The Active Volcano in Japan; Mount Fuji

[@sometimestraveller]

As someone living in Kanagawa, able to see Mt. Fuji from my back window, this one was specially interesting to me!

Wow!

Thanks for all of your hard work man!

[@owainw3501]

I love the videos. It's better than most channels

[@donaldduck830]

It is most excellent that you don't scream how dangerous Mt. Fuji is but give a very balanced and reasonable estimation that it is dangerous, but not as the tabloids claim and my guess is that it is probably among the closest watched volcanoes on Earth.

[@Vesuviusisking]

What’s the other closest watched volcanoes

[@donaldduck830]

@@Vesuviusisking I would guess popocatepetl, Etna and Vesuvius. Mouna Loa and Kea. Volcanoes you can reach easily, that are quite active and that endanger many people. I mean who cares if a volcano under the antarctic ice shield erupts? Some (2 or 3) currently do and almost all current melting in antarctica is due to that, but most people disregard them^^

Thank you for the details on Mount Fuji (or Fuji-San) and it's evolution over time and the potential risks it poses. I shall be interested to read up on the historic accounts of the Hoei 1707 eruption and the accounts given by people of that. It certainly is a beautiful sight to behold even from afar.

[@carolynallisee2463]

It's interesting to note that when a new volcano begins erupting, the first materials it produces almost always has a basaltic or basaltic andesite chemical make up. In the late Dr Peter Francis' book, 'Volcanos: A Planetary Perspective', he mentions the hypothesis that all volcanic eruptions are essentially basaltic in nature, but that this basalt is modified by various processes to form the other types of magma. Has this hypothesis become generally accepted in the volcanological community? Because of their shape, and because they almost always erupt explosively, basalt isn't the type of volcanic rock I associate with Japan's volcanoes. So hearing that Fuji-san once produced basalt is very surprising indeed. Mt. Fuji is one of the world's most symmetrical and beautiful volcanos. I note that Mayon is mentioned in another comment, and I saw a picture once of another volcano in South America that was an almost perfect conical shape, with sides perfectly straight rather than concave. I can't recall the name of this volcano, and that photo is decades old now, so it may no longer look like that. But there is something very pleasing to the eye with the smooth, regular slopes of an almost perfectly formed volcano.

[@davidcranstone9044]

Would the 'South America' volcano be Arenal in Costa Rica? If so it is actually in Central America, but it does match your description.

[@zyrians]

Ineirie Vulcano in Indonesia also almost symmetrical, only the peak is slightly curved.

[@carolynallisee2463]

@@davidcranstone9044 I thought the volcano I was thinking of was called Izalco, but I'm not certain. I'm sure there must be more almost perfectly symmetrical volcanos out there, and I've never heard of them, or seen images of them. So Arenal can be added to the list!

[@carolynallisee2463]

@@zyrians another one for the list! As I said in amother comment, there must be a fair number of almost perfectly shaped volcanoes that I've either not heard of, or have, but not seen a picture of. I guess the stable slope angle must be responsible, and that things like erosion, eruption pattern and eruptions from flank and parasitis vents are what determines any imperfections. That said, the three explosion craters on Mt Fuji clearly doesn't detract from its symmentry when viewed from certain postions round it.

[@perrylim9728]

I admit, that more information about Mount Fuji’s hazards are actually in the Japanese language. Especially the 864 AD Jogan eruption which now updated the lava flow hazard map, covering over 2 dozen municipalities in 3 prefectures including extreme western Kanagawa. And regarding volcanic ash, the cabinet office even created a worst case scenario of ash fall if the wind direction is from the west southwest, aimed directly at Tokyo.

