Yep, it's unsettling to think that could be the case
It's not definite that it will continue for decades, but it is a possibility.
@@michaeldeierhoi4096 Actually I like to think the area is returning to geologic normal. The 800 year lack of activity in geologic terms is a mere blip. Given the position along the Atlantic Ridge, and the other active volcanism on the Island, it would be easy to assume that 800 year gap was the real anomaly. The upwelling under the ridge apparently begins about 400 Km below the surface of the mantle forcing the plates apart. Yet only in the one area (Iceland) has the material pushed up and out to create land. That location (The Iceland Plume) is very active still. Heck the whole land mass is only 20 million years old (again a toddler geologically). And since humans only settled there about 1200 years ago, that 800 year gap may have been an unexpected blessing. As long as that plume exists and it keeps pushing up Magma, well....
@@walterengler5709 We all kind of have a front row seat as this plays out. It will probably continue to be fascinating to watch how it develops and it also is a growing disaster for the residents on the peninsula.
ReadyTemp Intelli-circ eliminates waiting for hot water at sinks and showers and is often used to prevent water pipes from freezing.
I live in Oregon, USA near the Columbia River within sight of two volcanoes, Mt. Adams and Mt. Hood. To the northwest is Mt. St. Helens which blew up rather spectacularly in 1980. So, as one might imagine, I'm always interested in volcanic geology and informative postings like this are very welcome. Thank you.
Thank you for the information. The november 10 event was really large, no wonder Grindavik was more or less torn apart. Meanwhile many inhabitants face another cold night. I hope some warmer airflow will come your way until the hot water supply is restored 🙏.
Yeah, so mind blowing.
We're actually super lucky with the weather as just one day after the water went off temperatures climbed above freezing.
I always blessing the great Spirit when I stand in Wintertime under a hot shower and can be in a warm Apartement I know it is not so natural like many think.
I feel with the people in Island hope it will be very soon fixed for them
Good information on the eruptions. Thanks.
Always good to have a backup available. I guess the only downside is if those pipes with no flow freeze. Hopefully, they are below the frost line.
Yeah, hopefully. We're also really fortunate that temperatures began increasing the day after the pipe ruptured.
Thank you for this very informative explanation of the data & facts leading up to these eruptions. Now that Sundhnúkagígar has gotten its three eruptions (like Fagradalsfjall in the previous years), what would be the next system likely to go off? And would any of those other 4 volcanic systems on the Reykjanes Peninsula cause even more trouble?
It would be nice if it just shifts back to Fagradalsfjall again, as that was such a well-behaved volcano ;-) The eruptions there were well contained and relatively harmless...
Yeah, I agree, would be great to have Fagradalsfjall return again with a chill eruption that doesn't hurt anybody.
@@Hliarmenn Especially that first one in 2021, with those mind-boggling twists & turns over its 6 months period of activity... Crazy times! Perhaps they could try to divert the underground magma tube plumbing towards Fagradalsfjall too 😂
Thank you for this video. Greetings from the Netherlands.
Well done video. I guess some bumps in the ride should be expected when you are surfing a giant lake of lava on a surf board made out of that very lava.
Hahahah, well put😂👍
Gotta Love Iceland. ❤
Love ❤. Shared ❤. Saved on UA-cam ❤️.
Thank you for another informative update! 😊
You are so welcome!
Thanks for sharing, I hope repairs are available soon and future proof (survive the netx set of eruptions that will probably happen untuil inflation stops)
sehr gut, das die erde den überdruck ab lässt! ich denke, es kommt demnächst noch viel mehr raus!
Yeah, definitely, who knows how many eruptions we'll have to endure.
