There's a need to keep that coffee coming whilst Shawn Willsey is in Iceland. So I will try to make that happen. You can warm it over the lava if you have a those hands and face protected from the astounding heat! Take care there 👍🌋 ⛰️ loved the volcanic maps you put up. Epic Data
Maybe this is a guy question for a video:
Is a magma chamber able to get larger or increase it's maximum pressure by making ground and rock above and near it more ductile? How quickly does the material around the magma chamber heat up and how far does the heat gradient extend? How do the ground properties change? I imagine that after many earthquakes, with increasing fracturing maybe, and temperature increase the properties of the rock and soil above the chamber change, like getting more ductile or changing stress tolerance.
Judging from the amount of uplift over Svartsengi between recent episodes of this eruption, it seems that there will need to be at least another 30 mm of uplift before either the next fissure opens, the remaining spatter cone enlarges, or both. Based upon that approximation, let's watch what happens between the 12th and 17th of May..
Hi Shawn, quick question: As all of the volcanic gases are colourless, why is there white smoke? I know H2O vapour becomes white visible steam as it condenses in the air, but as 'visible steam', it usually dissipates into the atmosphere; the smoke doesn't. Any idea why?
Ah, I see that you covered that aspect through someone else's calculations, Shawn. Thanks for the summary.
I was going through my foto-library lately. My mother and her husband sadly lost her house in November 2021 due to the eruption in La Palma, and memories came back since of course I was watching this very closely. So I went back to some videos of that eruption and man, had I almost forgotten how HELL BROKE LOOSE THERE in some of these vents and lava-avalanches! Compared to this these cones look like a kindergarten - and still they are huge, dangerous and the whole situation very serious for a lot of people. Thx for another great update!
I can't believe I've been following this system 6 months now
Utah had a 4.3 yesterday and it is still Swarming EQ
Never have I thought I’d see a cone within a cone 😮 your explanation makes total sense 🙏🏼
Thank you Amanda-Jo and Shawn. I think Bruce has been communing with Pele to try and fix the eruption for your holiday Shawn.
You are amazing. Also thanks to Amanda-Jo.
Still brewing🙄so glad I'm in albany western Australia thanks prof for your continuing updates wendy
Icelandic free spirit of an eruption. Comes and goes as it pleases.
Thank you for the update Prof: Willsey ✌️
Thanks to Shawn, Amanda-Jo, and Bruce for another informative update. Looks like Shawn may have an interesting visit coming up if Bruce’s projection is correct.
Thank you for the update! Thanks also to Bruce for a great job with the data analysis!
Thanks, Shawn, for the update. Traveler in the Whole World had a really good video yesterday showing the new cone inside the old one.
Shawn, I would like to add appreciation to others for your dedication and hard work to geology education . The " just the facts and data" opens your eyes to what formidable ladies Mother Earth and Mother Nature are. your moderators Mandi J and Susan ( if I leave out others pls forgive)make an awesome education team ! Combine that with Gylfi's magnificent drone footage WOW! lastly my admiration to the people of Iceland for thier bravery and dignity as lives are upended and dramatically changed!💌
Thanks for all of your hard work man!
Thank you. Great details from you and all contributors.
Thank you, team! 💗It is important to have your reports to make sense of all this happening in Iceland.Otherwise iit is really difficult to discern and dogest all by ourselves!thank you , Shawn and Amanda Jo for sharing your enthusiasm and amazing , wise, lightly presented abundance of information and knowledge as days go by we get closer to next Wild Earth's activity that otherwise might seem incomprehensible for the majority of us , the admirers of nature , who doesnt have the certain credits of academical knowledge as you!
Thank you for digesting and giving all this information easy and addaptated to our untrained ears 😂( so to say)!
Thanks again for sharing and your updates.
Thanks for the update @shawnwillsey. I have a good friend who is a Geology professor for BSU and told her about your youtube channel and how you're following the volcanic activity in Iceland and also your other geologic videos.
I’m in Iceland right now. It is amazing! Leaving the day you arrive. Can’t wait to see your video on. To explain what I’m seeing!!
Thanks Shawn. Traveller had an interesting drone flight video yesterday showing the small spatter cone within the main cone. It would be great if the next event takes place whilst you are in Iceland!!!
Just Islandic has a wonderful view on this, too.
