I'm confused I thought this was posted just an hour ago.

What was the error?

The previous version of the video had the islands on boundary of the North American plate and the Pacific plate.

Glad you fixed it man, keep up the good work

@@scottcary1 shows you are right there at the minute of upload. You are good community member! Nicely done. (also thanks for the info, that would've irked me no-end)

I was there traveling last summer. Superb museum documenting the event built around a few excavated houses. I was flabbergasted to find that the local legend of the bread-baking possible at the summit is still true. I dug down 6” with my hands at the base of a seemingly cold and dead fumarole and suddenly had to snatch my hands back- still hot!!!

Not trying to be a dick but I'm pretty sure it's called volcanology

@@blake1453 You are not wrong about this question, however I was referring precisely to the volcanism phenomenon and not to volcanology, as the latter refers to the study of this phenomenon.

Didactic. That's an excellent word. Thanks!

There is a detailed documentary about it if you want to look it up.

I wonder if they could also engineer systems to deploy very long, durable hoses (perhaps by airplane or helicopter) to more inland areas to use the same technique (along with very powerful pumps). I feel like the combination of explosives to blast particular paths in the flows and water to cool particular points, in conjunction with models to help with precision, could legitimately help mitigate risk of effusive eruptions in some areas. That being said, humanity could also just try not to build on volcanic systems quite so much...

@@StuffandThings_ Look up the documentary, they did use explosives, but they dragged hoses and sprinklers over the lava.

Icelandic people are hardy, very intelligent, and resourceful. My wife and I loved the country (and it’s volcanic geology) and people so much we returned twice more with a fourth trip planned for this fall. Go see the northern lights!

I plan to visit Iceland when the next volcanic eruption occurs there. Even if that means going to a highly remote site like Askja!

@@GeologyHub that would be so cool, you’ll love Iceland, I guarantee it

Holuhraun was the first time I really followed a volcanic eruption even though I was young at the time. I was hoping to try and visit during Fagradalsfjall but unfortunately the pandemic and the uncertainty of activity during the summer shut that down. Perhaps some day I'll see an Icelandic eruption...

Yes that is true, the eruption helped the island in general as the eastern winds were so extreme here when there was no mountain to block the winds. But now eastern winds are not so bad here

Small islands like that tend to erode into the sea pretty fast, so its youth is probably the only reason its even there. That, and the volcanic activity that keeps adding to it. Probably not smart to build on a young volcanic island though...

Well, the process has come a long way from just looking at it and guessing. All I know is that it's difficult and complicated.

I reposted it as the original upload contained a major error which has now been corrected.

@@GeologyHub okay

No. Greenland is part of the continental shelf, whereas Iceland is a volcanic island. Continents are a few billion years old, and do not significantly change (small bits are added sometimes, but that's it). What IS possible is that Iceland will eventually split apart if volcanic activity were to go down. If the island doesn't erode away into the sea (a process which, for Iceland, might take tens if not hundreds of millions of years, by my relatively uneducated estimate) and the plate movements change, it's possible one or both halves of Iceland might end up being one of those small bits that gets added to another continent. Another example of a similar event is Silesia, which was an Iceland-like island. It got gobbled up by the North American plate about 55 million years ago and now forms the Olympic Peninsula in Washington state, the area west of Seattle.

think more like New zealand where the plates are slowly ripping the island apart.. the same is happening in Iceland but as long as there's continued volcanic along the rift zone it'll continue to fill in the area. like Leyrann mentions, if that was to ever stop it would eventually split the island after millions of years. but alternatively the rift zone could shift east or west of the island.

@@sirmonkey1985 Not quite the same Iceland is the combination of the Mid Atlantic Ridge and the Icelandic Hotspot so the plate boundary is why Iceland exists as Volcanism in Iceland is more or less a supercharged mid Ocean ridge system. The rift does shift (In fact the hot spot itself appears to be moving south along the Mid Atlantic Ridge) This is quite geologically complex with evidence for the Icelandic hotspot being quite long lived with some models suggesting it goes back well into the Mesozoic possibly all the way to the late Permian as a potential candidate for causing the Siberian Traps though that is controversial of course. It does however have a track which traces it back at least into the Arctic where it contributed to the formation of the Arctic "ocean" before passing beneath Greenland and reemerging to split Greenland from Eurasia 56-55 Ma with the formation of the North Atlantic Large Igneous Province. This change in activity as well as what looks to have been a 2nd possibly 3rd mantle plume head coincides with a major reshuffling of Earth's tectonic plates associated with the end of Subduction along much of former Gondwana. In the newer deep plate tectonics models where the Crust is really just the surface of huge Mantle tectonic plates plume heads might be better thought of in terms of material being squeezed out along weak points to accommodate the reshuffling of tectonic Margins since the total volume of the Earth is constrained meaning the amount of convergent and divergent boundaries and associated tectonic stresses must be kept balanced. New Zealand and the Larger Zealandia like any continental crust in this model are more or less silicate glaciers riding on top of these thick Crust + upper Mantle plates and thus New Zealand and the rest of Zealandia are currently being spread further and further apart over geological time while recent behavior from the double subduction has begun to build up the zone of intersection thickening it at least prior to the formation of the Taupo volcanic zone back arc basin. The deep plate tectonics model is still being formed at this point as part of the ongoing new revolution of plate tectonics enabled by seismic tomography and observations of the deeper structure of the Earth and the current shallow plate tectonics models to explain various types of volcanic activity and deep seismic structures.(Basically it throws out a number of haphazardly applies and unphysical explanations such as slab windows and slab rollback as unphysical citing evidence that "slabs" are continuous down to at least the Mantle Transition Zone and thus are unable to form these supposed structures at least according to Glazner_2022. Instead this newer picture suggests we must look at the Earth system as a whole and the need to balance geophysical convergent and divergent boundaries as Earth's system's volume is constrained. TDLR we are still too ignorant of Deep Earth's dynamics but whole Earth geodynamical modeling is looking to change the game in much the way modern meteorology has changes Earth's weather prediction from a regional picture to a global system scale.

Yes the original volcano had a major error that has now been fixed

Thanks

The better to soothe your anger, and lull you to sleep, young boy.
