On this channel, I currently give updates on the current geological situation in Iceland. I also post videos on geology-related topics. If you're interested in the topics above definitely tune in when I upload!
All this uncertainty just shows how poorly understood this process is. For instance, where is all this magma coming from, and is there another area somewhere beneath the ocean, perhaps, that is experiencing subsidence? And if the Svartsengi area is experiencing rifting, how is the crust to the north and south coping with this distortion?
Thanks again for the updates. It’s fascinating, can’t believe how much Lava erupted out of that fissures. I have seen some unrest at Eldey, so my prediction is, there will be another eruption. So we are at the beginning again. Hope you all do well. Have a nice autumn! Hopefully some calm days!
Definitely not last looking at IMO prognosis End of inflow from depth: 2026-02-19 [ 2025-12-31 : 2026-04-16 ] (in 521 days) Magma inflow expected: 77.1 millions m3 left of a total of 186.7 millions m3 (41.2 %) -> 7 eruptions or less -> 231.3 millions m3 of erupted lava or less
Great summary of the eruptions so far...really puts everything into perspective. Should I get my beer and popcorn ready?....my guess success rate is abysmal...so I'll leave it up to the 'experts' lol.
The ground is still rising, so probably there will be a next eruption. It is hard to say from the surface, but it looks like the magma is creating more or larger chambers. I hope the main activity stays at the north end, there is capacity to accept more lava flowing.
Yeah, magma is still accumulating. This time, it'll probably have to reach 30+ mil. m3 before going off. Would definitely be nice to have it focused in the northern region again as you say, a much better location.
Thanks, Mr. Hildermen. I just watched Gylfi's report and although I enjoy his imagery, he didn't present the totals. Yes, I believe there is more in store for Reykjanes perhaps to the East. There's also the big players, Hekla and Kayla, unpredictable, but according to schedule, Katla is now 10 years from its last eruption. Big Barabunga and his neighbors have again been causing floods to the West. If they go, take cover. What goes up will come down in a wide cone around the caldera. Dig in and hope for prevailing winds in the upper atmosphere. But I would not be surprised if Swartzengi produced another 2 Mil cu meters of fresh lava northeastward. I understand the land slopes that way, and the suburb of Volka (?) could used a wall, just like the Powerplant and Grindavik. There is nothing yet known stoping the filling of the lower magma chamber that drives this fissure, and Iceland may be in for 200 years of these volcanic eruptions, as it endured in 2008 BCE. If you made it here, thank you. Please forgive how I butcher your language. I learn more about your island every week, and I appreciate your friendly voice offer an organized, data- driven presentation. Good luck and thanks for your reporting. Wear a hard hat if Katla blows its top, and keep your head down. 🇺🇸🇺🇦🇮🇸 ⛑️☮️🧙🏽♂️
Yeah, we should be paying close attention to the volcanoes you mentioned like Hekla and Katla, Iceland is quite overdue for an explosive eruption. Glad you like the videos and thanks for your awesome comment😁
It's hard to say if Fagradalsfjall will erupt again, it's been more than a year since it's last eruption and there are no clear signs of magma accumulation based on GPS data. But, we can't write it off yet, the time between the 2nd and 3rd eruptions was also a year.
I always forget to check if I can set them before I upload 😬 I unfortunately can't do it after I upload. Thanks for reminding me, I'll try to get it sorted 😁
I think this eruptive period in this fissure system will continue. I don't know why you said that based on the eruptions from 800 BCE that this eruptive phase should be over soon. If there is still uplift at the same rate as before in Svartsengi, I do not believe that statement to be true. I'd say more like "Wait and see what this system will do; in 800 BCE this much was produced, this time it could be a similar amount or more, but we don't know. I appreciate the maps and numbers in this video. It's hard to imagine the sheer scale of the new lavafields, and this helps me a lot. Cheers!
Yeah, the speculations based on the previous event are definitely far fetched, currently there are no real signs this is about to end as magma is continuing to accumulate in the chamber at the same rates we saw in the beginning. Will be interesting to see what happens in the coming months, the only thing we can do is wait and see like you say.
