It is debatable whether large boulders were truly ejected to a whopping 70 kilometers distant. It is equally as likely that the stories of secondary craters from these falling boulders were exaggerated and that they were instead very low-density pumice. Do you think the stories are correct?

Concise, short videos filled with facts on a subject I really enjoy. I dig your style, dude! Thank you 😁

I love your videos. very good information and presented well in an easy way to understand. I think my only comment is that it might be a good idea to label the locations where photos you use are from. You use a lot of photos of examples of what things could have looked like, but some people might mistake that as thinking its a photo of the actual volcano the video is about, and some people may want to look for more photos of the volcano in the stock image.

Soon as I saw this video I instantly had to view the island and volcanic caldera in real time! Epic. Absolutely Phenomenal!

Great video! I'd love to hear your take on the Karkar Island volcano. It killed a couple of Aussie volcanologists in the late 70's. A decade later, I flew a half dozen other Aussie volcanologists inside the crater of the volcano, which was erupting steam. Interestingly, there was once an airstrip at the SW end of the island called Daup, which our airstrip notes mentioned a 300' high cone that had eroded on one side and which produced severe turbulence on the approach into Daup. That airstrip is now barely visible, swallowed by jungle, but that 300' high cone has also disappeared, probably due to continuing erosion. I'm not sure of the technical term of that cone - secondary or side vent or cone - but it was at the base of the 6,000' volcano. (Our now-defunct airline used to fly there 7 times a week during weekdays.)

And less than a hundred years before, not that far from Long Island, another volcano known as Billy Mitchell also produced a VEI 6 caldera forming eruption. Needless to say, that region is known to be extremely active geologically speaking.

Great update! Thanks for sharing.

I don't think I'd be very comfortable living next to a volcano. Especially not if it is on an island that might be tricky to evacuate. Though I'd like to visit active places too, but I'd probably be worried the whole time ^^.

Since you're doing the PNG volcanoes, I'd like to see a video on Mt Lamington! Also - Tavurvur and Vulcan! I was sure that there was a rugby league game in Rabaul that was cancelled quite a few years ago because of the eruption of Tavurvur and Vulcan. I can find no mention of it though. Maybe a PNG person could find a news article on it? I was unable to find anything! If that happened (and I think it did) it would surely be the only league game cancelled due to a volcanic eruption!

I'd love to see a video on the 1465 mystery eruption. Apparently might've been a vei 7.

Could you perhaps cover Garove volcano? It is yet another caldera volcano in PNG, except its location is rather odd, right in the middle of the Bismarck sea. The lava cone volcanoes of Bougainville would also make for a pretty neat topic, as they are a super rare and very weird volcano type likely caused by the Ontong Java plateau subducting iirc.

Do we have an accurate count of current undersea volcanos? Besides seismometers, can we detect newly erupting volcanos?

I knew there were different kinds of volcanoes but I had no idea there were so many complexities. Fascinating how many different kinds of rock come out of volcanoes. Love these videos, I watch every one.

As I know you are an arizona resident, you should do the geological history of picacho peak, if it's interesting enough to warrant some coverage that is. I drive by it quite frequently and since subscribing to your channel and watching some of your other arizona videos that mountain has made me wonder.

Much nastiness around the area in WW II battle of the Bismark sea and the Fight NW up the coast. My dad was at Buna for a period of time as a Medic. Buna seems to not have been rebuilt after the Tsunami wiped it out. Keep up your very good reports.

If anyone lives in one of the small towns there or visits there please collect seeds for all the plant and some volcanic rock and soil that they grow in, it's probably like the Galapagos islands for plants, most volcanic islands are. And the next time it has a major eruption they could all go extinct, send them to people elsewhere.

I wonder if like with Hunga Tonga the explosive power of the eruption was oversized compared to its VEI. Like, I could definitely see some potential for water interaction there, either from a previous lake from those other calderas or seawater making its way to the magma chamber. Either way, I think such an option would open up the possibility for those rocks to be flung 70 km. A scaled up Hunga Tonga would be quite impressive I'd imagine, and probably pretty similar to Krakatau.

GH great presentation. A minor quibble I believe the scientific notations for dating are CE and BCE, and not the antiquated AD and BC

I already live on Long Island. - I don't need to live on one that is going to blow up !

PNG volcanoes.......... I also would be interested in your geological description of Karkar.

Awesome video! If it hasn’t irrupt it in such a long time imagine what would happen if it erupts in the future?

Howdy, is that red sand grain sized mineral at 0;29 Jasper? And any suggestion about how it got there? Keep up the good work :)

Las Vegas isn't the best example: people tend to just think of the strip and not the USAF base or airport or ...ugh... North Vegas.

Would it be possible for you to do a Geological Oddities video on Hell’s Half Acre (actually 320 acres) in Wyoming? I just visited this place and found the interpretive sign uninformative and the Wikipedia pages lacking in citations. It would be nice to know why the rolling hills of Wyoming ranchland suddenly turn into "Bryce Canyon but covered in alkali.”

What about the lake?, I am curious as to where the lake water is coming from and how.

What was the 1666 bc eruption scaled on the vei?

Wow 😮

Ty! 🙏

Nice video, these caldera forming eruptions are so fascinating, please bring more videos about volcanoes like that. Dnd I would like to ask a question about the mechanisms of magma chambers: Is it possible for a volcano to have two interconnected magma chambers, each with a different type of magma? Por example, would we have Magma Chamber A with andesite and Magma Chamber B with Basalt? And at the same time would both produce eruptions of different types? Chamber A producing a summit plinian/sub-plinian eruption, and Chamber B producing a fissure or cinder cone hawaiian/strombolian eruption. It's possible?

Nice:)

The Long Island Volcano...is that near Southhampton?...😁 NY

With the three large eruptions from it's history, the whole island is just too dangerous to live at.

When will Long island volcano 🌋 erupted again..

Wana do long doit wanna short so do it but need amkralss eruptions

The Bismarck sea seams to look like a giant caldera. it could be one of the largest magma chambers on the planet? considering this I suspect it highly like due to it location on a plate boundary. The fact that most of the volcanoes are highly explosive in the area who give you some idea. Though not a traditional super volcano. it quite possible that a multiple vent eruption could take place. Draining the the magma chamber forming a caldera. Especially it there lots of lateral magma intrusion. It know that there is a high concentration of calderas in Indonesia. much of the south western Pacific as a whole. It may just be me. but the island form a long chain of islands in an archipelago. that form a loop back toward papa new Guinean. New Britain and new Ireland forming a the outer edge of a truely massive caldera. If I’m not mistaken it is a triple juncture between plate boundary. Ring of fire should be ring of death. Great you mentioned Long Island. But it must be seen as part of a truly massive outer caldera. Dot to dot.

Well. I’m not moving to Long Island anytime soon.

Long 🌋

Never mind just do eruptions

earth is clearly a teenager.. pimples and stuff

Eyafjallajökull put out a Volcanic Ash advisory Eyafjallajökull Volcano Volcanic Ash Advisory: CONSIDERED IMMINENT OBS VA DTG: 10/0813Z I can't find much info on this

Great work - beautifully researche3d and presented.