I think it's clear that the eruptions are happening where they are because of the fracturing of the ground in past eruptions over history. What is puzzling is that there has been so much land rise and uplift under the Blue Lagoon and power plant without any apparent damage to any of this structure. Huge damage was done in the town just by ground movement, but none of this kind of damage has been done at the Lagoon or power plant despite comparable uplift. Why is this? I have studied the area on Google Earth, and you can see the huge network of pipes spidering out from the power plant to all of the bore holes it uses to collect its heat. This area where the bore holes are located seems to coincide with the area that is subjected to the largest uplift, yet no damage to them is being reported. It seems very strange to me that the area could be subjected to so much uplift, yet the levelness of the water in the lagoon seems to be unaffected. What are the chances of the whole lagoon being subject to that many rise and falls and still remaining as level as it was built, when the town is destroyed? My theory is that because of the decades of removal of heat by the power plant in that area, this has caused the ground below to harden and the power plant, Lagoon and the whole area covered by the bore holes is effectively a solid floating raft on the magma below. I agree that any near future eruptions are likely to be where the have been now and may well destroy the town. If they migrate anywhere else, i think they will be to the west of the power plant and lagoon. I don't think the power plant and Lagoon are in any danger from an eruption within that area, the only danger is from surface lava flows from eruptions outside the area covered by the bore holes. The ground below the power plant is now so hard because of cooling that an eruption will be forced to find softer ground elsewhere. Hope this makes sense.
The reason the Lagoon and power plant haven't been affected by the uplift cycles is because they don't sit on top of the dike that formed on November 10th. Grindavík is unfortunately situated directly above it which is why it's so heavily damaged as when intrusions occur, land close to the dike is torn apart and is subjected to much greater levels of subsidence, up to half a meter or more in some cases.
The uplift directly above the chamber is more uniform and "chill" and the power plant and the Lagoon are lucky to sit there.
@@Hliarmenn Agreed. But isn't it strange that even the bore holes of the power plant don't seem to have been effected? I've seen maps where the highest land rise has been to the west of the power plant, yet the eruptions are to the east of it. Seemingly magma can migrate from one side to the other with no effect on the power plant or it's bore holes. The ground below the power plant and it's bore hole field has somehow managed to stay in one piece, despite an obvious flow of magma beneath it. My only explanation for this is that cooling from the heat extraction has somehow made it stronger. Maybe this is what's going to protect it.
@@General_ConfusionOne main reason is that the magma under Svart Sengi PP and Blue Lagoon is at a deeper location 5k down, than the dyke to the east. But that is merely a guess on my part.
Thank you for very good explantion.
You're welcome 😁
Awesome video and update! Thank you very much.
This is truly a very interesting event that is happening in the Rakijanes peninsula, (I apologize for my spelling)
Very interesting for us volcano lovers but also very sad and of course more than frustrating for the town of Grindervik and the people of Rakajanes.
My heart goes out to you all especially because of the uncertainty of what the future will hold and it been winter.
Icelandic people are very hearty and resilient!
Stay strong, take care and be safe.
My prayers are for you and lots of love from New Zealand.

Thanks!
The crack was big and the pressure was released fast
Great job! Thank you very much!

🌱🌏💚 KiaOra. Hellooooo Hlidarmenn! Thank you for sharing the science paper link in your description. Shared, your videos & links are excellent resources. 🙂
Ayyy thank you so much Amelia!
@@Hliarmenn 🥝🙂
Thank you
Excellent information
Thank you!
Given the price of electricity lately. Those things can get expensive.
Excellent video thank you very much
You are welcome!
Is is so nice of you to mention Just Icelandic also. :-) This is the 2nd time I hear you do that. :-) The two of your channels is the best we got, calm and with the facts, details, and from people living on Iceland. :-) Time for prayer for Iceland, since this is the most serious thing that has happened to you all. May God bless you in the Mighty Name of Jesus!
Yeah, hahaha. He's really trust worthy and is so good at delivering content.
Thanks for taking the time to watch the both of us 😁
I'm curious, why there was no barrier built between Stóra-Skógfell and Sýlingarfell? I'd think this would've been an urgent consideration given that the most likely eruptive sites are just east of that area between the two mountains and that any lava would follow the topography down towards the infrastructure as we just witnessed. Any reason why they chose not to do that?
I think that on the sloping terrain the barrier could never be high enough.
Yeah, @chocoladehagel is right, the terrain between the mountains is slopy so lava would just pile up and flow over the barriers. They could've still been built and maybe do just direct the lava in a slightly more favourable position or to just slow it down. I guess our experts didn't expect lava flows to reach that far.
