The Active Volcano in Papua New Guinea; Long Island

[@GeologyHub]

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?

[@Sunny_Now_and_Then]

I do. If Hunga Tonga could blast so high why not Long Island basting that far??

[@edwardfletcher7790]

Anything from that long ago tends to confuse myth with fact. Accuracy deteriorates with time.

[@erinjackson6243]

I won't say those stories are 100% accurate, but I also can't discount them. We've seen how many times local peoples have told stories that were handed down from their ancestors about a disaster(s) and they ended up being correct. Stranger things that flying boulders have happened during a volcanic eruption lol.

[@RedTideRTS]

I believe it’s possible and even probable. The speculation is fun, though!

[@amateurmakingmistakes]

I mentioned in one of your previous videos that the captain of a plane I was flying showed me a house sized boulder on the mainland as we were flying along the coast, opposite Long Island. This was in 1988 and this boulder was very easy to see, as it sat above the jungle and hadn't been overcome with greenery. That boulder looked unlike any other rock structures near any of the other volcanoes in PNG. So, it if's a legend, I'll buy it. If I remember rightly, that huge boulder is east of Saidor.

[@lilysceeliljeaniemoonlight]

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

[@SeventhSamurai72]

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

[@davidc6510]

Great update! Thanks for sharing.

[@ZE0XE0]

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.

[@genericalfishtycoon3853]

Yeah it would be nice to know where each pic was from.

[@amateurmakingmistakes]

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.)

[@simonlemerveilleuxdelisle3779]

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.

[@gaius_enceladus]

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!

[@miklov]

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 ^^.

[@I.amthatrealJuan]

Most "active" volcanoes aren't going to erupt in your lifetime.

[@miklov]

@@I.amthatrealJuan This is true. But it is the same with being out in the woods during a thunder storm. It is very unlikely to get hit but I'd still worry =)

[@Earthneedsado-over177]

Living near a volcano would take your mind off of climate change and world war three.

[@skybattler2624]

Meanwhile, in the Philippines...

[@StuffandThings_]

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.

[@priceringo1756]

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

[@nortyfiner]

Short answer: no to both. Longer answer: the ocean floor is incompletely mapped and constantly changing, especially in the Western Pacific. Which is why every few years, you'll see news about a submarine running into an uncharted underwater mountain. As for detecting underwater eruptions, pretty much the only ways we know they happen are seismometers and visual observations -- signs like discolored water, floating pumice, plumes if they're close enough to the surface, and so on.

[@erictaylor1322]

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

[@jonathonschott]

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.

[@aldenconsolver3428]

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 :)

[@Earthneedsado-over177]

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.

[@michaeldeierhoi4096]

Research geologists or volcanologists spend ten years in college because the science needed to understand volcanoes is so difficult and so much to learn.

[@StuffandThings_]

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.

[@wacojones8062]

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.

[@johnsheehan5109]

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

[@mickaelsouza9087]

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?

[@Mary-JosephineSalung-fc3sw]

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

[@adriennefloreen]

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.

[@MFBURNS7909]

Ty! 🙏

[@ben4life988]

What was the 1666 bc eruption scaled on the vei?

[@Akechi_The_Phantom_Detective]

6. It would’ve needed to eject at least 100KM of cubic material to be a 7.

[@dbm52]

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

[@AndisweatherCenter]

[@johnmccartan939]

Erupted !!! not irrupt it 🤣

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.

[@mikeyd946]

Wow 😮

[@RobertDPore]

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.”

[@Dragrath1]

Looking at this in context with Nick Zentner's Crazy Eocene series last winter it looks to be largely associated with the rise and fall of the Laramide mountains a.k.a. the Idaho volcanic arc. Most of the volcanic activity was focused to the west but like the Andes significant uplift and mountains existed beyond that (with other volcanic centers related to this story in the Dakotas and the shift from compression to extension was probably pretty important. Given this geologic story is still only starting to come together. The geology of Idaho Montana Wyoming the Dakotas down into the southwest with New Mexico Colorado is very complicated and there seems to surprisingly be relatively poor dating and sampling for much of the geological features. I wouldn't be surprised if no one actually knows the full story rather has based their understanding on extrapolating a few samples from field studies.

[@kingawesome0858]

Nice:)

[@aldito7586]

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

[@howitzersupercell240]

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

[@michaeldeierhoi4096]

There are hundreds more volcanoes throughout the world with far more dangerous eruptions and yet people will continue to live near volcanoes in their area. The number people killed in a given year by volcanoes is actually fairly low compared to other natural threats such as flooding. Also thee catastrophic eruptions like this one has had are not frequent enough to stop habitation.

[@jakobfromthefence]

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

[@jasonhaymanonthedrawingboard]

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.
