For us who need visuals to understand, this was excellent. I thank you again as always. Looking through old pictures of my visits to Scotland with new eyes now, I can recognize the once volcanic areas there. Awesome.
Appreciate your curation of previous work, Shawn. Your more recent subscribers who watch this will benefit greatly and it is a solid review. The joy of geology is evident in your reaction to spotting those superb pillows. I think pillow lava is your favorite to explore -- perhaps -- because it's more interesting to think and talk about.
So much fun. My last formal geology class was in 1975, so I am enjoying your channel immensely. Fell in love with Iceland when the new island was formed in the 80's - Surter, I think it was called. Geology never fails to capture my attention. Your teaching style brings out the enjoyment of the lesson. Thank you.
Surtsey Island was formed in the 1960s on the south coast of iceland, I remember it happening and watching it on the news, it was black and white tv then but was still so very impressive.I remember when humans first went on the island, all dressed in protective clothing so they did introduce anything from the main land, There is a new island forming off Japan at the moment but no news coverage much which is a shame
My last geology class was in 1964, but I remember everything especially the field trips. I found a trail bite. I put it away so safely and so carefully that I have never found it.
Thank you for the guided walk along this coastline. You make me feel as though I am one of the tourists on the bus, but with a fantastic , knowledgeable guide!
Thank you for describing in such detail the varieties of lava flows! I lived in Hawai'i for three years and was able to see the layers from successive lava flows. We were allowed to walk on lava that was two weeks old, and it was hot!!
Brilliant updates today and yesterday Shawn 👍👍. The way you handled all of the information that came in was just first-class. And not forgetting the information from various real-time sources that was supplied by Amanda-Jo. The Coastguard videos on particular were so informative. Great work from all. 🤜👊🤛
Thank you for the info. so interesting! Are the shape/appearance of pillow lavas affected by the temp of the surrounding water? Is the look of pillow basalt different when formed in glacier cold water vs pillow basalt formed in warmer “Hawaii” temp water?
How is the age of rock/lava determined (i.e. 800-1200 years ago)? I remember, as a kid, learning to count the rings of a tree trunk to determine age. Same kind of concept? Thanks for all your videos.
Having watched video of Hawaiian eruptions; I've seen further variations on the pillow basalt/lapilli/subaerial lava sequence. When a lava flow enters a water body (especially the ocean, with wave action) pillow lava forms when the lava enters the water. Some lava also shatters into sand/gravel sized pieces, especially if there is surf to wash away the accumulating lava fragments and create a cliff for the lava to spill from in thin streams. Could you tell a pillow basalt - black sand beach deposit - lava flow sequence from a sequence from a subsea vent? Your example location looks likely to have had such - whether preserved in recognizable form or not.
Very interesting Professor Willsey. I have a question about the rift. It enters Iceland in the South and exits in the North. I have tried to follow it through out the land but can't find it in some areas. Can you explain why, when it exits in the north, it seems to stop and start up again around 100miles to the West. How does it make this move? I understand the Mid Atlantic is about 40,000 miles long, does it stop and start in another area ,any where else?
@@shawnwillsey still seems like something was different. Composition, conditions. I didn’t see anything like eastern Washington in Hawaii. I’ve been pretty deep inside both ocean level caves and lava tube caves up the mountain. I’m.l not trying to be argumentative, but needing a million or so years of erosion doesn’t add up and seems like a bit of an easy answer, and one of such that is pretty much unprovable and unarguable. Thanks for your reply.
I was pondering this video, wondering if there were any fossils therein. I’m guessing not, given the violent nature of creation at the time. Probably a dumb thought, but….

I am an old Icelander and I really appreciate your videos. They are very informative and enjoyable.

Much appreciated Shawn! How I'd love to be there to touch/feel all that you point to!

This is a great review for me. Gotta love rocks!
Very interesting. Thanks for the update close tour.

Very informative, thank you for taking the time to post.
Love your educational videos and the drawings help me so much. Thank you very much.

Very interesting..love your videos!
Thanks for sharing your passion!
I don’t think I’ll ever look at rocks the same way again!
thank you for teaching us
Thank you for your work. Very interesting.
Viele danke. für ihren infos
Vielen Dank, für dieses interessante Video
Ich würde das nie so sehen können, wenn es hier nicht gezeigt würde
Vielen Dank für die Mühe
Alles Gute😊😊

Can't wait to see this next year!
Great content. You’ve made basalt interesting!
Thank you 😊 fascinating ❤
amazing work ! greets from argentina.
Thank you!
Thank you for the info. so interesting! Are the shape/appearance of pillow lavas affected by the temp of the surrounding water? Is the look of pillow basalt different when formed in glacier cold water vs pillow basalt formed in warmer “Hawaii” temp water?
No. Water temp difference is negligible.
How is the age of rock/lava determined (i.e. 800-1200 years ago)? I remember, as a kid, learning to count the rings of a tree trunk to determine age. Same kind of concept? Thanks for all your videos.
Lovin it!
🤘😎🤘
Wow interesting really need to explore Iceland. Is that graben system part of the mid-Atlantic rift?
It's related to the overall tectonic boundary here.
Takk fyrir! Thank you!

Lots of active pillow lava formation YT vids off of the Big Island.
Wow, this “imminent” eruption is apparently taking its time. My biggest fear is
- it will wait until the day I go to Iceland in September.
Are the Pillow lavas precursors to Columnar Basalt?
No. Pillow lavas need water interaction to form. Columns typically do not involve water interaction.
Boom
Short answer: Phreatic eruption! Aka big bada boom!
Date of 115K to 120K years ago puts in the Eemian interglacial period?
Why don’t we see hexagonal shapes from lava flows anymore? Only in ancient lava flows? In fact it seems to be way different
Flow needs to be somewhat thick and then you need erosion to expose columns.

No fossils here.
