Always appreciate your updates and your knowledge that you share on this channel! 💕🌋
Thanks Shawn. Questions: At around 16:40 - Do other 'hot spot' plumes curve to the West at depth? Is the rotation of the Earth influencing their curvature in the same general direction? Is this unique to the Iceland one, or is this the only one which has been studied in great detail?
Great update.
Thanks for going over the paper on the mantle plume!
Working the quakes back in time was fascinating! Thanks!
That paper was fascinating, and I am always excited when I feel like I actually understood something! You are such a great teacher!
It's interesting to see the locations of those earthquakes and the clear path from southwest to northeast. Hoping for the best outcome for Grindavik and the power plant. Thanks for the update.
I am learning so much about how our Earth works from watching it happen live in Iceland. Your updates are helping me understand what is going on. Thank you.
Thank you for another great update Shawn. I enjoyed your explanation of the paper on mantle plumes - the 3-d depiction brings the concept alive .
Thank you for the update. And congratulations on another achievement of 117K.
Thanks Shawn for the very interesting update. I learn a lot each time. Will keep watching the live cams. Thank you.
Agree and for what it's worth, at 01:42 he tells us which camera. Wondering why the increase is so slow and if the pressure thresholds have changed. I would guess threshold keeps going up a bit as the rock gets more plastic since the sill beneath Reykjanes since pathways up have been burned in around this area.
You've probably heard of the landslide across a river basin in Canada yesterday. Hoping you might consider covering that story from your unique point of view!? Thanks.
@shawnwillsey Awesome update Shawn! Can you cover the massive landslide and landslide dam forming a 10-kilometer-long lake in British Columbia? It's on the Chilcotin River upstream of the Fraser. The dam that formed is over 30 meters high and there's a potential for a catastrophic failure that could affect people over 300 kilometers downstream along the Fraser. Seems like it's not getting a lot of attention in the US and world news so any coverage would be helpful to raise awareness and provide good information for people.
Yes, I did see some news articles on this but am quite busy with the current load on my plate. I'll try to get more info on this if I can.
@@shawnwillsey Thanks for the reply and absolutely no worries Shawn! I know how busy you are with everything so please don't feel obligated if you can't. I only just learned about it this morning from some TH-cam coverage and was shocked by just how large the slide was and it's potential for downstream impacts.
Anyways, keep being awesome and thank you for all that you do!!! : )
I was following that. I don't know why there is so little coverage.
@reekoreeko1857 yeah it's kinda weird for such a big event, mostly just local coverage in Canada and some brief news vids on TH-cam.
Thank you so much for this really interesting update, Shawn. Specially the last part I find very fascinating.
Fascinating information. Metaphors (such as chimney plumes) anchor us and are useful in our understanding of things we can't fathom. New information sometimes demands new metaphors. This model may apply to other locations -- but perhaps not all. The key is technology that allows the collection of new data and new generations of scientists asking "what do these data tell us?"
Thanks Prof. Very interesting analysis of the mantle plume paper, very helpful diagrams, particularly the last one.
My interest is in physical geology and I was fascinated by the paper presented here. I'm definitely going to dig that one up. Good work, great episode.
Thanks for all the hard work on these videos!
Just a game chair TH-camr here, but just riffing on the paper cited: Would you tend to think the land mass of Greenland with the weight of its glaciers cause the tilt or shift to the east towards Iceland or another thought (haha) toward the tectonic zone. Perhaps the second idea is more plausible. Anyway thank you for this update. Happy weekend everyone.
Seems plausible to me. Greenland's crust is thick.
Another fantastic update. Thanks, Shawn.
Superb update, as usual. I'll be watching those webcams!
Thanks for the update! That paper on the mantle plume is fascinating! Interesting that the plume jogs over, much like the Svartsengi system's magma body is under the power plant yet erupts off to the east. I'd be curious to know whether they've done similar studies on other plumes, to see if other ones also have this sort of structure. I would also be interested to learn if plate tectonics would have any bearing on the direction of the tilt. Or if not that, then what would cause it to zigzag over in one direction or another. So many questions, so much to learn! :)
That last science letter, wow! Thank you!
Hello from Orlando! Thanks for all you and the team do
Thank you so much for this update and for taking the trouble to interpret the science paper. The findings are truly fascinating and it brings several questions to my mind too. The first being "has the mantle plume always been that shape and in that position?"
Brilliant, thanks again.
Thanks for the latest update shawn
Hi Shawn love your content and learning about the geology. This may be a little off topic but I was hoping you could talk about the land slid in BC Canada on the Chillcotin river that has created a natural damn and possibly how this could have happened or if there were warning signs.
Waiting is so nerve wrecking for the natives 😢
Thank you for the heads up.
