Shawn, you should make this a "pinned" comment so it stays at the top of the list so everyone sees it first. Just a thought and how others seem to do this on their channels.
@@markpashia7067 Thanks for the reminder. Done.
Hi Shawn do you think the Volcano will Erupt under the Blue Lagoon. Can you ask Professor Pordarson.
Another home run, Shawn! Professor Þórðarson is an amazing and straightforward resource, an excellent match to your passion for sharing your knowledge in this fascinating field. And I agree with @crabapple1974's mention of HUMILITY. In this historical time where opinions overtly (and often destructively) dominate the dispensation of news, humility is the signature of those striving for honest and objective analysis. I have seen both you and Dr. Þórðarson say things like "not everyone agrees with me" or "we're just not certain about this, so the truth may be different". For my own part, it's the recognition that only through questioning our own assumptions can good science become better! Keep up the great work. You are providing a valuable and welcome service to us!
Well said. We are fortunate to be in the presence of such great scientists
Or to put it another way, true scientists don't say "the science is settled"!
The science is never "settled" - there is always something more to discover or correct or study.
It was an awesome moment when you asked how to differentiate between EQs and he said "you tell me". The best educators are humble and honest with what they know and don't know. Also something I would have assumed science knew but it shows just how far we have to go in understanding the planet and its complexities.
I've enjoyed these videos so much partly because I loved geology and I've hiked all over Arizona and partly because I'm going to Iceland in September!!
If we knew what we were doing it wouldn't be research.
It was a privilege to listen in on this fascinating discussion between two professors of geology. Thank you Professor
Þorvaldur Þórðarson for providing information and insights into the situation in Iceland. Thank you Professor Willsey for arranging this excellent interview.
Absolutely brilliant! Thank you both.
Shawn, you have a real knack for asking the right sort of questions to make complex ideas accessible. And thanks to Professor Þorvaldur Þórðarson for his clear and informative answers 😊
What a great interview! Thank you both for taking the time for this scientific discussion. May volcanologists and geologists, and all the learned experts, be listened to by the stakeholders and critical decision-makers to support communities pro-actively.
I'd rather say stateholders, being states part of our (for the time being) only home. I enjoyed greatly two scientists.
A really good interview what made it so good was listening to two professionals with positive humility with one another, neither interrupting and speaking over the other. Made it a really interesting and productive interview for us novices to learn from on many levels. An opportunity to see - this is how its done. Looking forward to the next one. Thank you both gentlemen.
Thank you so much both to Profs Willsey and Þórðarson for taking time out of your busy days to do this. It is truly a privilege to be a fly on the wall for this conversation. That idea of incorporating lava flow simulations to inform municipal zoning / planning is an idea I hadn't heard of but it makes so much sense. I hope it gains traction going forward.
Fantastic interview, it's like listening to the pros talk shop. Big thanks to Professors Þórðarson and Willsey.
Fascinating interview. It's great to listen as two passionate educators share their knowledge. Thanks for setting this up so we can all learn.
Absolutely wonderful to hear my two most trusted Iceland geology and volcanology resources together in conversation with each other. Very informative!
This was fascinating and better yet, being able to Listen to the Professor speak and actually understanding his explanations is a true indication of how good you have been at helping us understand the science of what s happened so far !
Thanks so much Shawn !
Prof Þórðarson had to be the most interesting & informative you've had on your show. Thanks to you both.
This is the first time I’ve seen the Professors name spelled with a Þ instead of a TH. 🤗 This was so cool, thank you both! ❤❤❤❤
Really interesting interview and I got a lot better understanding of the complexities and unknowns. Good questions from the interviewer and nuanced humble answers. Greetings from Sweden.
You're a kindred spirit, especially your mention of "humble answers". It's something desperately needed in these times.
Prof Porvaldur has saved so many lives in Iceland with his knowledge. He is a wonderful man. Loved this interview.
Thank you for bringing us this interview. It was very informative!
"You tell me". Love it. Excellent questions Shawn. Thank you Professor Þórðarson.
A very interesting exchange. Thanks to both of you for doing this.
