Iceland Volcano Updates | 4th Largest Jökulhlaup since 1918 

Agreed.😁

Hahaha. It's definitely an interesting island

I´d go with "weird names ONLY locals can speak out". Fully on board otherwise, have a nice day

I told my wife just before I read the comment thread, "I LOVE how this guy says these names of things that my brain can't even recognize how to make my mouth frame itself to make the sounds of the letters baahahahahahahahahaha And yes... I second, move, and carry all your points!!

Ayyy, glad you like the videos! We've definitely gotten good at handling these situations. At this point we're mostly annoyed when they happen, not scared 😁

@@charlesward8196 hahahha

Yeah, Jökulhlaup has established it's self as the word to describe glacial outwashes in the geologic community as they happen so often in Iceland

If only the Icelanders could have found a word more pronounceable by the rest of the planet! 😛 Thanks for the video and the explanation. 👍

Then again, compared to some of the town, glacier and mountain names, this one is quite tame! 🙄

There's definitely something different about this Jökulhlaup compared to normal ones. Could be that something changed in Katla's geothermal system which caused increased melt, we just can't tell at the moment. It's true that it's been said an eruption could occur inside Grindavík but that's only a could. It's still way more likely it'll just occur in the same spot as last time as it seems to be much easier for the magma to surface there. Each time magma has searched south, the intrusions last longer an lose puff. Those intrusions do however cause extensive damage to Grindavík as the ground deformation is much greater when the intrusions last longer.

You're welcome 😁

Hahaha, that's the best explanation yet😂

Glad it was helpful 😁

It depends on what you call difficult 😁 We grow up with this so it's a bit normal When something happens we deal with it fast and safely. Most of us don't think about this unless something happens....something big. We're used to small eruptions recently. BUT there are few volcanic systems that are overdue....those are the big ones!! The 1783-84 catastophic Lakagìgar eruption cooled earth's temperature be 2°c. Killed 8700 people but estimated up to 2 million died. The ash and gas coverd northern hemisphere and crops and hunger spread widely Many say that the 1789 French revolution is the aftermath of that eruptions So we have some nasty ass volcanoes But no worrying helps so we tend to think about elves instead for example 😁😁

Ayyy, you're welcome! That's correct, this event does release a lot of weight of the system and it's possible that it could result in an eruption. Fortunately, that doesn't seem to happen often in Katla, atleast not in recorded history. However, it is known to happen in the more active volcano Grímsvötn. We could be about to get a Jökulhlaup from there soon and then there would be a major risk of an eruption as that volcano is well due

Yeah, it's scary to think what Katla could have in store after such a long break.

Will do!😁

@@rickc4317 you're welcome 😁

You're welcome 😁

Yeah, it's definitely a possibility this will effect Katla and possibly trigger an eruption in the near future although I think we haven't seen any relationship between Jökulhlaup and an eruption in Katla's recorded history like we've seen in Grímsvötn. Katla is Iceland's most consistently explosive volcano with almost all eruptions being between VEI 4-5 with it's largest eruption being a VEI 6.

@@Hliarmenn What was that VEI 6? Was it the Eldgjá fissure eruption? That was its most voluminous eruption counting its effusive components and apparently included at least 16 Plinian and or Sub Plinian eruptive phases even if it was predominately an effusive fissure eruption like Laki. That said Eldgjá was unlikely to be the first such fissure eruption of Katla as the mid ocean ridge fissure lineament faults seem to get reused periodically and it is one of the main hot spot associated central volcanoes which falls along the area where the MOR cuts ashore the others being Grimsvotn and Bardarbunga. There are also those caldera complexes of Askja and Krafla and there are probably others too but they are further from the core of the hot spot. Looking into the MOR extension stuff is fascinating. As is the Icelandic hot spot which I have recently learned can be traced back further in time than the North Atlantic Large Igneous Province as it had passed through Greenland and far Northeastern Canada where it appears to have played a role in the rifting of Greenland from North America. The hotspot it seems is related to the Large Igneous Provinces which together are collectively known as the High Arctic Large Igneous Provinces the oldest of which dates back 130 million years. Modern Iceland dates back 20 Ma but it appears to merely be the youngest chapter of a long lived hot spot which has driven the formation and gradual quasi-quiescence of the Arctic ocean, where the modern spreading center Gakkle Ridge has one of the slowest rates of sea floor spreading of any active MOR system known so far leading to melt pooling up and undergoing crystal fractionalization which ultimately builds up deep sea stratovolcanoes and caldera complexes, and the formation of the Davis straight which appears to be extinct since the collision of Greenland with North America, and then finally the North Atlantic which it seems is currently being fed/energized by the plume.

