08:00 Small addendum: S waves are also called shear waves. And the reason they only travel through solid rock is because you can't shear a liquid. They can get transformed into P-waves (which are similiar/equivalent to sound or pressure waves) while coming across that medium tho.
@@Hliarmenn Having taken a look, it is an interesting observation, but imo more work needs to be done to confirm this. If you look at this open access paper about the seismicity preceding the 2021 eruption (DOI: 10.1016/j.epsl.2022.117685, just copy it into google scholar), then you can see that the EQ in Krisuvík are also at a similiar depth back then. Further, the spreading of the EQ in this system in the blog post as well as in the paper show a WSW - ENE direction which agrees well with the plate boundary in the peninsula. See Fig. 7b in the publication for the various tectonic movements that can be observed on the peninusla. It is still interesting, that the Fagradalsjall area is still capable of producing deeper earthquakes compared to the other systems. I suspect it could be due to no eruption having occured there for so long relative to it's eastern and western neighbour. The deeper crust could still be more rigid and brittle, while the stress transfer from plate movement and magmatic intrusions in Svartsengi/Krisuvík can only occur in the upper part of the reykjanes crust. That is purely my own speculation tho.
Thanks for the explanation about how scientists determine where the magma is located underground. Easy to understand about the s and p waves. Excellent info.
Excellent! I do love the clear and unpatronising help [for non-Icelanders] with keyword/placename pronunciation. I love the pacing of the voiceover - perfectly in the Goldilocks zone! I also find the amount and choice of content just enough to be both manageable & engaging,so we can join the dots to make sense of happenings and the visuals/footage [🎉for *old eruption* label flash!] Thank you! Top quality stuff! ❤
Watching near Toronto, Canada. I visited Iceland in 2017 and fell in love with your beautiful country. Ive been so worried about the eruption and the displacement of all the people of Grindavik. This update is so well done and clear. Thanks for the information and for filling a void not covered by network news.
🌱🌏💚 KiaOra. Hellooooo Hlidarmenn. Serious & major events to report today. I hope the missing man is located asap & rescue workers + work crew can get the heck away from that area!!! Appreciate your phonetic enunciation of Icelandic names & words, it's very helpful for Icelandic language beginners. I think you'd be a great Icelandic language tutor! 🙂
Ayy, Amelia! Yeah, it would definitely allow everyone to breathe more easily. Glad to know the pronunciation parts are turning out well, gotta make sure y'all can flex on people when the next major eruption occurs in Iceland with the pronunciations😉
I hope they find him as well, but things are getting slim with each passing hour. Not only because it decreases the chance of finding him alive if he didn't fall into water or got burried, but also because it increases the chance of an eruption. Uplift has passed the critical point for an eruption days ago, so it could erupt at any moment.
One of the cardinal rules of working around trenches or areas with a collapsed risk is to have a safety monitor monitoring the worker/s from a safe distance from the work area who can call in rescue personnel and provide directions to them in case of a cave in. It is also appropriate to use remote control compactors instead of allowing people to work in trenches that are susceptible to collapse, and to use a crane with a safety tether attached to the people working if there is a fall risk.
So interesting to listen to well informed comments and explanations. Thank you. I do hope that the man is found , but I doubt that he will be still alive. Trust you will all stay safe if everything does erupt.
Seems like Earth's ticking time "blast".. a massive pimple/cyst building up to burst on the Earth's crust. Such magnificent landscape. I have a deeper appreciation for people having Iceland on their bucket list. Parts of the video reminds me of the film set used for Stars Wars: Rogue One.
Yeah, it definitely takes a lot of hard work for the Earth to produce these breathtaking landscapes. It's always fun when the film industry comes here for "other planet scenes".
Times are changing and I'm afraid not for the better. This is only the beginning of a new eruption cycle. Prayers for all of those in harms way,God Bless!!!❤😊
Reykjanes Peninsula has been very active for the last 2.5 years, making it an EXTREMELY tempting attraction for geothermal energy and geological tourism. My condolences in regards to the fallen man in Grindavik 🙏. Hopefully, rescue is successful.
Wow, sounds like there’s a whole lot going on. I hope everybody’s safe out there. I feel bad about that worker falling down the crack. Sounds like they should be using the safety line.