One thing occurred to me whilst listening to the prof, which you might consider for a future interview: seismologists are able to use the different velocities of S and P waves in different rocks to reconstruct the wavefront through the earth from a seismic event and then work out where there is magma (even thousands of miles away from the hypocentre). I believe the Yellowstone magma chamber was mapped using signals from earthquakes around the world. I've even watched oil prospectors use heavy vibrating trucks to pump energy locally into the earth to construct 3D maps of the sub-surface terrain. From 50m away, their vibrations felt similar to those from magnitude 4 quakes that were several kilometres away.
Given how many seismic events we've seen in Iceland, why do we not have a clearer idea of where the magma reservoirs are, their shape, and their size? Is it related to the wavelengths being too large to resolve smaller reserves, or is it that the area is so complex, with all the faults and fissures that the signals have become too chaotic to be usable?
A couple of geologists seriously nerding out... We listeners are the wallpaper....
Thank you so much for sharing this. Allowing the lay-person to witness these conversations between professionals makes us all smarter.
Thank you. What a breath of fresh air you are. I really appreciate observing the Professor in a more relaxed, scientific frame. So much more useful for the world! Well done! Keep it up!
Awesome interview Shawn! Been watching for months now and I love how informative, educational and enlightening you have made geology, volcanism, etc so accessible and interesting. Keep up the good work!
This chat / interview was great. Thank you, and I learnt something - hadn’t really thought of Iceland as a high volcano plateau - but of course it is.
I learned something too. I didnt realize there is a deep cap under the blue lagoon as well. Its obvious when you think of it though, those geothermal wells would be exploding if they were not insulated somehow.
A privilege to be witnessing this conversation. I enjoyed the volcanic forensics, and appreciated the insights into the strategic vision - how to leverage the spectacle to educate and inform future choices - some common ground for both of you there.
One of the most interesting interviews I have heard! Thank you, Shawn, for inviting this interesting man to your program.
Þorvaldur is an amazing scientist, straightforward, knowledgeable and informative. I have learned so much while listening to your conversation - will definitely repeat the pleasure and listen again! ❤
Thanks, Shawn, for this terrifically insightful interview with Professor Þorvaldur Þórðarson - I learnt an awful lot. We're so fortunate to have educators like you and Professor Þorvaldur Þórðarson who are not just willing to share their valuable time but also their in-depth knowledge. Be sure to pass on our thanks to him! :)
Great interview! So glad that you did this. And many thanks to Professor Þórðarson!
What a fascinating interview! Thank you to both of you for making this happen and sharing with your viewers!
As a mechanical engineer trying to understand plate tectonics, volcanism, and earthquakes it seems like you need a finite element model of the crust to understand the stress state field in the crust around Iceland. It seems rock has many temperature dependant properties. Cold rock is elastic in relation to strain energy causing earthquakes, exhibits brittle fracture at faults, plastic behavior with "warm" rock under pressure, and then buoyancy, viscosity for mixed gas/solid phase for "hot" magma that acts as a hydraulic fluid. How do you measure the stress state of insitu rock? I dream of small robots that could detail the distribution of rock, faults and thermal distribution around this area. Thousands of boreholes to understand the region
Thank you and professor Þorvaldur Þórðarson for bring us this informative interview.
What a fantastic opportunity for two professionals to talk. You both had your professional faces on and were obviously satisfied with your conversations. Well done, sirs.
Thanks Shawn! So great to hear two thoughtful experts discuss these events that have captivated all of us.
Thank you Prof. Willsey and Prof. Porvaldur. What a pleasure this chat, so interesting and informative. Goes to show the importance of science, in this case the Volcanologist / Geologist.
Congratulations on your first interview. Very well done and very informative. Looking forward to learning more. Thank you both for taking the time to do this.
Great interview. I really hope you get to have him on again. I really appreciate how both of you are so accessible to us non-geologists. Thanks to you both!!
This was outstanding!! Keep it up!! I am learning massive amounts about a subject I never expected to study. Your approach to teaching makes the subject accessible to mere mortals. Thank you.
The dream interview we’ve been waiting for!
Fantastic interview! Really glad you were able to connect and thanks to Professor Þórðarson for his insights!
Takk takk Fryir !
til ykkar beggja. Hlakka til að heyra meira.
I knew you would ask the right questions. It was a great interview and l look forward to you doing this again not just with Dr. Thordarson but other scientists, seismologists or those who monitor these areas. I'm glad the channel is growing. I hope you're enjoying the ride.