👍👍👍Di..Cumbria
Iceland really is a beautiful disaster in slow motion.
Thank you Professor Willsey 🙏
Thanks, appreciate the updates.
The view of the plume is fascinating... I'd never seen a render of it like that.
Hey there Prof. Willsey, thanks for the lessons..❤👍
Thanks so much for the excellent update 😊 It’s like taking small mini classes. Hope you have a good day ☀️😊💐🌼🌟✨🌹🌸🪻
Fully detailed, comprehensive and professional update. Thankyou Shawn from NSW Australia 🇦🇺
always enjoy learning with you
The 3D plot of the magma under greenland/iceland was really instructive. Pretty amazing that it can be developed from the data.
You need to change that PIR sensor for a mmWave sensor, then your lights will not keep going off when you don't move much 😉
I believe he’s at his school office so might not have a choice in light sensor 😫🩷
Buddy must of us, myself included, are borderline r-worded. none of us know those acronyms lol
@@andrestein6022 Buddy, have you heard of Google? 😁
I kinda like it! 😅
I would have to see the lights sorted. Shawn waves are great. Anyway, all it needs is the time switch adjusted, no need to over complicate, lol.
Excellent update. Thanks for sharing the article with the great images of the mantle plume at various depths. Interesting to see the comparisons of the quake frequency over the past eruptive events too. That really shows that quakes are precursors of an eruption.
That paper on the mantle plume is so cool!
Thank you, Shawn. Excellent explanation and one that an amateur can comprehend.
The paper is very interesting-thank you for explaining the diagrams so clearly. I wonder if the plume has always (or at least many eons) been tilted or if movement of the plates has caused the shift at lower depths. What would keep this conduit intact? Why wouldn’t the plume rise to the surface more vertically from the base?
Excellent update as always, thank you Shawn! I also noticed the uptick in EQ, yes... It shouldn't be long now until something happens on the peninsula... ⏳
It's quite difficult to imagine how things are structured at depth, so the scientific paper on the Icelandic mantle plume is very interesting, thanks for walking us through it :) I still wonder how scientists can get data at such depths, though... Amazing!!
I have wondered if the Icelandic mantle plume had been modeled after re-reading about the magna chamber under Yellowstone. Thanks for the paper.
Really interesting paper Shawn, excellent analysis!
Hey @Shawn Willsey - it'd be really great if you could please put links to the sites you use (with the earthquake data plotted on maps and suchlike) in the video descriptions, please? That way we can keep up when you haven't posted for a couple days.
This Grindavik volcano has shown to have an extremely short fuse. I believe the big eruption before the last big eruption, this volcano offered no precursor earthquake "warning" before the fissure ingnited.
I expect the plume would be a very viscous material and just like a thick sludge, the top gets dragged along when the crust moves above it while the source stays fairly stationary.
Thank You soo much, You make this soo easy to understand even for me who knows nothing about this!!! 🤗👍
Thanks. Really interesting
Very interesting - thanks. I saw an earlier paper (in a Nature journal?) which also suggested that the active hotspot region had migrated E through time, from the older volcanic region in E Greenland towards Iceland. Presumably this is actually due to the crustal plates migrating over the deep mantle plume? Fascinating!
All the things we can learn about that which is beyond our physical ability see --it's astounding!
Will you be kicking out a video on the Land Slide in British Columbia?
No. I don’t have any info beyond what news is reporting.
❤🌋❤ Thank you for doing this. It is to bad they can not channel the flow out to the ocean.
Thanks again Shawn!
Interesting analysis of the mantle plume. Learned something new there, and I have a degree in geology.
I know as soon as I look away, this volcano will erupt.🌋
Thank you Shawn 😊 great information and breakdown 👍 👏 😊
wow that last was a kicker.. great find.. I am off to peruse that paper myself.. Well done son.. I appreciate and applaud your efforts.
Loved the mantle plume imagery. Thanks
Great little update, thanks Shawn. 👍🏼
Smoke from a chimney doesn't always go straight up either 😃
Hi Shawn, are you planning on doing a video on the large landslide currently damming a river in British Columbia (Chicolte?!). The situation looks very similar to a video you did about a river near the small town of Bliss .... The Canadian river has not burst past the blocking landslide yet.
Thanks for all your interesting videos you share with us.
From Australia 🌏
Sweet"white board" today! Geology finally has a MC Escher!!! (and I was amazed by the advent of the "Hobart"?) Lol
Awesome
Brilliant!
Great, thanks.
Your audio is fairly good, but during occasional volume spikes it sounds like you're getting slightly distorted. If you could decrease the microphone's gain slightly that would be helpful. Only slightly!!!
I noticed the uptick.