I appreciate your video and all the great information. Thanks for posting! 😊
I hope you have fun in Iceland!
Have a great day!
Thanks Prof. Willsey for your constant updates on the current situation in Iceland and on Hawaii + all the Random Roadcut videos and overall great geology content! Since I started following you I became increasingly interested in the currently increasing amount of volcanic activity in many regions in the world that were quite in the last 30 to 40 years. Maybe you could cover them in ore or more (small mini series 😊) videos in the future. Indonesia and Italy ( Vesuv and Campi flegrei) beeing the obvious but also volcanos in Kamchatka Peninsula and South America show rising quake activity, steam plumes and developing domes which have the potential of eruptions of VEI 3-4 and on a very bad day maybe a VEI 6 ( maybe not happening for the next couple hundred years or so , but some of them were quiet the last 500). This may also be an interesting topic for a collab with an colleague fellow youtuber. Maybe do a poll if others would be interested?
Also big thanks to Amanda-Jo and all the others for collecting, processing and publishing data and information and helping gathering and spreading knowledge 👍.
Great timing. 😊
Couldn’t have said it better. Just finished work and sitting down with a coffee 🎉
Thanks for another interesting update. Greatly appreciate your time to keep us all up to date. Have a wonderful interview tomorrow. Can’t wait to see it. Thank you.
Saw it on the replay. Saw the 3+ by the volcano
I loved all those maps on land and under the sea. Fascinating.
Thank you.
Di……Cumbria.
Thanks as always for your time, Shawn.
Thanks!
Thanks Prof, and thanks for putting the offshore earthquakes into perspective
Thanks for that. I had got a bit behind!
I started being aware and interested in vulcanism and iceland in particular during the 2020? eruption there (the 'first'). watching iceland explorer and just marveling. since then I've explored the older erutions on hawaii (something estates). your videos have helped add context and illuminated what is happening and has happened. thank you.
I hope you have a fabulous trip and that the volcano gods turn on a show for you.
I look forward to your updates.
As always a very informative video. So appreciate everything you share with us. How exciting to be heading to Iceland. I shall look forward to those videos. Thank you Shawn. Safe travels. Gillian
Much appreciated
Hi Shawn and every one from New York
Thanks so much 🙂
Thank you Shawn for this whole series (and your field trip videos too!) Wanted to mention that Oliver Strimpel just posted a new interview on Geology Bites that totally relates! - he's interviewing geologist Bob White on his detailed seismic study of exactly how magma moved through the crust in leading to an eruption in Iceland in 2014. Search for Geology bites, Bob White on How Magma Moves Through the Crust. (visuals are posted below the recording, including a spectacular animation of the data.)
Thank you for the update!
Thank you -
Great update there are no questions cos no one knows… we are so lucky to see this… sad for Grindavik but a wonderful earth lesson
Thank you,
Fascinating. Thank you.
Hello
Thank you for this update 😊
Thank you and Amanda Jo, Bruce and all of your actively working team. What is the significance of the depth of an earthquake?
Thank you so much @shawnwillsey for another clear and informative update! And thanks as always to @MandieJo for helping you :) Also, nice job with the SENG gps data over time Bruce, thanks for sharing! Once again, we'll have to wait and see how things go but you might be in Iceland when the next event actually happens, Shawn. Fingers crossed that you can access the site if so... 🤞🤞
Once again, a very professional and highly informative update based on an extensive scientific knowledge. Makes such a change from some of the over-excited, animated, inaccurate and non-sensical splurge that is put out there on some other channels. Thanks again for the work you put in to this Shawn 👍👍
Thank you, Professor Shawn, so much interesting information.
And thank you Amanda Jo, you are in our thoughts and prayers every day.
Thank you Shawn, i have exhausted all my chat about these chapters in Iceland...I know nothing, get back to doing my chores and spring cleaning lol...Going to just watch your updates and leave it at that. 😊
I see that the Krisuvik M2.7 quake has now been revised up to M3.29 (that's a fair jump - more than 7x the energy!) and there have been a couple of aftershocks - one at M2.7 and a couple around M1.5 - about 3 hours later.
What's up with Surtsey lately? Last eruption I know of was in June of 1967 as I was off to college, ultimately studying GeoScience.
20:35 PDT Cone still glowing.