Thank you. I am not a geologist but I did read the science paper and still cannot wrap my mind around how the magma could reach such speed and power. What was the pressure per square inch....and how did the pressure get that high?
I'm not sure how much the pressure was per square inch or meters, but the reason for these enormous amounts of pressure is due to the plate boundaries on the peninsula which a so called Transformer boundaries which means they are rubbing against eachother.
That creates a lot of pressures which builds up for the 800 years between the volcanic periods on the peninsula.
When a volcanic period then starts, this pressure is released mostly during the first intrusion.
When these eruptive events began in March of 2021, I heard mentioned that this was a first event of its' kind in 800 years or so. Additionally, I was hearing reports to the effect that geologically speaking, Iceland would endure periods of some 1100 years of activity. To your knowledge, does Iceland experience episodic eruptive cycles of 1100-1300 years on, and 700-800 years off?
I like the style of your reports BTW.
Yeah, that's pretty much correct, although, the cycles last for around 300 years not 1100-1300 years with 700-800 year long breaks
@@Hliarmenn Thanks for your answer. No matter how you slice it... Icelanders are going to be living on the edge for lots of lifetimes to come. Yikes!
My thoughts; always look back at history-there was historically a very long period with constant eruptions on the peninsula and volcanic activity tends to be cyclic so we might be up for a new period of constant magma intrusion and new fissures! Maybe it’s best to completely abandon the Rejkanes peninsula for the safety of the people living there, or at least start planning an evacuation ??
It should not be necessary to abandon the whole peninsula as, even though this is a tough situation and will cost a lot, I think it's better to try our best to save all the important infrastructure that's on the peninsula.
This looks so spectacular! It's like the whole earth has split in two to let the magma out!!! Iceland is obviously still forming and it is magnificent. Obviously it isn't nice for the people who have had their homes destroyed and lives disrupted though! Luckily everyone was evacuated in time.
Yeah, this is definitely a spectacular event that shows us earth's power.
@@Hliarmenn I am English but married to an Italian man and live in Sicily. We have visited Mount Etna many times, even once when it was erupting. I love volcanoes and find them so beautiful and fascinating. Volcanoes destroy, but they also give back to the earth. Lava rocks can be used to build things, the soil around volcanoes is very rich with minerals and plants fruit, trees etc are lovely and grow there. Souvenirs are made with lava rock from Etna too. Volcanies are truly a magnificent and amazing force of nature continually changing our lives and world.🤗❤️
Time to move, the quicker the better. Are there any house movers in Iceland?
The people of Grindavík have all moved for an uncertain amount time. People that were now affected by this eruption will probably not move as this will be fixed. Some are staying at relatives elsewhere in Iceland during the time the hot water is out
Thankyou
One thing I don’t understand: protective dams were built to protect the Blue Lagoon. Why not the pipelines?
I think it was hoped that lava wouldn't reach this far and also, they pipes are not easy to protect as they're so long and in a bad location where walls wouldn't be able to redirect the lava efficiently. The walls can't stop the lava, just redirect it.
There was an effort to have a backup pipe if this where to occur which they buried 2m under ground. It almost worked but the Lana managed to destroy it too.
You live on a volcano don’t take it for granted all infrastructure should be beefed up and research should be done on areas before building. Just because the volcano hasn’t been active in years dose not mean it won’t erupt again.
Yeah, it's definitely strange how little preparation has been done in terms of lava protection on the peninsula, the government has been enduring quite a bit of criticism lately because if that as geologists have been warning them for years.
Hi there. All your piping - does it have el-tracing to keep it above freezing ?
Not all pipes are heated and if they're without water for some time when it's below 0° they'll get damaged. But we're really fortunate as temperatures in Iceland are on the rise so we may just have gotten away with it.
So a 27 day lunar cycle (28 actually but close enough). The last new moon was 9 Feb. when the sun and moon line up and exert the most force. The next one will be 10 Mar.
best video in world
Thank you, 😊
You're welcome 😊
Can you please explain how the February eruption 🌋 de not effect Grindvik ??