[@joshjones3408]

I really hope people that live around stuff like this watch your channel....if people can get tru Info like this saves lifes it's simple...just watch , that's all they got to do ....👍👍👍👍👍

[@andrewjones-productions]

As someone living in Futtsu, Chiba and seeing Mt. Fuji across the entrance of Tokyo Bay, over Yokosuka, I have a perfect view of Mt. Fuji from a huge picture window in my living, this is very interesting. The 10cm ash line practically smashed right through my house. Charming... We'd be safe from any lava flow where I am, but that amount of ash would cause mayhem without a doubt. Makes me think that I should have the silly wood-deck style boards on my balcony removed as that amount of ash accumulating will not only be heavy dry, but if it were to rain would be an enormous amount of weight. A major eruption of Mt. Fuji would undoubtedly be a major disaster here with important transportation links on Japan's busiest and most important trade route be severely hampered and most likely cut. Of course, the most important thing would be the human casualties that would likely occur. The town of Gotenba and many others would suffer untold damage if not annihilation. Nevertheless, the natural disaster that I think we fear the most is a major earthquake in and around the Tokyo area as well as the 'Nankai Trough' earthquake. Both of which the Japanese media enjoy informing us are imminent. Yet, I've lived in Japan for 32 years and these earthquakes have been 'imminent' for the entire period and the media love to talk about 'during the next 30 years', as the standard timeframe. Probably, not without scientific basis of course. One thing we can be sure of in Japan and that there will be some sort of natural disaster soon, somewhere, so at this time of year as we approach the new year, I think that it is in the back of everyone's minds that the coming year be 'disaster free'. That never happens, but ever since 2011, we haven't had anything on that scale and I hope 2024 will continue to see that.

[@TheOtherKine]

Why worry? You could always just leave, you're not Japanese LMAO

[@commentarytalk1446]

Thanks for the context of how Volcanoes and Earthquakes (and mudslides/typhoons/tsunamis) all interact with the collective society of Japan. Last I was there during the Fukushima earthquake/tsunami and it was a difficult time for the Japanese: As you say there will be many warnings but only one big catastrophe for all those warnings and it will be many times not now until it is now... It does shape the Japanese perspective quite heavily. Thank you again and I wish you all a Good New Year.

[@pinlight97]

Remarkably, had that 2011 catastrophic earthquake happened literally anywhere else just on its it would have been catastrophic. Japan’s infrastructure is remarkable! It took the subsequent tsunami combined with the lowering of the land from that earthquake causing that wave to break over sea walls (also impacting Fukushima) that ultimately did Japan in back then.

[@TheOtherKine]

@@pinlight97 Errrr....... NOPE!!!!! Go watch the news footage of how the water came UP the rivers and swelled out, the coast line was sure swallowed up, but the disaster was made worse due to the sheer size and how the waves carried on up the rivers. Sea walls? Well, they're building higher ones now, but at the time you might as well say that there was NONE. I don't think you understand the way Tsunami works

[@Dragrath1]

An interesting and dangerous photogenic volcano, that said one factor that particularly stands out to me is its relatively high prominence with snow on its summit what are the risks for landslides or lahars?

[@frzferdinand72]

1707 was a wild year in Japan. Full rupture of the Nankai megathrust and the last eruption of Fuji. It was the largest earthquake in Japanese history until Tohoku 2011. Hoei is pronounced "Hoe-aye". Mt. Fuji in general is interesting beyond its beauty as it sits right on top of a triple junction where the Philippine Sea, Okhotsk, and Eurasian plates meet.

[@coyotemontana4558]

I've heard of this famous volcano since I was in middle school to high. Years ago there was a village at Mount Fuji that got destroyed from the lava. But I didn't noticed that there was the Hoei crater that came when Mount Fuji erupted in 1707-1708. Even though that the Hoei crater is there but Mount Fuji will always be a perfect volcano. In the Summer people around the world including Japan climbed up on Mount Fuji to get a perfect view to every part in Japan. And the snowcap has been up on Mount Fuji for years since it's really cold up to the top. I also found out that on Wikipedia it has a list of the other years that Mount Fuji erupted. But get this, when Fuji erupts, the snow melts from the lava and after Fuji is done erupting and goes back to sleep, the snow comes back. Overall Mount Fuji has been the most famous volcano in Japan's history and it has been dormant for 300 years but Mount Fuji will always be famous.

[@CaradhrasAiguo49]

Three centuries is far too short of a non-eruptive period for the tabloids VEI-7 to be possible. According to Smithsonian GBP, Tambora went around a millennium (740 CE +/- 150 years to 1812) without eruptions before its infamous 1815 VEI-7. Samalas (filed under Rinjani) went nearly double that: 600 BCE to 1257 CE

[@Vesuviusisking]

Mount Fuji is a vei 5 volcano

[@timl8258]

I have scoria from the top of Fuji in my study. I collected it when I climbed it.