Wouldn't that be SO COOL to be there for the next event ! I hope that for you ! 😊😂
quite mind blowing looking at the biggest volcano cones in the world to this one and thinking the amount of magma that was rejected to create them. Thank you again Shawn for the update. Have a great vacation in Iceland. Do you ever take any rocks back to the evergreen building from iceland
In terms of the biggest volcanic cones it is almost certainly linked to Flood basalts and other Large Igneous Provinces as nothing can compare to the insanity in scale everything else volcanic is basically negligible in scope. Volcanic cones don't last very long though since they are generally lose piles of unstable ejected material.
In terms of more contemporary examples did any of the fissure eruptions near the hot spot core form cones? I know Laki and Eldgjá were produced when these spreading intervals coincided with the fissure/fault system where the primary magma chambers of Grímsvötn and Katla respectively have formed in essence they seem to be equivalent of episodic outburst floods of magma.
At 17-43 Iceland time there was a 3.29 up North Northeast of Krýsuvík, might be tectonic!
Yep. I addressed this at the end when first one popped up.
A Hornito! That's wild!❤❤❤
Aloha from Makaha......
Aloha from Puna
Aloha.
Eldey too apparently, Nesting Sanctuary to a rare bird, is worth watching, despite people maybe not being impressed, by the magnitude of the quakes, is an indication the Peninsula is waking, which will affect Rekyavik sadly.
I wonder in time, how much Iceland will be affected. Clearly if the Power Plant is lost, it will have real inpact on the Country.
Your knowledge is so valuable, thank you, although this is an unpredictable ongoing Event, surprising many Experts.
I just hope the Tourists invading the area, causing more problems for the local Police, Mayor & Workers, are not mislead, into underestimating the dangers of the current Eruption area 🤔
I love how the seismic data shows the fault and its rough location going through Iceland :D
I thought your discussion of how graphic representations of data can possibly be misleading (unless the reader is aware of the scale) a really good point to emphasize. Maybe mention that in future episodes. I love the many maps you expertly toggle in and out of, illustrating very well your comments. I don’t miss an episode. Your work is amazing, Shawn!
Thank you kindly.
Great work Shawn and team, can you explain if the depth data from the area under the ocean is calculated from the ocean floor and not sea level as it is on land? Many thanks
I always look forward to your videos coming out.
I have a question. I find it odd that all these latest eruptions have started as a long fissure. It can't be that the lava simultaneously finds its way to the surface everywhere along a several kilometre stretch, but rather that 2 plates have move apart in an earthquake. Can you comment on this and what you think is going on?
@shawnwillsey please clarify what you mean by "gasses". We don't see most gasses, as they tend to be transparent. What I think we are seeing are particulates, smoke. Right? It would be good to make this subject more specific and precise, don't you think?
Looking at the map at 12:36, I'm curious about the volcanic zones on the Snæffelsnes Peninsula. All the others are aligned with the MAR, but these are almost perpendicular to the ridge trend, and from the map legend, they also have a different chemistry from most of the other volcanic zones. Any suggestions about what's going on there? They seem like outliers. Thanks for all the great updates!
Shawn, I will be in Iceland at the same time you are. Interested in getting some good photographs of something volcanic.
Hi Shawn. Surly if all this uplift is occurring, and every eruption means the ground is getting more elastic therfore the ground is dropping less, wouldn't that mean the sub storage area for the lava is also increasing in the amount of lava it stores?.
Where do the folks building the new berm get the material from?
Hello everyone.
Good long time to get the wall done😁
Hi Shawn, hope Amanda Jones is doing OK in Iceand, the earthquake she mentioned to you has got a lot worse and there have been any since your today's live talk
What about the Magnitude 3 quake even further off the coast or the Magnitude 4 quake halfway between Iceland and Norway?
It's going to be interesting to see what happens next. I think the next eruption might be out to sea.
more aftershocks to the 2.7 quake, just checked at 10:31 pm local Iceland time
Thanks for the info shawn. Nice and concise. I cannot figure out how it manages to keep on keeping on with such low pressure. It's not like toothpaste being squeezed out of a tube. Can anyone enlighten me?
Gases in magma.
Thanks shawn. Incredible stuff going on there. Have a great time when you go and hoping there will be lots for you to see. Happy travels.