Grindvik and Hahafel must be two different volcanic systems??
Please advise??
The eruption took place far away from Grindavík meaning lava didn't threaten the town.
There was also no noticeable damage due to ground deformation which is because the intrusion that caused this eruption went straight up in a very short time and didn't spread out like for example in Nov 10th.
Mt. Hagafell and Grindavík are not volcanic systems on their own.
All the lava in the area is from the Svartsengi system with Mt. Hagafell was forming during the last Ice-age some 10's of thousands of years ago.
Hope that answers your question. If not, feel free to let me know and I'll try again 😉
Thanks for keeping up with what is going on with this latest of volcanic eruptions on the Reyjanes Penninsula. There is some difference of opinion in the details about the latest eruption. You stated the rate of the eruption occurred at 400 m³/sec initially. Another channel said it was 1000 m³/sec initially. This other channel also said the total volume of lava erupted was 22 million m³ while you said it was 10 million m³. I'm not in a position to verify the veracity of either statement, but maybe more will be revealed later that can confirm the erupted volume rate and volume.
Other statements on this video were of interest to me such as the difference in the eruption volume and height of lava of the first and third eruption vs the second one. This may continue to be consistent, but there is too little data to be sure. And also the massive magma intrusion data from Nov. 10 was also revealing. If that had erupted then it could have been even more devastating.
It is quite unsettling, but also fascinating that this eruptive activity could continue monthly and indefinitely. And what happens if Krysuvik wakes up too??
I actually think the numbers I stated were a bit off, the actual volume was 15 mil according to our Meteorological office with the peak discharge being around 600 m3/s. I thought I'd read somewhere that it was 10 mil and felt like that made sense as this eruption did not seem that large.
This means this eruption steals the first place off the Dec 18th eruption.
Krýsuvík snoozing at the moment and it's not certain when it'll wake up. It definitely will though that's for sure, could just happen after 100 years.
@@Hliarmenn Thanks for your response. Keep up the interesting updates.
Dang and holy heck. Those numbers on the dike intrusion on November 10 gave me chills. Just imagining what could have happened is terrifying. I mean, imaging a 15 km long fissure eruption happening in the area that day.
As for the intrusion now, so the eruptive volume is 10 million cubic meters? That's a bit less than the initial 15 million estimate. Either way, the magma inflow would still be about 8 cubic meters per second. Some like @GeologyHub estimate it being 5 cubic meters but I find that low, seeing that uplift is 8 mm per day, possibly a bit more now. So, seeing that uplift is roughly 8 mm, possibly more, I'm estimating magma inflow to be about 8 to 10 cubic meters per second.
Yeah, the initial 15 mil was a bit high as this eruption was smaller than the Dec. 18th eruption which clocked in at 12 mil.
I agree with you on the uplift and influx of magma, especially now as the uplift seems a bit accelerated so influx could be up to 10 m3/s.
Whether that'll result in a shorter time between eruptions is going to be interesting to see.
@@Hliarmenn I just trying to figure out why these eruptions last 1 or 2 days. That's good news but also a bit strange. I know eruptions can last from hours to days, weeks, months or years but still, these eruptions seem short. Especially considering that the magma inflow is about 8 to 10 cubic meters per second. If the magma conduit remains open and stable, eruptions should last longer.
@@sigisoltau6073 The erupted volume appears to be determined by the size of the magma chamber which it erupts from. It is a very ominous circumstance however that this magma chamber moves around and erupts in a different place though the 1st and 3rd eruption were from almost the exact same location which may become consistent. Time will tell!!!
@@michaeldeierhoi4096 Magma chamber stayed in one place under Svartsengi. Once the pressure was high enough the magma moved along a weak zone into the dike area that formed on November 10.
I believe the 2nd eruption on January 14 was a separate intrusion unrelated to Svartsengi.
🥝🙋🏻♀️ KiaOra Sigi!
Have we heard if the system set up in the power plant was able to provide warning?
Yeah, there are sensors at the bottom of the boreholes which have been able to detect the movements of the magma when it's intruding really accurately which is really interesting. Will be exciting to see if this be a topic in any future paper.