Just found your channel. Very informative, and it added to other information I already had. I just subscribed, as so much is going on in Iceland. I had no idea how interesting Iceland is. Thanks for the info and saying hi from North Queensland, Australia 😊
Hope you are doing well, thanks for the update! Always interesting to think about what's going on under the shin of the planet. I really hope they find the guy who fell down the shaft! Stay safe everyone. God Bless Iceland.
‘ goldilocks ‘ zone … that’s a technical term , right ? ha ha. Thanks for a beautiful presentation that tells me also about Icelandic observers of the formation of new earth under their feet! ❤😅Jenn Frykman Portland OR , USA
The news report about the fissure talks about a “bridge” … which I’m guessing is referring to a ladder?? Or something else? Anyway I hope they find out where the man is.
Thanks for explaining about the S waves and how scientists can tell they are potentially being blocked by magma. If the S waves data subsequently shows up in the data, can scientists discern magma movement and possibly direction? Is this S wave detection block frequent or infrequent? Thanks for taking the time to explain this.
It could be possible to see magma movement and direction if a lot of earthquakes are striking. Then it could be possible to track where the S-waves stop coming from and link that to magma moving there. I'm not sure if they're just used to detect static magma reservoirs or if they're also used for magma movement as I'm not an expert myself. But definitely sounds possible, just need a lot of earthquakes 😁
It is important to add that these geophysical measurements are all proxies. We have currently no way to directly measure or locate undergrund structures (except for drilling). So we base our understanding of subsurface structures on the characteristics of the rocks and how they interact with various forces we can measure. It is then up to us to correctly interprete the data we receive. it doesn't tell it on its own! But we are really getting good at this. Using seismics to model underground structures and relying on natural earthquakes, you need to lay out a relay of geophones and record lots of earthquakes over a long time (better data quality) over your area of interest. Think of it as lines of seismometers overlapping each other. Then you can conduct seismic tomography and get a 2D or 3D image of subsurface structures. I don't know if this was done here. But as you can see, that this is unlikely to help detect magma movement, and more stationary bodies. Especially basaltic magma can rise very quickly in a matter of hours or days from many km down. There are of course other geophysical methods you can use to confirm your findings, but all of them might have their unique up or downsides to this particular case. And most of them take time to carry out, especially if you want to cover an area this huge.
Thank you for keeping us updated!! I know you live on a volcanic island, but there seems to be at least 2 on the go? Do you think they'll find the man? I pray that they do🙏. Thank you for all of your updates ❤
Yeah, two volcanoes at once is definitely a lot for Iceland. I'm sure they'll find him as they're working really hard with good equipment, the weather is also clearing up which should help a lot. I'll update y'all as soon as we get more news🙏
All the landscape photos are shot with my drone and require a road trip 😁 Unfortunately my drone is down at the moment so I'm not able to film anything new😔
Damn, listening to information like this makes me wonder if I would want to know all this if I lived on top of a volcanic island lol. This has to be kinda nerve wrecking if it's happening right under you or relatively close by.
It does feel pretty surreal but I'm fortunate enough to be pretty far from areas that are effected by eruptions. People of Grindavík, on the other hand, definitely feel different as an eruption can basically happen within their town. I to think that must be stressful.
Seems the Government of Iceland has not kept the monitoring of it's constantly changing landscape up to date. Where are the wells monitoring live areas and dormant ones Not influenced by the challenging weather? Too many questions and just a shrug of the shoulders.
Enoch returned in 2017 and the Tribulations are almost. The earth is about to see things as never before. 2nd Enoch 20:3 is The Most High Creator Aravat. He arrives in less than a year for judgment day. Seek truth in our creator instead of the scientists, please.
End of times person right here. How many times have people like you said "the end is near, world is ending at such and such date, get ready" and in the end, nothing happened. As for scientists, they're not involved with religion, unless you maybe have one who studies it, otherwise, no connection between them. Most scientists work in whatever fields they studied for.
Good morning from Valencia/ España. The Icelandic landscapes hypnotized. I am very attentive to everything that happens out there. Thank you very much for the information you provide. I have subscribed to your channel.
