Greetings from North Wales. It's always inspiring to watch your info. Thank you! 😊

It was very impressive to see the crews at work after the Svartsengi breakthrough. Luckily it was a bit cooler and slower moving lava. It will be hard to build new defenses, the lava is at many places higher than the wall, but Icelanders will find a way 👍

I think Heimaey is where they first tried to cool lava down. If I remember, it took them 3 months of pumping sea water to cool the lava flow.

I really hope that the experts are right and these eruptions will come to an end. On the other hand I thinks we may not see that much uplift because there are so many cracks and what not in this ground so the magma may fill up all this without triggering an uplift. On the Eldey seismograph we can see unrest and that is in my opinion the magma source. But let’s hope that nightmare is over now and you all can have a friendly summer. The biggest danger in my opinion are all these cracks and holes in the ground, especially in Grindavik. I cannot wait for another video. Stay safe and enjoy the sunshine. Thanks!

Ayyy, thanks for tuning into the videos! Yeah, it's actually interesting to think that every time an eruption has started, the weather has been really nice, clear and calm, which makes things easier/less uncertain in those hectic initial stages.

I don't think so. Currently the uplift is low, but I think it's because there was still magma erupting. The next few days will tell if the uplift rate has increased or not. If it does increase now that the eruption is over, which I suspect it may, then there's a real possibility of at least one more eruption. Also, just before the last eruption, magma inflow seems to have increased. On May 24 it was at 18 million cubic meters, by May 29 just hours before the eruption started it was at 20 million cubic meters. I think the inflow rate may still be in the 4 to 5 cubic meter range, but we'll need more data to see if the uplift rate will increase.

@@Hliarmenn I just thought of something, not sure if it's possible. What if these earthquake swarms, eruptions, and uplift cycles broke and stretched the crust that uplift doesn't happen as fast as it used to. Before each eruption land rose up, there was an earthquake swarm, eruption, and land dropped. That's what happened on December 18, January 14, February 8, March 16 and May 29 right? Each of these days had an eruption and was preceded by uplift, some by an earthquake swarm, know January 14 and May 29 had an earthquake swarm, but I'm not sure on the others since I missed the start of them. I'm including the failed magma runs on November 10 and March 2. Each eruption was also preceded by uplift. Now, I'm thinking that these earthquake swarms, land rise and fall with the uplift and eruptions, and the eruptions themselves, may have stretched and cracked the crust enough that uplift is now going on at a slower pace, that it responds slower after each event. I'm not an expert or geologist, is that even possible? What if magma 8nflow is still at 6 or 7 cubic meters, but uplift rate is slower after each uplift, eruption, land dropcycle?

The open-air part of the eruption is over. There may still be some flow through vents, you also have heaps of lava still under the crust that could emerge in random locations as the crust weighs down on it to squeeze it along the way. The crews may not get much of a break for a few more weeks yet before things truly settle until the next one.

Yeah, I miss those eruptions, they felt so peaceful. Like you say, it's just so uncomfortable to know how close Grindavík is to these eruptions and how much it's been effected.

Thanks again for a clear, complete review of the current situation . It's totally anticlimactic when the volcano dies the day after inspiring such frantic activity, lol.

General public like myself (a long way away east) get to hear about the headline events (through informative and engaging vid-clips like yours, thank you) which don't often even refer to the processes taking place underground. Finally my point 😄 you raise an interesting aspect in this edition: the Iceland igno-volcanic system (hot-plume & spreading tectonic plate boundary). Are those tasked with monitoring it able to 'see' all the magma movement / emplacement and gauge the 'pulse' or perhaps cadence as you very aptly put it? Fascinating work in an unique (and at least captivating) place on planet Earth 😊

It's definitely not coming to an end anytime soon. After each event magma chamber is growing, so it has more space to be filled. Which means uplift is smaller because magma is spreading more horizontally. But based on uplift alone it still fills at rate of around 5.5m3/s. But in reality almost half as around 4m3/s is going straight into dike most likely. So total inflow is the same as it was at the beginning which is around 10m3/s. Calculations based on uplift alone lack depth as it's only 1 dimension while magma chamber is 3D structure

Thanks for another informative update. I think you mentioned it before, but the density of the magma at depth is higher than the density of the lava erupted because the gases form all the bubbles at the surface. This means that the same mass of magma has a larger volume when it erupts at the surface.