Shawn, brother, I just feel compelled to leave a comment, which is rare for me although I spend my days writing and composing. I am such a big fan. I have spent a lifetime out exploring Nature. With so many questions about how in the world these wonders of Nature were created. Watching your channel has advanced and accelerated my understanding and comprehension of the forces of our planet literally light years away from where my years of my humble observations during my solitude had gotten me. Thank you for answering so many of my questions. I'm very grateful. You are a Master educator, Godspeed. Peace
Many thanks for your kind words.
Fabulous interview by Shawn and the Prof. The dreams CZcams are made of 😎👍
Have been looking forward to this!!
Ditto
Huge thanks to both of you, that was interesting, fascinating and educational. Two lovely gentlemen that treated each other with respect and integrity. I will have to save for that book on Iceland 😊.
What an absolute treat! I've watched an interview with this professor before and really enjoyed him, so getting both of y'all in one go was just awesome! Both of you are just real down to earth (pun intended) people with the ability to traverse the intricacies of this topic without causing a mental overload on our parts.
I’ve learned so much from this channel! Thanks Shawn!
Fantastic discussion, Thank you Professors
I think that's the best interview with Prof. Þorvaldur Þórðarson that I've seen so far.
He really got to explain things in depth.
So many of the media interviews were short and asking basic questions, some of them impossible to answer concisely.
Not His fault but down to the nature of news clips I guess.
This one has been great.
Thank you both. 👍
All since I was a kid I've been really fascinated by volcanoes and have had some curiosity towards them, but my curiosity never really came close to my other interests of music and motorsport, which I have spent a lot of my childhood and into adulthood learning and even getting my education in. But interestingly something has changed now that I've become older and I think the eruptions at Fagradallsfjall spiked my curiosity for it again. I've started watching videos from Just Icelandic and later on I found you, and I must say that your videos has been really great for me to get an understanding the basics of geology and volcanism. I find myself looking at rocks, parts of mountains and landscapes back home here in Norway and I look at it all in such a different way than I used to do.
I find this interview really great and so fascinating, because you both are able to explain things in such an easy way that makes even me as a complete novice to understand what you guys are talking about. And I find it so much fun to watch you two, as knowledgable as you two are, just talking about the things that you love and even learning from eachother as you go. It seems like you two could've continued talking about these subjects for hours, and I would've still listened 😂
I hope more of these interviews are coming, because I find them very interesting and they make for great learning experiences. The more I watch, the more curious I get and the deeper I want to look into all of this. I am a nerd and you know how nerds are. If you first realize you're nerdy about something, you might aswell just go down the rabbit hole and explore it all!
Thank you, Dr. Willsey and Dr. Þórðarson for the informative lecture.
Thank you so much for this great interview! Lots of objective info, humble and honest answers, it's such a cool way to learn, I love that. Many thanks to prof. Þorvaldur Þórðarson! Looking forward to the next one!
This is great! Thanks to both of you!
Really interesting to hear Þorvaldur being interviewed by someone who can ask the right questions! Thank you!
This is great, thank you professors.
Thank you both for this very informative conversation! I learned a lot again.
Marvelous interview! Just fascinating. Thanks!
Great interview Shawn. Really enjoyed watching it. Thank you both for doing it. Looking forward to seeing another interview in the future.
Thank you, very informative. You have wormed your way into my head. I can’t drive to town without looking closely at the road cuts on the way!😂😂
You have arrived. Xanadu.
Amazing discussion! Thank you for sharing your knowledge and experience.
Looking forward to more collabs and chats like these in the future
An analogy of lava moving into a shallow storage area becoming increasingly pressurized until it exceeds the tensile strength of the crust, is like boiling a pot of water with the lid on. The lid begins to shake and rattle until the internal pressure lifts the lid off and the water spills out.
Exactly what I’d been thinking too, with the episodic rattling of the ‘lid’ set to continue until either ‘the gas’ is turned off (inflow ceases, perhaps as the good Professors said because of a separate seismic episode on the fault boundaries) or there is such a huge ejection of lava that the ‘pan’ cannot refill before the inflow reduces or ceases
Thank you both for a really interesting and illuminating discussion.