I love this professional and informative channel. Thank you for this. I hate all the 'Yellowstone is going to Blow' clickbait vids. This channel is a breath of fresh air.
Great update…. I wish we had x-ray vision…. What a sight it would be … watching and waiting thanks shawn
Is there a relationship or correlation between the shape this mantle plume and the shape of the tectonic plate boundaries?
As always a great video 😊
Thanks for all your excellent teaching, Shawn! I’m wondering whether the landslide on the Chilcotin River in British Columbia, Canada is of interest to you. Geology or hydrology?
Yes, I am watching this developing story.
@@shawnwillsey Great, keep an eye on the briefings on the GovernmentofBC TH-cam channel.
@@shawnwillsey Williams Lake First Nation TH-cam channel has a posted a helicopter flyover.
Do you have a video planned for the Chilcotin River landslide up in BC?
The plume is interesting. That makes me wonder, what should we think about the size and location of Iceland in relation to the plume. Would it make sense to consider Iceland already a pretty big volcanic island or would it make to sense to expect that the large plume would at some point grow it significantly? Especially given the hot areas to the south? Is the Reykjanes Ridge likely to rise significantly?
Hi from Terri from Waverly TN USA
The paper is US 2.95 to purchase for PDF download. Is it possible to make it more "accessible" for your viewers?
With that land under Svartzsengi constantly rising and falling, will that eventually weaken the rock and produce cracks?
Earthquakes of the type in those diagrams imply some rocked cracked.
Wouldn't that plume indicate that at 480km down it is moving faster than the upper layer, so the upper layer is getting left behind?
the paper is interesting. Is the plume's path suggestive of the subducting plate bending back on itself as it digs down?
What’s happening with kefla under the glacier by Vik ?
Katla? No signs of any significant activity lately.
@@shawnwillsey oh sorry got the spelling wrong , I know there were floods recently from the ice melt and I think I was told it was due to erupt. My family are near Selfoss
A senior icelandic scientist suspects the recent Katla outburst flood was indeed eruption related. He refers to recordings of low frequency seismic waves I believe (check my facts). This from Gylfi @ Just Icelandic.
I love your videos, thanks Shawn!
I've wondered a few times, do you think the weight of the erupted rocks on the surface can have an affect on the chances of an eruption, whether it could increase pressure to encourage an eruption or push down and help delay one?
Thanks.
So me being Faroese and seeing the mantle plume being 50 km below us, is there anyway the plume could find a new way to dig itself up below the Faroes or the area surrounding the Faroes?
The hot spot off the south coast at about 160 miles down is pretty sizable. One day that pluton with rise and make a little island there if not join the coast and extent the coastline. But that may be thousands of years in the future. A lot can happen in and around there in that time so who knows. Maybe Greenland and Iceland will be joined before its over.
How many seismographs do they actually have in the area? I'm guessing they're triangulating the location of quakes based on a number of seismographs and the intensity recorded at each sight?
I hope you make a video regarding the Chilcotin River landslide. I'd like to hear your opinion 😎👍 I enjoy your vids. Idaho I am
Incredible what science can shine light onto.
As ever, THANK YOU
Is correct to say, that Island is child of the ice on Greenland?
TY much!
Hello everyone
Hi Jeff I was wondering how you got the spelling of your first name. Mine because I was three pounds six Oz so my folks didn't think I'd use the name long
Shawn, isn't it time to get one of your students a special research credit to come into your office and take out the auto shut-off in your lite? You can be a responsible adult and shut off your lite when you leave the office.
NEVER fix the light sensor, it's great!
@@reekoreeko1857 obviously not during a video.....
The plume is not an elevator…it’s an escalator!
🤗 hello! Usual awesomeness here I see
Thanks shawn for your reasoned update. I dunno about anyone else, but isn't live cam minus quakes pointless and confusing for a casual viewer? Why was it introduced? I kinda understand what it means, but for me it's absolutely meaningless. Enyhoo, t minus three days...........
A plume under Iceland is essentially liquid, so no S waves can go through it. That is why it is blank under iceland. Greenland may have deep Craton rocks that are solid at depth like all over eastern Canada a few billion years old. That is like comparing hard rock with water. Completely different and geoogy and physics.
Thank you for another update , I found it very interesting
I'm waiting for Karin Sigloch to give us a 3D timelapse geophysical globe. I should've stayed in school.
What is "Daylight mountain time".... I'm guessing something American...? Any chance you can just give time in UTC which is what the world works to...?
Iceland uses UTC.
Aloha from Makaha.....earthquakes are increasing.....it won't be long now....
One would think that very few things on a rotating planet would be straight. Most things would tend to have some sort of deflection.
wow it shows how complexed the hot spot is, thank you Shawn (Rock On)