That's a lot of lava that erupted. I'm still of the opinion that the magma chamber volume may have been higher, possibly in the 35 to 40 million range. As for inflow, could also be slightly higher as well, possibly 7 or 8 cubic meters roughly. There might be some fluctuation such as after an eruption where in might be lower for a while. I mean, 85 to 120 million cubic meters of lava. Knowing that magma expands by 2 when coming up, that's 42.5 to 60 million cubic meters of source magma. So either there was more magma in the magma chamber, or the inflow rate is much higher than what's estimated.
Yeah, it really looks like there should be more magma in the chamber than our experts always state. They use the GPS along with other data to create simulations. These simulations might just be a little bit off.
@@Hliarmenn It's not not that I want to doubt them, but seeing how large this eruption was, in area, volume and general size, I'm taking some of this with a grain of salt. Let's say roughly 70 million cubic meters came out officially, that alone would suggest higher volume in the magma chamber and higher inflow. If either the 85 or 120 million estimates are true, then what the experts have been estimating may have been on the low side. By the looks of things, there's still enough strength left for at least one more eruption, possibly more unless it just stops literally at this moment. Though, I can't believe it's been about a year since those first uplift reports started coming in. Last year September, about a month after the Litlihrutur eruption ended, there were reports of recorded uplift in the area, though I can't remember if it was under the Fagradalsfjall or Svartsengi area.
Whenever the met office says an amount of xyz has accumulated below svartsengi since the last event, what they really mean is "added". If u eyeball the amount of deflation after eruptions and compare it to erupted volume and uplift you can get a better estimate about the total magma volume beneath svartsengi
Thanks for your informative update. The different volumes of material erupted vs. magma in the reservoir depend on the average density of the surface lava. It is full of gas bubbles and voids in the cooler flows, but I don’t know what is the total effect on density.
@@Hliarmenn Learn, learn, learn, be excited, learn some more, and all is said and done, get ready for everything else that seems to be on the cusp of waking up! Grimsvotn, Askja... I'd even take something from Hekla or Krafla~! Every time something happens, I just start looking at Google Maps/Earth just to look at what past lava flows were.
I think I've watched the cams with this eruption more than any other. That said, I am left with a burning question. Why are so many of the cars in Iceland white? 😅
Extremely informative video have been watching icelandic eruptions now for 3 years or more and makes for compelling watching every time I like the way the icelandic people are so calm and collected your all hero's in my book including isak and Gylfi. It takes true grit and guts to go out in all kinds of weather and film the action....all I can offer is good luck stay safe and good job from the uk 🇬🇧 to Iceland 🇮🇸
I don't think anybody had "Using Lava to clean up old ammunition" on their bingo card this year. Really wonder how much longer we are going to get influx into the Sill and Dike. Either way, its amazing we get to see what the first settlers saw when they arrived in Iceland. The Sagas often talk about erupting volcanos that are essentially right outside the city, and now we get to experience them ourselves. It's a great time to be a geologist and a Historian.
Yeah, hahaha. Our coast guards needed a little help. I often think about it as well. The Reykjanes eruptions back in the 11 hundreds are talked about a lot in old stories. It is even thought that they caused Snorri Sturluson, one of our best writers, to write even more as all of his cows died due to gas, which left him with a lot more skin😂.
@@Hliarmenn We give so much credit to Pliny the Younger as one of Volcanology's most important figures, but we so often forget those writers that aren't Pliny. The local Native American legends of where I am from in the USA original have stories about Mt St Helens erupting before the arrival of Europeans. (they wrote some of the stuff about St Helens as a Jealous lover to the nearby mt hood.) Here is to Snorri!
At the northern end of the lava field is a small valley whereby the lava field has pooled (Maybe around 5 - 10 meters deep ) this is why the lava field did not advance north (My thoughts)
Thanks for the update and explanations. I think the cartoon of the magma chamber is helpful but somewhat misleading. It seems to show an empty space above the magma during the eruption. It should show the chamber roof moving downward, as shown by the GPS measurements. I understand that is more difficult to animate but it would show the chamber behavior more accurately.
Thank you for the update. I wonder if the next eruption will be more to the north, where a path has been created. Would be great for Grindavik, but not so much for Vogar and the main road to the airport.