Gday. Thank you both for taking the time to give us these insights. Great info. Cheers
Ohh this was so informative..thank you both .. your knowledge is so important part of our times 🤝
Fantastic interview! A couple of more shows and I’ll be a full fledged amateur rather than just a team member!🤗
Fabulous discussion gentlemen. Thank you so much - it was a privilege to listen and learn from 2 experts … 😁
A great talk. Enjoyed every moment of it. Thanks both of you!
Thank you. Brilliant talk so Interesting
Excellent interview! It is really nice to see you also learning along with us. You are a great example of a scientist - questioning, always learning, continually collaborating with others to find answers.
Absolutely fantastic being able to hear this candid conversation about Icelandic volcanism and where we are now. How 'bout that ash and steam cloud we saw on this channel as the lava flow was waning. Wowee. Gotta say...great for tourism besides the northern lights.
Very informative Thank you Gentlemen
Thank you both so much, was waiting and looking forward to this interview today 🤩 Hope to see you chating again soon 🥰
Thanks for supporting geology education. I appreciate it.
Fascinating listening to thess two who actually know what they're talking about, and if they don't know, they say so. But still they give their best educated opinion. Thank you both!
That was awesome! I learned a lot. Thanks for reaching out to the professor and having him on your channel. Hope to see more of these in the future.
Amazing, i hope for another discussion with the 2 of you, very educational
Those 40 odd minutes went by really quickly. It was really good to hear him, I had in fact no idea his English would be so good. Thanks for this rare opportunity.
I've been following your videos from Scotland for the last few months and have very much enjoyed the content. Tonight's show with Prof from Iceland was excellent, if you can do this say monthly it would add an important local component to your already excellent analysis of the ongoing situation. Thanks for your excellent channel, keep up the good work, Alex.
This is awesome! Great information from the two of you! Thanks! Never stop learning!
Oh! This is wonderful! Thank you, Shawn
Thanks so much for doing this interview, and also for teaching us so much geology over these past few months so that we can understand the concepts the two of you discussed.
That was great. Thank you both!
Thank you Shawn. A fascinating interview. Rarely are the 'right' questions asked and without a leading agenda. You asked them all with an open mind. Thank you. Incredible to to be able to share in such a discussion between two very like minded scientists and field specialists, both of whom are more focused on the data rather than conjecture, clearly separating fact from their own interpretation. Thank you.
That chat always had to happen, and it didn't disappoint. Two great guys talking real
These are my kind of scientists…the ones who KNOW they do not know everything and aren’t ashamed to say so! Thoroughly enjoyed this! Thanks to both!
Fascinating. Learned a lot about the system on the peninsula. Thank you to Professor Þórðarson. Really enjoyed the discussion on infrastructure planning and mitigation too!
Wow, this was a really cool discussion. I really like Professor Þórðarson's clear and matter-of-fact style of explaining things. I learned a lot here. Especially the part near the end about his study and the misconceptions regarding how water affects eruptive behavior, that was really interesting.
Thank you Shawn and Þorvaldur for this interview. Incredibly fascinating. Having governments do mitigation above response and recovery is a tough one but sure would be beneficial.
Fascinating conversation. Thank you both.
Danke Schön Willsey
Brilliant interview Shawn. That was so incredibly interesting. I really enjoyed that.
Hey Shawn - Great interview!! You seemed very well prepared, great questions, and not nervous at all :) Geology is an interesting topic, for sure! Thanks for sharing your knowledge with us. Enjoy your weekend!
Glad you enjoyed it! Thanks for your kind words.
So much info in such a short time. I'll need to watch this more than once. Thank you.
Thank you both for an informative discussion and shedding common sense on the situation
Thank you for a very educational and interesting interview. It is a long time (30 years) since I studied plate tectonics and geology as part of my Environmental Studies Bachelor of Science degree here in the UK. I have always had a love of Iceland and hope to get back there soon. The events and eruptions have awakened my interest in this field of science again and your informative channel and today’s interview have aided in helping people understand the processes at work. Looking forward to seeing more. Thank you again.
This was brilliant, thanks so much
Thank you so much for that fantastic interview. really enjoyed it. so much great information i learned some new things sat here with a big smile thank you.
Thank you both, it was very interesting; I learned a lot from this professional interaction. :-)
Great to hear his point of view on these events. Would love to see more of this kind of interviews.Maybe he can join a live stream of you so we can ask questions to you both or maybe let him look at questions you weren't sure of the answer from previous streams?
Fascinating and informative! Thank you both sooo much!
