Glad you are asking some of these baffling magma-budget questions. Clearly the volcanic plumbing is not yet well understood. Hopefully lab analyses of the new lava will help.

I agree 👍. We're learning a lot from these eruptions. Uplift has been the best precursor both for when an eruption will happen, and the volume of lava. I'd like to know the total uplift for the entire peninsula, and how much it's changed these last few years.

I want to note that the dates I mentioned represent the latest possible cases for each outlined in scenario. If any of those were to be true, the eruption would likely end earlier.

not only that lava broke through barrier north to the grindavik, but the lava fountains are now higher. 4 seconds were the highest pieces falling, which is quite significant increase from 2.5-3 secs

Looking at the tuyas scattered around the area we can see that this system is capable of events producing quite a lot of lava. I wonder how big a tuya these current eruptions would have made if they were piled up. Probably not as big as Mt. Thorbjorn (yet), but a good sized hill, perhaps. The tuyas have to be at least 8000 years ago (when the ice sheet left Iceland), but what's 8000 years in geology?

Thanks for all of your hard work man!

Thanks as always! The question of where the extra magma that is currently sustaining the eruption is a *very* interesting one. I do want to follow new information on this.

I really appreciate these bite-size information updates.

In one of the last videos from Shawn wilson, a user sent him a 3D visualization of the earthquakes that preceded the eruption, in those you could see 2 deep clusters one under the power plant and one north-east converging towards the fissure, I think that additional magma has something to do with that NE cluster (that also had been going on for sometime before the eruption).

I think it is a secondary source. But i could be wrong

What about the concept that since the lava is free to run from the chamber, the back pressure to the mantle is lower, so more lava can enter into the chamber?

Given the geology of Iceland, on two diverging tectonic plates, Grindavik will likely remain uninhabited, perhaps buried, along with many other surrounding areas. Visualize what Iceland will look like in ten thousand years, a much larger landmass consisting of lava flows upon lava flows as tectonic plates continuously separate. Those flows will be weathered down by rain, ice, and snowfall resulting in erosion, the land mass ever changing.

It certainly looks like it is sustaining quite well.

Thanks!

Since there are some signals for a prolonged effusive vent eruption. Could we get a comparison of data to the transition from thr Mauna Ulu to Pu'u'O'o vent eruptions? I know the eruptive heights are not similar (as the vent length of O'o, was much shorter at the start and therefore was much higher). Any other Long single effusive vent similarities to Piton de la Fornaise or Mauna Loa?

As a small country with limited resources, Iceland should develop a Dept of Volcanoes. Guided tours, flight discounts, etc.

It depends on what you would want that government department to do. Iceland is hardly a country characterised by limited resources seeing as it places amongst the top 10 wealthiest nations worldwide in terms of GDP/capita (which is in line with the performance of other Nordic countries). Furthermore, the private tourism market in Iceland is well developed, in fact it is the largest export of the country. I don’t think government involvement beyond current levels would meaningfully add to the experience of foreign visitors hoping to catch a glimpse of a volcanic eruption.

Interesting. 1 question about aomething u had said in another video about lava taking moths and even years to cool depending on thickness, is th3 fi3lds in Hawaii from the massive fisher eruotion are those cooled yet or are they still hot in the deeper layers

It looks like a portion of the southern tongue (on the other side of the berm from the greenhouse) has started advancing again, aided by some steep topography to keep it from piling up on itself. Drone footage: kzread.info/dash/bejne/hqCbqs6LnrG5g7Q.html

Is it possible that the incoming rate has now changed? Perhaps it’s >10cu m/s.

I wonder when Fagrafalsfjall will erupt again. It could be fairly soon considering it follows a 6 month to 1 year cycle roughly. I mean it could be longer or shorter than that. 2 simultaneous eruptions within a few miles of each other would be quite the sight. Something reminiscent of the early earth.

Is there any way to get a picture of the magma channels underground? Such as radar or magnetic imaging, etc? Seems like this would be a highly studied area with the powerplant so close....

@dralord1307

uhm, Ground Penetrating Radar requires you walk on top of the ground to see under it. So not a good idea where the eruption is at. Mostly earthquakes are used for looking for large "objects" under ground. Since you can time the waves and tell approx where something is because the speed of the wave changes due to density differences.

How is it possible none ofthe flows have expanded in 48 hours? Where is it all going?!

Yeah!

Sometimes a volcanic mountain gets covered with snow and the weight of the snow and ice limits the eruption by countering with its weight the upward pressure. Is this why most of Iceland's volcanic activity occurs on land instead of where the weight of the water pushes down, offshore? Rift zones on Hawaii and Iceland seem to always occur on land.

I think you should think the opposite way. Frequent eruptions in an offshore area creates land, so the land happens to be where eruptions are.

Yes, that could happen, lots of volcanoes in Iceland, including with explosive eruptions, so this excess lava may be linked to remote activity, ie under another site in Iceland.

I keep seeing reports that magma is bypassing the reservoir. That's a bunch of absolute nonsense. But as long as there is inflation and an eruption. It only makes sense that the reservoir and any attached sills are pressurizing. A second eruption at another location continues to be possible imo.

If the eruptive volume is between 10 and 20 cubic meters per second, wouldn't the inflow by the magma chamber be roughly the same or higher? As in between 10 and 20 cubic meters per second or more? If 10 to 20 cubic meters erupt at the surface then shouldn't as much enter the magma chamber to replace the magma erupting at the surface? I mean, that 4.85 cubic meters entering the magma chamber doesn't seem enough to replace that at the surface. Let's say 10 cubic meters are erupting out of the magma chamber, but 4.85 cubic meters enter the chamber, that's a difference of 5.15 cubic meters. Where's the missing 5.15 cubic meters of magma? If 10 cubic meters of magma leave then 19 cubic meters of magma should replace that, right? Now, I'm proposing that the inflow might actually be higher than the 4.85 cubic meters. From what I've seen the uplift zone covers a large part around the Svartsengi area. It's possible that the magma chamber might actually be much larger than previously thought, thus the inflow rate is much higher, at least double, than the 4.85 cubic meters suggested.

Why do you volcanologists keep trying to predict eruptions with such certainty when you can't even categorically explain what's going on down below?

I can not help but think our volcanologists here in Iceland a bit shit after seeing this video. You explained what is happening and how it is happening in 4 minutes, while they have spent years giving meaningless answers like ”It seems like it’s abating” or “ looks like a quick one”. They have access to all the same data since they are collecting it, they are just do a dogshit job of communicating it.

Just because somebody sounds confident in drawing conclusions doesn't mean that those conclusions are correct. People are biased to distrust those who communicate less certainty, but those people are often being more truthful about what is actually known and what is guesswork. I agree that showing data and stuff is nice, but it really annoys me that "we don't know"; "there''s no real way to predict" and the like are not respected more. This isn't weather forecasting, where people are working off centuries of widespread daily data collection in order to say things like "there's a 30 percent chance of snow tomorrow". These are rare events.