I have a feeling that what is meant is that they do not get ANY water - hot or cold. The water they have always had was piped hot water from the ground from thermal areas.
Their home heating systems use the heat from that water.
This is continent building here before our eyes. Iceland is on a spreading zone. We have been seeing the poles move at an increasing rate, which can only mean we are upon a reversal of the poles and all that entails. We are seeing it in the ring of fire becoming very active, the opening of the east Africa rift, and more. We are watching history happening.
It's not continent building, it's all oceanic crust in Iceland. Once the hotspot moves on in a few tens of millions of years, the whole place will sink. No one knows whether the recent wandering of the magnetic poles has anything to do with magnetic reversal. Magnetic poles normally wander, they were just slow for a while. The ring of fire is no more active than usual, we just have better communications to find out about it. The east African rift has been opening for tens of millions of years, and some geologists believe it is permanently stalled. There's a lot of cool geology stuff going on, but there always is. Now that we can view so much of it from our comfy chairs, and understand so much more about it due to advances in science, is a good time to be interested in geology.
And the pipes freeze and burst. Then you have to replace how many pipes, cold and hot water.
That's what we're fearing the most. Hopefully we got lucky as temperatures went up above the freezing point one day after the hot water went off.
How are they even coping!?!?
It's definitely a difficult situation. The strategy seems to choose one room to live and sleep to get as much heat, all windows are of course closed. The way people bathe is by going to swimming pools elsewhere like in the capital where they'll have free access while this situation remains.
Just saying the December 18th eruption lasted 3 days and spewed out 12000000m3 and it was spewing around 400m3 per second but the February 9th eruption or 8th forgot when it was but it released 10000000m3 and so it most likely would have been spewing around 1000m3 per second that makes much more sense
The peak was estimated to be above 500 m3/s and that output lasted for 4-5 hours, meaning 7-8 mil m3. Then, the eruption declined rapidly, but 500 m3/s is definitely a lot.
@@Hliarmenn geologyhub was the channel who put this out but that’s a estimate so it could be a over or under estimate
thank you, interesting update. Is there any informed debate about the likelihood of systems related to Krysuvik or Hengill waking up ? - I heard that in the past they tend to go off in similar geological time frames to the other systems on the peninsular.
They've gotten a few mentions and it's almost certain they'll erupt, but that could happen after 50+ years as this eruptive period we're in is likely to last for 300+ years.
@@Hliarmenn thanks for answering - glad there's no apparent threat from them for now
Why does Iceland exist? I believe it's the only place on the planet where a mid-oceanic ridge is above sea-level. Why would that be? Is the ridge churning out granitic rock instead of basaltic rock? If so, why? Or is some sort of unusual pressure pushing the ridge upward above the sea floor? If so, where would that pressure come from? I think the only other place that comes close is the Azores plateau, but in that case only a few tops of seamounts poke above the water level.
The reason Iceland exists is because of a mantle plume(hotspot) that sits under it which increases volcanic activity drastically.
That allowed Iceland to climb out of the ocean some 20 million years ago.
Is there any correlation between these eruptions and the phases of the moon? Seems as though the New and Full phases line up with recent outflows but maybe just coincidence. Nice update and thank you.
It does look like it, let's pay attention to the date of the next eruption.
If you have events that happen at roughly 4 week intervals (27 days) they can't help but sort of line up with moon phases, all the more so if you figure that within a week or so of either new or full moon is close enough to be significant. Like a recent comment elsewhere about the significance of these past three eruptions all starting at night.
There are hundreds of active volcanoes around the planet which haven't shown any significant correlation between lunar phases and eruptive activity. Here's an excerpt from a Wired article to that point.
"The Moon plays a very small role in increasing seismicity and volcanic activity on Earth - potentially increasing activity ~1% during full/new moons.
The change in the gravitational pull from the Moon during apogee and perigee is small.
Beyond this, there is no statistically-sound evidence that geologic disasters can be predicted based on lunar alignments or distance".
What caused the drop in density you mentioned?
