Well done Shawn. Your channel has become a great conduit for citizen science, bringing lots of people with expertise from diverse fields together (like Bruce) and applying that expertise to geology. Modern scientific disciplines have become too complex for any one individual to be a polymath, but by reaching out across boundaries to people with an interest in geology, it creates a hive mind that functions in a similar way. This is really important because it has often been polymathic thinking that has delivered the greatest leaps forward in scientific understanding and identifying new ways of collecting and analysing data. This is so exciting 😄
My mind just boggles at the idea that we can gather and analyze all this information in real-time. My 18yo self in Geo 101 back in 1982 would never have imagined this possibility.
It's always exciting when you tell us that you have more graphs from Bruce! And I'm looking forward to your work with Isaak tomorrow - thank you to all of you.
Having both you and Isak on a collab is wonderful; can't wait! I find it interesting that the Feb 8 earthquakes were focused in the general area where the August eruption occurred.
Thanks for the update, awesome as always. And thanks again to Bruce Garner for the fantastic analysis with his charts. So excited for your collab with Isak!!
Excellent update! We really are a team ! Thanks Bruce for the beautiful 3D earthquake maps. I was having trouble visualizing 2Km, 5 km, etc. And thanks to the person who sent the map where the escarpment is visible.
Thanks for the update Shawn, its always great to see new graphs from Bruce and get your explanation of what's happening. Looking forward to your collaboration with Isak tomorrow.
Thanks for the update Shawn. Also, big shout out to Bruce for the 3-D earthquake graphics. Those are really great! I'm looking forward to having you do some collaboration with Isak when he's flying. You guys are gonna be great together. 👍 😊
Thank you Shawn for your continuing updates! And wow, Bruce, great job!! Thank you both so much 👍🏻 I'm currently in Iceland, experiencing everything first hand and I'm really greatful to getting all your analysis and explanations. Love it loads.
Hi Willsey That was really interesting. Thanks for the update. It's going to be a joyful experience with Isak. He is doing a really good job. We all have something to look forward to!
Great update Thank you Shawn, and thanks to Bruce for sharing his earthquake data chart and the 3D model of the earthquakes was very cool to see I'm very much looking forward to seeing you and Isak doing a collaboration tomorrow, oh and thanks for sharing the link for the new map of Iceland made me very happy.
Hey Shawn, thanks for taking the time this Sunday to do another update, excellent content as always :) What a great job by Bruce, indeed! I especially like his 3D earthquake videos: they really help me visualize what's going on in the subsurface, so: thanks for sharing, Bruce :) Very excited for tomorrow's livestream and your collab with Isak, it's gonna be so cool :)))
Thanks forctelling at what time the update is. I always missed the last ones because I was at work or occupied... tomorrow I'll be watching right from the beginning
I just happened to be using my mouse to bring up another window as you started using your mouse on your screenshare, and I got so confused! Duelling mouse pointers! 🤣
Jam packed information, thank you to everyone who contributes to Shawn's updates. Team work! Really excited for the collab with Isak. Maybe he can fly over to that escarpment and valley area?
23:53 "You can see it flowed right across these other ones that look the same." At first glance, they look the same. But the detailed topographic map shows that these other ones have the lower elevations to the northwest. Unlike the wall where the lava stopped flowing to the northwest and tried to find a way around it, the others are kinda like downstairs to the northwest and the lava has no problems to spread to the northwest anymore. Thank you for your always wonderful videos and have a nice day. 👋🏻👴🏼
Thank you Shawn. So great you’re getting many connections with awesome mapping. Seeing the pics of how the ground looks is amazing knowing the escarpment’s were lava beds. Fascinating. Thank you. Looking forward to tomorrow’s drone flight and lessons. Have a good one.
Enjoyed the analysis showing that the depletion level after the most recent event was lower than the bottom of the previous one. Not sure I would have noted that. Great analysis! Thanks.
Bruce`s map is very revealing. It shows that Grindavik is right in line with the current events of activity so, it looks like it could be in the cards for a vent to form just about what would be the middle of the town. And, the activity that close to the powerplant is too close for any comfort.
What, if any, is the cumulative effect of almost 10 months of earthquakes happening in such a confined area? Has the bedrock become so cracked that it’s becoming easier for magma to find an outlet? It seems each eruption has had less and less seismic activity leading to it, and a much less marked increased of activity immediately before eruptions occur. For instance this most recent eruption had practically no warning. I had lain down for a nap and noticed a few clustered quakes occurring, but didn’t think it noteworthy. 20 minutes later my wife was excitedly waking me up telling me the eruption had begun.
Hi Shawn. Thank you for your continuing education on geology. It's amazing that we can now watch and discuss volcanoes in realtime, and your collaborations add an extra dimension. Would you do an update on Campi Flegrei? It's getting hard to distinguish between media frenzy and actual facts...
Thanks to Bruce Garner for the detailed analysis and 3-d views of the seismicity. The last view showed how the early earthquakes in the northeast were deeper and only on August 22, 2024 did the rocks break apart at shallow levels and the dike reach the surface with the spectacular eruption that day.
Serious praise to Bruce for these really excellent diagrams, which must have required quite a bit of work manipulating large datasets. I would like to have walked through them more slowly, particularly the 4D plots, in order to visualise better what the magma has been doing in the different eruptions.
One thing I noticed in Bruce's charts is that when plotting the inflationary/deflationary behavior for those different GPS stations is that there appears to be a longer term shift in elevations suggesting that the intrusive magma body in question has likely moved where the melt is getting preferentially stored in the subsurface. That seems like it might be worth looking into.
Those three-dimensional plots that Bruce sent really gave a fantastic view of the entire dyke that has formed under the surface. It makes me appreciate the old exposed formations we see on Earth today and how large they can be.
I'm not a Geologist, so this may be completely off, but both this and the last eruption were accompanied by sizeable drops in elevation and continued drop (+ earthquakes) for a while during the eruption. It appears (to me) that both eruptions caused significant expansion of the pathways available for magma to reach the surface.
Re: at about 23:00 when you started talking about the escarpment, there are several similar features visible in the area. You mentioned the graben - are there accompanying horsts?
Would the horsts would be the walls he was talking about on each side of the graben? The wall that stopped the lava flow. He also called it an escarpment and a fault scarp.
So we have this cycle of zit fills up, zit pops. Lather Rinse repeat. Determination of when a particular eruption ends is re;atively straightforwards. But is there good experience/knowledge on how to determine of this cycle of lather, rinse, repeat has ended? Is lack of inflation the sole paramete? And how long of "no inflation" before geologists will annouce that the cycle has been stopped it is likely some other reservoir will fill up and pop elsewhere? Is there any information/indication that the reservoir under Svartsengi might have a lather,rinse,repeat cycle that lasts years? or is there expectation this will stop soon?
3D Earth quake excellent Great Bruce Perhaps qualify three different sizes to aid scaling And you are not far from making a small quick video say about a few secs per day
Graben NE of Litla Skogfell where lava stops along a line: On maps shadows are thrown from a position where the sun never stands (at least in middle latitudes like France or Germany) so that you can recognize that the SE side of the graben is bright (lit) and the NW ist dark (shadow).
? Sveng seems to be slower to resume uplift than other stations, could the storage area be moving closer to the past eruption areas as EQs have been continuously breaking rocks in that rae for a while nor?
Thanks for your continued educational coverage on this event. I wonder if anyone can enlighten me as to why, with land rise and magma filling upvetc there is no seismic activity associated with it? Thanks in advance.
There is space for the magma to move into now that magma storage zone has been partially emptied. Quakes will pick up when it is full and pressurized and magma is forced to widen cracks and space.
Ohh. Thank you shawn for your time. I will try to get my head around why there is no seismicity while all that ground lifts up. Awesome stuff. Thanks again for your information and those who contribute so you can keep us well informed. All the best :)
The center of greatest uplift before each eruption is a zone 3 kilometers west of Grindavik/3 kilometers southwest of Blue Lagoon. Yet earthquakes don't seem to be associated with this uplift and the lava never exits near it. What is the explanation for the uplift area southwest of Blue Lagoon? If magma is pushing it up, then why are earthquakes and surface fractures not associated with it?