😂 another great update thanks shawn
As I recall you were waiting with your cam for the present eruption.....No warning of EQ . How did you know 🤔
I was wondering if the pressure of lava filling the void could be shutting off the flow to the spatter cone? If that vent pipe happened to cross the top of the void and be slowly crushed and choked shut?
Anyway that uplift could pop by the balloon analogy?
I'm thinking that with the vent slowing down. The magma is working south towards the town underground. Seems like it is time for another location again.
Curiosity is driving everyone crazy. The whole Just Wait and See deal😂
After watching this since febr 2021. Eldey always had a big swarm just before eruptions so might be a precurser for something new ???
Correlation does not equal causation. 😉
As you look at that volcanic system map ( 2:20 ) you can see that the capitol is located in a rather stupid place, but then I guess, that like Grindavik, the volcanic activity is also the thing that created the good harbors that the communities grew around.
I wonderr how much lava is still flowing out under the surface and what's gonna happen with the ongoing land uplift.
Wouldn't an offshore erruption cause a steam plume that potentially could be challenging for air traffic? Or is the distance from the site to the airport enough to negate these issues?
Very low chance of this.
Most commentators have focused on the total amount of magma building up, whereas you have mentioned the RELATIVE different starting points of the uplift. Interesting different emphasis....probably explains why what is there has not yet erupted!
Is that Mtn a Resurgent Dome? It's been said it's an ancient volcano?
Gutn just showed a tiny spot left of magma in Crater.... almost over.....for now?
😊
The next eruption will in my estimation be near or even further SW of the most southerly SW Grindavik intrusion; the route for the magma run may demand little earthquake indication; being an established route already manifested most of the shakes. I doubt the berms success is as robust as hoped for; reality will vindicate in due course.
The offshore quakes look a tad scary but as you said the visual may be worse than the actual quake thatmay be less tha. M3
I just discovererd this channel and I am so glad that I did!! 🤗👍 It is soo good and interesting and soo well presented information about the erruption in Island but now I am learning a lot of other interesting things about geologi all around the world thanks to professor Shawns videos!!Thank You soo much!! 🤗👍🌋🏔️ Cattis
I got in trouble for saying "let me show you my 'spatter-cone'".
Like before, lots of possibilities each with an associated, ever-changing, probability. The big ? is where is the choke point located? The last one started with an estimated 1000 cu M per sec, and I don't see this cone supporting that type of flow for more than 30 seconds, just saying.
Where and how is the heat generated to produce the magma deep down ? PLEASE How come drilling for oil and gas does not cause an output ?
My guess is a form of friction. As our planet earth is girating about it's axis with the earth surface moving about 1000kms/hour eastwards whilst it orbits the sun at goodness knows how many tens of thousands of miles per hour. All as the moon, stars and other planets influencing the earth and earths surface cause movement. A trillion tons of ocean rises and falls exerting varying pressures. So unseen is a lot of heat generation. A bit like a bee heat ball where a group of bees all contribute by flapping their wings generating heat. The earth's crust sheilds the core from some heat loss. So it builds up inside. Vocanic eruptions are heat regulators allowing the core to self cool.
You can discover friction by rubbing you hand on you arm. Movement results in heat (energy).
Was it the Uplift?
Hi Shawn How i identify tectonic quakes to volcanic quakes is by depth of the quake EG quakes 4 - 8 Kmls deep = Tectonic quakes 3 -1 Klms depth = volcanic quakes My thoughts as a UA-cam geologist lol
Good on ya, lava-glowingly make a monolith and stop threatening the habitated countryside.
Why not build existing bearm higher? Thankyou
Traveller posted a drone video today see over view of cone...
Trench.
I wonder what people think of when you say magma. What do people think it is, and what it looks like. I think I know but it may not be what everyone else thinks it is, or what I think it is, looks like. Does it look like lava/ Maybe a slurry of hot mud? I think it looks like smoke if you could see it. What does pressurized gas look like. Whats a tank of gas look like inside the tank or cylinder. Nothing really or maybe smokey of misty to clear. Subsurface appearance may look like swiss cheese with the holes being pressurized gas. And the pockets gather to make bigger pockets and they are squeezed in any given direction so when a crack opens to the surface the gas, or magma, is forced out at super high speed and being a volitile gas, it ignites when mixed with the air above ground. Thats my sort of understanding of what magma is. I could be wrong but this is what seems to be what is occuring subsurface.