If I understand it correctly, as the magma rises, gases come out of solution due to reduced pressure from the mass of the overlying rock. This lowers the density.
An arcane question - every time I look at Grindivik from the (th)orbjorn camera I see a single blue light in the center of all the white lights. What is that?
I unfortunately don't see it, could be lights on the football field or something at the harbour.
It would appear as Iceland placed all of "their eggs in the same basket" as we say in America, you could and should diversify your immense land with some solar panels. The homes roofs are very similar to here in America, imagine the energy you could develop for emergencies?
They've got only a few hours a day when the sun is just barely above the southern horizon this time of year.
Maybe a combination with windtubes would work?
@@b.a.erlebacher1139
It's correct that solar energy is pretty unreliable in Iceland, especially in the winter. Wind power would definitely work but it's still being discussed and planed by our government.
How many more months will this carry on?
Unfortunately it's uncertain. The only way to find out is to wait and see.
Months? Some scientists mention years.
I was thinking of visiting in the summer. Should I cancel?@@stevet.3630
Maybe the lava well push up gold or diamonds.
Since the crust under Iceland is young and unstable due to the mantle plume under it, diamonds can't form.
Gold on the other hand could be possible although the amounts are were little.

They get their hot water for free?
No, it costs but it's way less expensive than electrical heating or other alternatives.
sooooo…. umm, what did yall do to acquire hot water out there for 800 years before modern technologies of piped in hot water came to your island? I am curious and not trying to be rude. But sometime curiosity can be considered rude. And I am curious about history since yall have been there for so long. And yall survived, to boot! So… yall might to have to get hot water in the olden ways while they rebuild the pipe. And therefore I ask again, what was the olden way of getting hot water before modern pipes came to Iceland in the 1800s?
People back then didn't know how to extract this hot water. Iceland was really under development until well into the 20th century.
The only way they'd use this hot water was by waking up there to the hot springs to either bathe or wash clothes.
How long will a baked potato take???
That's a damn good question!
We are coming to visit next week so I'll bring a potatoe an tinfoil 😉😉😉😆

Could it be the eruptions are triggered by interaction with the sun's and the moon's gravity? The eruption dates line up pretty closely to new moon when the sun and the moon are in the same direction in the sky and their combined gravity is strongest. The lunar cycle is about 29.5 days so you'd expect the next eruption around march 9.
Oh, great, another armchair scientist with a degree from the University of UA-cam. So now we're blaming volcanic eruptions on lunar phases, are we? Forget about actual geology and seismology, let's just consult the almighty moon calendar. Next thing you'll say is that earthquakes are caused by someone sneezing on the other side of the planet. Keep up the groundbreaking pseudo-science, Einstein.
Definitely strange how the dates line up perfectly.
Will be interesting to see if it lines up again.
The following is an excerpt from a Wired magazine article.
"The Moon plays a very small role in increasing seismicity and volcanic activity on Earth - potentially increasing activity ~1% during full/new moons.

@@michaeldeierhoi4096 Well, perhaps we'll get some statistically sound evidence now. We do know that there is a 6 hour cycle in seismic activity in Svartsengi before an eruption occurs, there is no other explanation for this cycle than tidal forces. And the change in gravitational pull during new moon and full moon might be slight but it's enough to cause spring tides (perigee/apogee syzygy is the difference between a "super" full/new moon and a "micro" full/new moon).
🙄 Wow, "exciting discoveries" about a volcano erupting... groundbreaking stuff, guys. 🌋 Can't wait to hear what you've uncovered this time! 🕵♂ Maybe it's that lava is hot? 🔥 Or that volcanoes tend to erupt? 🤔 Keep those groundbreaking updates coming....🙄🙄🙄
Perhaps you would like to go to the Icelandic Meteorological Office website which has a link to the Science journal article detailing the discovery. Perhaps the numbers given in this video have not yet sunk in, or perhaps their significance is not clear to you. I do not know what more can be written or said to encourage you to do the work of imagining how details hard won by research into specific eruptions might be important for those who live and work on or near volcanic regions. I hope you'll take some time to reflect on it. All best wishes with that. 🤞
