Great, well-informed commentary by your dad, who I think it’s important everyone here know is a pretty much legendary sedimentologist/glaciologist, who seems to have been hanging around a lot of late with his volcanologist colleagues, because all his explanations here are authoritative! Was hoping this would happen again!

Thanks for your comment. My colleagues at the University of Iceland keep the team of Earth Scientists well informed - and you are of course correct in assuming I've been hanging around a lot with my colleagues, accompanying them to the eruption site and helping out with sampling and observations. We have probably not seen the end of volcanic activity on Reykjanes, more likely we are in the initial stages of a long-lasting episode of volcanic activity and can expect more eruptions in the near future...

@@sigisoltau6073 1) There is uplift/inflation still going on at Reykjanes, and 4-5 volcanic systems on Reykjanes are inflating. 2) The Fagradalsfjall dyke that fed both the Geldingadalir (2021) and the Merardalir (2022) eruptions had a depth of 10+km, was 8 km long and 1-3 m wide. 3) We will probably have a new eruption on Reykjanes in the near future, but it might start at a different location from Fagradalsfjall, as other systems are inflating. The Merardalir eruption can probably be regarded as the last (?) phase of the Geldingadalir eruption in 2021 as the magma was siphoned from the same source already in the feeding system. There is always a chance that a new vent might open up in Geldingadalir in the next few weeks, but I would not bet on it. Renewed seismic activity in the area will be one of the tell-tale signatures of a possible new eruption there. We are not there now. I hope this answers your questions.

The drone livestream from lsak a few days before cessation showed a sudden drop in lava in the spattercrater....it was like a toilet flushing (slowly) and l was amazed no one commented on it in the livestream (l couldnt...old phone only) the viscosity of the lava changed the day before too...
@olafuringolfsson9151

Thanks for your comment. The activity in the crater was a function of magma discharge through the the piping system, the geometry of the feeder channel and gas/degassing as the magma came close to the surface. These variables change in the course of the eruption, leading to more or less outpouring of lava, and more or less lava fountains. The viscosity of the magma/lava, which is dependent on its chemical composition and temperature, did not change much during the course of the eruption. What you observed was probably oscillations in the discharge/lava output.

I've been there😅! And I saw the eruption. It was amazing. But please my dear Icelanders: take care of the nature. If a new volcano erupts, start only guided tours to the volcano. Close the hiking track for people hiking alone. I was ashamed as I saw many people walking on the moss, beside the hiking track, on the 1 year old lava, ( its still very hot under the surface), they even left waste there 😤. And many people are not well prepared for the hike! With love from Germany

nice vid , the eq's in the area are puttering along atm maybe one an hour at most and they are not of a size that would be a cause of concern as they maybe caused by the land settling and sorting out all the stress from hundreds of tons of lava now plonked on top of it. will the latest fissure erupt again ? , imho id say no though i wouldnt rule it out 100% as everything there is now cooling and turning solid albeit slowly which may force the magma to travel elsewhere which may lead to a failed intrusion as we saw after the 2021 eruption where there were several cases of magma rising and travelling along natural faults and making its own paths through weakened rock layers but they didnt have the pressure behind them to break through to the surface. while the faf chart is atm showing signs of increase i am thinking that this is nothing to get excited about (watch it go boom in the next week !) but i think there maybe another eruption along the same line , is there another valley ? , i found it interesting that the fissure seemed to break out at the bottom of what looks like an older cone and seemed (from what i can gather) to be heading towards krysuvik , but that is joining some dots and making a leap of faith with added guesswork , but i did say that days before the last eruption ended it wont last months a few weeks maybe less and 4 days or so later it had stopped , atm im keeping a weather eye on krysuvik.

Thanks for the informative video. In the time scale of a human being, this had been two eruptions in 2 different years. But in the geological time scale, the eruption of this August had been just the second breathe of the new Reykjanes activity, that started with the first quakes in 2020 and the first breathe in 2021. Before that it was sleeping for hundreds of years. No one knows if there will be more breathes of that volcanic system, but is seems to be very likely. I hope the coming eruptions of the system will be as peaceful as these two had been. Have a nice day and best regards 🖐👴

My postulation on this points to a key clue that the initial magma was from the last eruption. I think what we are seeing here is the early stages of a crustal magma chamber formation.
@olafuringolfsson9151
2 жыл бұрын
Good points! I think you are right that the Merardalir magma/lava is a residual from the last eruption in Geldingadalir, and the eruption can be regarded as a continuation of the 2021 eruption. The magma composition is very primitive, pointing to a deep-source (close to the mantle-crust boundary), no signs of differentiation or partial melting of surrounding crust. Anyhow, large dikes and sills can be regarded as "baby" magma chambers, where the magma undergoes changes in composition as crystals grow and the magma interacts with its surroundings. I guess the next eruption will tell us if lava is from a magma accumulation within the crust or directly from the mantle-crust boundary.

@@JonBear Sure, visualizations are helpful. However, knowing how large a soccer field is does not necessarily allow you to understand how large 500 of them put next to each other are. The relation is lost at this scale. Anybody who has ever walked short distances on foot has a relation to a km or a mile. (I also balk at the American dumbing down of relating everything to a football field. But that's a different story.) Also, that was just me.
