You are correct that it isn't the Fagradalsfyll area being affected here, which is to the east of this region. But it is also not the Reykjanes 'volcano' either imo after watching videos on this subject for weeks. This magma intrusion is in the Svartsengi volcanic field. There is no particular volcano associated with this magma intrusion which should be obvious given how much it has been moving around. The Reykjanes volcanic field is further to the west of where the uplift and earthquakes are occuring.

😅😂. Well that is sure rich in sarcasm?!

In the first place a lava flow is hardly a river of rocks when the whole lava flow is molten rock! And second it isn't about stopping a river of rocks, but rather to divert that lava flow which has been done before. In a barrier created against a lava flow in the Fagradalsfyll eruption in 2021'helped to slow a lava flow.

It would probably amount to tearing the roads on both sides and fixing the underlying pipelines then repaving which would inevitably result in a low sloped road in that area.

Wow. Now there's a good resource to consider. Just take some Hollywood movie with exaggerated effects and see how a barrier made a difference against a lava flow in that case. 🤔

@jaewok5G You seem to think you know better than the people of Iceland who are trained to deal with the threat posed by volcanic eruptions so why don't you fly over there and tell them how it's done. Then come back and write a long rambling story about how you saved the country of Iceland! How mother will probably say, "Oh that's nice dear"!! 😅😂

That's just the way life is sometimes. We can make preparations for a potential eruption to occur in one place, but then it occurs in another. At this point this is their best option when in this uncertain situation and the best they can do is gamble that this is the right one.

Duh! So what happened to preparing for the eventuality in case the eruption happens that could threaten the power plant??
1
This has nothing to do with trying to conquer nature! It is only about diverting a potential lava flow that might threaten the Svartsengi power plant.
1
Isn't it obvious?? The idea is build a barrier to prevent lava from encroaching toward the power plant! You do understand that lava would erupt from underground right. One it erupts it flows in the easiest direction down hill.

@reson8 It isn't about stopping the lava flow, but diverting it.

@reson8 There are vast quantities of basalt available in Iceland which is primarily the rock used to build barriers as they are doing around Blue Lagoon and the power plant. Basalt can withstand the heat from the lava because the lava would immediately start to cool when making contact. And a thick barrier of several meters would be effective against a lava flow primarily in diverting the flow. It depends of course which way a lava flow approaches a barrier. Even a direct impact by lava in a barrier would cause the lava to spread out laterally at first. At least slowing the lava flow down would allow authorities time to raise a barrier level. Iceland has more experience handling lava flows than just about any other country.
1
@reson8 As I stated earlier the lava would begin to cool as soon as it makes contact with the basalt in the barrier. And further even if it heats up basalt rocks on the exterior of the barrier, it is much too thick to directly compromised by the lava. If the lava flow is massive enough and approaches the barrier straight on it could eventually go over which is the bigger concern anyway. But at least the barrier would slow down the lave flow.

Look at the history of Iceland. Lava flows have rarely threatened towns and cities in Iceland. Besides the last time there was an eruption in this part of Iceland was almost 800 years ago. There is no old volcano that Grindavik is built on, only old lava flows at least hundreds of years old.
1
Yes the lava composition which is basalt doesn't allow for the formation of enough ash to form Pyroclastic flows. None occured in any of the previous Fagradalsfyll eruptions 2021 - this year.
1
What happens when the hole is filled up?? Besides this part of Iceland like most of Iceland is covered with previous lava flows that are rock hard and many meters thick!!

 @kylekingsman300 😂😅🤣. That's the weakest and most irrelevant comment ever besides being blatantly false! Clean up your own life instead of projecting your delusions!
1
Actually it did work well against an encroaching lava flow in the Fagradalsfyll eruption in 2021.
1
Gee, I wonder if the people of Iceland ever thought of that!? Hmmm that's a tough one! 🙄

@aleuttrel2260 The town of Grindavik is not on a volcano. The town was established decades ago on old lava flows like the rest of Iceland. And it was only in the last month that a magma intrusion appeared, but not near Grindavik at first. Initially the magma intrusion started about ten miles to the north near the Blue Lagoon and the power plant before eventually moving south. This intrusion under the town caused uplift, earthquakes and fissures to open up which meant a possible eruption could occur there. The longer it is delayed now not erupting the less likely it is to happen. There now I fixed your misunderstanding for you. Course that was the nutshell version. The more detailed version would be 1000 words or more.

@aleuttrel2260 Are you making up your definition of what a volcano is because you are wrong. A magma intrusion does not count as an eruption since it has not erupted. Though I understand you are making some effort to save face it won't work. Below is the definition of a volcano from the Oxford Dictionary. You're welcome!! "A mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust".
1
@aleuttrel2260 . Then read my definition of what a volcano is again because what happened in Grindavik is not what the Oxford definition is for what a volcano is. There is no MOUND of erupted lava for example anywhere in Grindavik nor a mound of any kind. The uplift in Grindavik is from a magma intrusion NOT a volcanic eruption!! And the town of Grindavik is on a old lava flow, but that of course is not a volcano!