Yo,
Wow!
Thanks.
Thanks for all the information - and yet another link for my collection. (the Örnefnasjá one, I so far had the Umbrotasvæðið version)
Looking forward to the collaboration 😊
Thanks for the update. These are always so interesting! So, if there aren't any surprises, there should be another eruption around the holidays?
Thanks!
Many thanks.

Theres a lot of Pelée's hair falling between keyflavik and outskirts of reykjavik

Aloha from Makaha
Spatter cone, Bruce. Otherwise, brilliant work. Thanks Bruce (and Shawn, of course).
Hello from Orlando
How high is the spatter cone. Hard to judge for me. Thank you as always.😊
This eruption is starting to resemble my acid reflux......years of roiling and boiling and occasionally overflow.
It would be interesting to see an animation of that 3D plot showing the earthquakes over time.
Shawn,
Should we be worried about the Katla Volcano??
Cheers,
Rik Spector
When he clicked the last dot on the first 3D it was not all after intrusion, it says pre-intrusion. So he first showed after and then before.
So we have this cycle of zit fills up, zit pops. Lather Rinse repeat. Determination of when a particular eruption ends is re;atively straightforwards. But is there good experience/knowledge on how to determine of this cycle of lather, rinse, repeat has ended? Is lack of inflation the sole paramete? And how long of "no inflation" before geologists will annouce that the cycle has been stopped it is likely some other reservoir will fill up and pop elsewhere?
Is there any information/indication that the reservoir under Svartsengi might have a lather,rinse,repeat cycle that lasts years? or is there expectation this will stop soon?
3D Earth quake excellent
Great Bruce
Perhaps qualify three different sizes to aid scaling
And you are not far from making a small quick video say about a few secs per day
Hi Shawn, have you seen the very recent report that Hellas is about to become more interesting?
No real surprise it's continuing the pulling away of the two plates

Hello fromBrownsPoint, Washington . ❓can a jökulhlaup get highly-viscous like lahars.
Can it become cement-like❓