You need to understand that solid plate over Svartsengi reservoir is not constant. It gets wider and heavier over time and needs a lot more pressure to lift it up. So far this plate has worked as pressure valve due to the high pressure of magma which drops when there is outflow. The lava from last eruption had consistence closer to Fagradalsfjall lava than Svartseni lava. Due to that we can imagine it was 2024 Fagradalfjall eruption what you was waiting for. It just hadn´t enough pressure to make it`s own way to surface and used Svartseni magma very high pressure to open the way. Next eruption from Svartsengi reservoir is estimated in september-october but it can be even more later because it needs even more pressure and if there will not be enough pressure then eruption may not happen at all.

Why do you ignore the first 6 days of data from the last eruption? In my opinion this has led to your top up rate of 3.5 cubic meters per second to be a massive underestimate. Estimates for eruption 5 was a chamber with 20 million cubic meters yet 45 million came out. That is an extra 1 million cubic meter per day direct from the mantle over 24 days, a top up rate of more like 10 cubic meters per second.

@Hliarmenn

When we see uplift while an eruption is ongoing, it means the influx is greater than the output of the eruption and when we see subsidence, the influx is less than the output. During the first 5 days, the output of the eruption was much greater than the influx into the chamber and thus we had subsidence The idea was that that when we saw GPS data turn from subsidence to uplift, we'd check what the output of the eruption was. When we did so, it was somewhere between 3-5 m3/s but it's hard to know the exact number as we can't have live measurements of the output. The reason the magma chamber had 20 mil m3 but the total output was 45 mil m3 has to do with density of magma at different depths. As magma gets closer to the surface and degasses, it loses density and expands. In the case of this eruption, it was by around 2x.

The GPS data for Svartsengi seems to me to have shown a small increase in its rate of increase over the last few days perhaps reflecting the end of the eruption. If it's real, then that means the calculations you made will be out but we can adjust accordingly.

It will be a shame if we get too long a break before the next eruption...we would be missing your updates and information on a frequent basis. And we would miss looking at data charts, and we would miss speculating, and we would miss our chat friends on various live streams, etc. etc., ...the list is long of so many things we would miss!

I'm curious as to how the scientists are able to predict that this eruption series will be over in late summer? This isn't meant as a criticism of their expertise; I'm just really curious as to how they can estimate something like that, so far into the future, with something so notoriously unpredictable. Is it calculated from the rate of decreased filling of the magma chamber? If so, I still wonder how they can know what exactly is happening with the original source of magma so deep in the crust? How would they know with such certainty that this source is no longer going to fill the magma chamber enough to cause more eruptions? I wish Þorvaldur Þórðarsson, Benedikt Ófeigsson, or another scientist would explain this reasoning in more detail. Regardless, I hope their prediction is correct and that the area is no longer under threat of more eruptions (at least for a few more centuries). I really admire the effort and persistence of the workers who didn't give up and kept fighting to protect all of the infrastructure they could. I think it also turned out to be a great learning experience as to what can be done for future eruptions on Reykjanes and elsewhere.

@Hliarmenn

8 күн бұрын

As you say, this field is highly unpredictable. Þorvaldur and other experts along with Geology Hub have all used the rate at which magma accumulation seems to be decreasing to make this prediction. It's thought that if the magma influx goes below 3 m3/s, it can no longer keep the conduit open and thus the event stops. All the estimates suggest the influx will drop below 3 m3/s sometime in late July, early August. As poppawolf said, data from earthquakes, tremors and GPS are used to create simulations that give us some idea of what's going on under there but we're still scratching our heads about what's deeper under the peninsula where this activity originates from. Will be exciting to see what discoveries our experts will make.

😀👍🤗

How big can the berms be built? It seems like an end to this phase is the only hope for the power plant. The government should really be thinking about long term back up options. Assuming that it's not buried, could the Blue Lagoon drill it's own hot water wells without the power plant?

@Hliarmenn

There's definitely a practical limit of how big our construction workers can make these barriers such as the time it would take. If these eruptions went in for years, the powerplant and the Blue Lagoon would most likely not survive. Ever since this event started, backup locations have been searched for and found but it takes years to implement them. Fortunately, it looks like this is coming to an end which would give our experts a long time to plan the future.