Sorry, I recalled incorrectly, Katla's largest known eruption is a VEI 5 since, of course, Eldgjá's output doesn't put it on the explosive list. Thanks for sharing this those interesting fact regarding the Icelandic hot spot, it has such a rich history due to all the land that has passed over it. What I would do to see a time lapse of it's creations over the last 150 mil. years.

Yeah, really interesting to watch. This shift in earthquake activity might be showing us directly where the geothermal system is changing and if so, it's changing over a large area.

@@Hliarmenn i was thinking similar lines, but more for melt water and the glacier dropping after the water has moved off

bit more active today on the Reykanes ridge leading inland couple 3's will check back in couple hours and have another look see if its going to be enough to trigger before August... will just have to wait and see 😅

They have a lot of similarities. There are some minor differences like the fact lahars can form without glaciers and have much more debris in them. Jökulhlaups can only form in glaciers.

Thanks for tuning in 😁

@@ladycircumnavigator hahaha, you definitely can't rule out the eruption scenario, you're trip might get really exciting 😁 Hope you have a great stay!

Ayy, you're welcome 😁

@@EducatedSkeptic ayyy, a pleasure to know that line hits home😁 Will be interesting to see how Katla behaves in the next couple of days. Thanks for tuning in 😁

You're welcome, thanks for tuning in 😁

Ayyy, glad you like it!

@@Shobo11 wow, these floods are something else. I can't imagine what Katla's larger floods look like but their discharge can reach as high as 400.000 m3/s which is twice that of the Amazon river.

The accumulation actually began 5 days into the eruption, so June 5th. That makes it 55 days if I'm counting right and thus 3.7 m3/s average influx. The reason this number is so low is likely because 25 of those days are when the eruption was still ongoing.

@@Hliarmenn Did some recalculations. On July 1 it was about 8 million, on July 28 it was 18 million. So over the roughly 26 days or so 10 million cubic meters built up. If correct that equals roughly 4.5 cubic meters. Though, seeing the GPS data it could be more like 6 cubic meters. Since there was no uplift during the eruption, and for about a week after, with a steep rise, I think I could be partially right about the cracked and stretched rock. Also before the last eruption started, in the 5 days before the eruption 2 million cubic meters were added to the magma chamber or sill. That tells me inflow increased in those days. Though, seeing the uplift rate, it's possible inflow is more like in the 5 to 6 cubic meter range.

Than means it still has plenty of puff left

@@Hliarmenn Writing this from my other account, main one has been temporarily blocked because someone falsely reported me for hate speech. All I said was in that AI generated video was that it was fake. Some people see the slightest thing as hate speech these days. Anyway. Yeah it might last a bit longer. See, the November 10 earthquake swarm and dike formation alone stretched and cracked the rock in and around Grindavik up to the Blue Lagoon and Svartsengi Power plant. On the AfarTv live stream there's a ridge that runs next to the road leading from the Blue Lagoon area to Grindavik, it has a large crack in it that formed on November 10. It's possible that the crust has been stretched and cracked to the point that there needs to be a certain amount of pressure in the magma chamber or sill before the land starts to uplift again. It's possible that the volume in the magma chamber may have already hit 20 million cubic meters.

Oops I meant thank you lol

Hahaha, no problem, we're sometimes mistaken for each other 😂

@@Hliarmenn lol

People are responding all around the earth, and they are saying 🖕🏽
