Iceland Volcano Eruption Update; Cyclical Bursts of Activity Occur
ฝัง
- เผยแพร่เมื่อ 30 พ.ค. 2024
- In Iceland, a volcanic eruption is still going strong on its 27th day. Lava has built up to as much as 75 feet in thick areas, but something else interesting has recently occurred. Lava has recently started erupting in a fairly predictable increasing and decreasing cycle almost like that seen in a geyser. This video will discuss the ongoing eruption, and why this cyclical activity is occurring.

The overflow of the crater was mesmerizing, I was watching it live when it happened, I have never seen that in other eruptions in iceland.
The 2022 eruption wants to know your location
@@lolvondgf Nar was pretty similar.
@@ThatOpalGuytag you are it
@@lolvondgfthose mass flood of the 2022 eruption were mesmerising, huge floods of lava, it looked almost unreal.
Yep but keep in mind that IMO is confirming that Svartsengi's shallow storage chamber is inflating at higher rate, so when the eruption ends, the inflation will shoot up as current inflation rate is around 4mm per day while 3mm are feeding the eruption. When that stops, it'll turn to 7mm per day, so it won't take long for storage chamber to refill completely and go another magma run in 20-30 days at most. Check GPS data and you'll see what I mean.
Bingo
Interesting. These eruptions will be studied for a very long time.
How much time will humans have?
Who says we have a long time , ⌛️ it's been a long time already! 💝
So hypnotic to watch. I'd be there constantly if I lived anywhere close just to see it.
I’d love some more updates on the Fernandina’s eruption. It’s now actively creating new land for that island due to lava reaching the ocean and that is just as fascinating as the Reykanes eruption
This has been so wild. Obviously, we have more instantaneous news than even 10 years ago, so we can follow these fascinating geological events. These effusive eruptions are beautiful, mesmerizing, and exciting. I feel so much for those who have had to leave their homes.
Love the possible explanation to the varying intensity.
Why should I watch these cyclical eruptions in Iceland? I get to watch them in my kids at home all the time.
That's bad parenting. Why don't you teach the kids some self control, discipline and relaxation techniques?
Danke für das Update
Thanks as always! I do wonder what will happen to the Reykjanes volcanic system next...
The next few weeks should be interesting, with the current eruption winding down while there is a new weak inflationary signal in the Svartsengi area. I can't help but wonder if after this eruption ends if we will see a return to the cyclic/periodic eruptive cycle we saw previously.
Thanks for all of your hard work man!
For the geyser like cycles involving a cavity, do you think this cavity is like the one left empty at Thrihnukagigur? After all, that one is part of the Brennisteinsfjoll volcanic system, and should have behaved relatively similar to Reykjanes during its eruptions. It seems like it would be a great way to study how cyclical volcano activity works, considering that both an active and an extinct, empty, and accessible version exist.
Please do a video on the central Atlantic magmatic province
the twentyfirst day three in a row is still pretty impressive.
i concur with Your conclusions !:-)
Fagradallsfjall 2021 eruption had this cyclical behavior during most of the eruption with activity completely ceasing between those cycles.
This eruption should have ended again nearly 2 weeks ago according to experts as well and yet it is still going.
SWEET GURRRRRL
How is the lava effusion rate measured? And how accurate is the measurement?
It's measured through a variety of means, though the estimated volume of the lava flow is certainly one. The quoted uncertainty is 3.6 +/- 0.7 m^3/s (or between 2.9 and 4.3, likely on the higher end considering its ongoing activity)
I was watching another video on this eruption, and the person who was covering the volcano said that the main sill/magma chamber that's been feeding these eruptions was starting to fill and cause uplift. If that is true, and this eruption doesnt end by the time the main chamber rushes into the fault that the eruption is on, would it cause the current eruption to go on for longer? Or like with Mauna Loa/Kilauea, would the inflation cause the vents to pinch closed and prevent an eruption until the next drainage?
If memory serves (I'm out of date by a week or so due to a family vacation to see the total solar eclipse) there has been a very low level amount of inflation for a while though it had been leveling off at some point so it is quite probable that inflation may be still ongoing. How this might impact the eruption itself depends a large deal on what is occurring within the system for example are minerals in the magma precipitating out along the conduit causing it to get gradually clogged? If so its a question of whether the pressure building in the magma sill complex below is able to dislodge some of that material. On the other hand as you noted the inflation itself could be constricting the channels too in which case the influx of magma may be starving off the system's own conduit leading to a feedback loop which shuts down activity fairly quickly once a certain threshold is reached. Really there are many possibilities depending on what is going on in the volcanic plumbing down there. Volcanoes are complicated.
@@Dragrath1 At beginning of april inflation greatly increased in speed compared to first 2 weeks of eruption averaging to 0.2cm a day and is continuing at this rate since
What is going on with the main chamber that has been filling the dyke? Is it refilling, and at what rate? Is there a possibility of it recharging the ongoing eruption before it seals up?
It varies, but overall, the magma chamber is refilling. However, it is noticeably slower than the 5(ish) cubic meters per second during the periods in between the previous eruptions. I have not seen the Iceland meteorological office put out an exact rate at which it is refilling though.
just wondering aloud here, but what would happen if you flew a helicopter over the lava pool and dropped in a large amount of sand or clay into the lava, and what the composition would change into as it flowed out? would the sand turn the lava into some sort of more glass like material, like obsidian? it would be a fun experiment (if it has not already been done in the past) to put different materials in the lava and see how it actually changed the materials flowing out. maybe we could make some sort of new super material for construction, and maybe it would be a big waste of time and money. if anyone has any info on this it would be interesting to hear back from you.
omg ... this isn't new... where were you during the two previous eruption?
I imagine through out the history of the world that many of these magma chamber bubbles have existed and some remained empty eventually. Has there ever been evidence that these have eventually collapsed over time or have been eroded into?

Congratulations...
hi everyone, can we visit the volcano to view this incredible spectacle?
No.
So can you say it's like acting like a piston?
The eruption seems to pick up at night, is that a coincidence?
I wonder what kind of influence the absence of sunlight would have on the supporting magma flow underneath the surface.
On the other hand, you are able to notice a glowing lava flow better when it is dark outside than during the daytime.
Perhaps this makes people think that there are more or more intense volcanic eruptions during nighttime.
👋🏻👴🏼
pretty much at this point icelandic magma is probably a type of deadly nocturnal liquid basalt based lifeform and that seeks out blindly any kind of prey lol (im joking mind)
No. Day/Night cycle has NO effect on volcanism.
Is this AI narrated?
No it is real person.
@rantothon73 No it is real person.
No it is his real voice. It comes across that way because he is autistic - he explains this, shows his face and gives his real first name (Tim) at the start of his recent livestream from Iceland.
But did it not at least occur to you from the voice that he might be autistic - I would have thought that was common knowledge these days? And do you not think it is a bit childish to make fun of someone's voice - and a great deal worse than childish to knowingly poke fun at an autistic person?
By the way this site is actually about volcanoes not voices, so you might have noticed that yet again Tim has produced an excellent video giving an awful lot of professional-standard information in understandable form in just five minutes. Do either of you have the ability to produce any sort of even half-decent video yourselves?
This is guessing at best good night
