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?

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.

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.

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.

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.

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!

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?
@nortyfiner2 жыл бұрын
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.

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.
@StuffandThings_2 жыл бұрын
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.

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.

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?

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.