[@danielsasboot4466]

Took a nap on top of Mount Fuji at the rim. It's not a good idea if you're not wearing sun screen.

[@elric_310]

I've seen studies saying that the M9.1 quake in 2011 affected Mt. Fuji's magma chamber in a way. Maybe the next Nankai/Tokai major quake will bring it to an eruption like in 1707

[@Akechi_The_Phantom_Detective]

Not necessarily, while a volcanic eruption would be more likely after an Earthquake there really isn't much to suggest there'd be a highly destructive or even a very long eruption. Fuji primarily erupts basaltic lava I'd imagine the majority of it's own eruptions would be similar to that of Mount Etna, probably be very beautiful at night if anything. Though it doesn't make the threat of Lahars any less dangerous.

[@星屑-g4s]

Four days after the massive earthquake of March 11, 2011, an Mj⒍4 earthquake, believed to be a triggered earthquake, occurred just above a magma reservoir directly under Mt. Fuji, and Japanese researchers were very concerned about an eruption of Mt.

[@digitaldreamer5481]

I was still in the US Marines in the late 1970’s when we humped to the top of Mount Fuji twice when the Marines still had a north base up there and Camp Fuji that was destroyed by a large leaking fuel bins during typhoon that killed 13 of my fellow Marines. Climbing to the top of Mt.Fuji was breathtaking in more ways than one but the views was something that I will never experience ever again. One of my best friends lives at the base of Mt. Fuji, Yoichi JA1PPH, a fellow Ham operator and owns a nice farm there. One day soon, I will go visit him and his family there. His daughter lives very close to me while she is attending UH-Manoa. Mt.Fuji is the most beautiful volcano ever and well worth a trip to Japan for that reason alone. 🤙🏻

[@plathanosthegrape5569]

Could Sirung caldera be a candidate for the misterious 1808 eruption?

[@jethsemane]

Mount Fuji is Japan's version of Matterhorn because it is situated at the junction of three tectonic plates - Philippine Sea Plate, Amur Plate and Okhotsk Plate.

[@michaeldeierhoi4096]

The Pacific plate also plays a major role as it sits right up against the Philippine and Okhotsk plates.

[@nightowl0815]

So probably Fuji will erupt not with its central cone but secondary cinder cones/fresh ones will do so?

[@ramondulvur]

Could you explain more in depth how can basaltic composition magma produce a plinian eruption?

[@Akechi_The_Phantom_Detective]

Mt Fuji has to be one of the most scenic volcanoes in the world, right up there with Crater Lake. I've always been curious about it's Geological history, not that I considered it to be a threat to Tokyo but it's such a well known landmark. Unfortunately though it's a had a bit of a rough few years because Tourists inevitably end up visiting it and littering all over the place. I believe the Japanese government aren't too happy about that and looking to impose hefty fines as a result.

[@mistysowards7365]

I wonder if tabloids that claim the possibility of Tokyo being destroyed are assuming the nearly impossible VEI 6 or 7 of Fuji. If there was a total catastrophic flank collapse and ultra plinian eruption then I think Tokyo might suffer a very high mortality rate and destruction. But that is probably nearly impossible because of the history of the Volcano and that complex doesn't show any evidence of VeI 7 eruptions ...? Great video thanks.

[@TheOtherKine]

Never say never! LMAO

[@Vesuviusisking]

Mount Fuji is the perfect volcano

[@Benson_aka_devils_advocate_88]

Debatable. There are a couple others that have near perfect symmetry. But Fuji is easier to view as it sits so close to a major city, so it is far more prominent in videos and documentaries compared to others.

Is the basalt type partially responsible for the decrease in height or is that straight plate tectonic related?

Krakatoa and Taal are both much more active than Vesuvius which has been quiet since 1944. Just a few years ago, an eruption and landslide from Krakatoa caused a tsunami that killed hundreds of people living around the nearby coastlines.
