Mt. Fuji Volcano In 'Critical State' After Quakes

An anonymous reader writes: Mount Fuji, in addition to being a picturesque landmark and an important part of Japanese culture, is also an active volcano. Its last eruption was just over 400 years ago, but its location — where the Eurasian, Pacific, and Philippine tectonic plates meet — mean it will always have potential for eruption. A new study (PDF) has examined the pressures around Mount Fuji in the wake of several recent earthquakes, including the magnitude 9 tremor that unleashed the destructive tsunami in 2011. The researchers now say the volcano is in a "critical state." According to the study's lead author, "The volcanic regions are the ones where the fluids trapped in the rock – boiling water, gas, liquid magma, which cause an eruption when they rise to the surface – exert the greatest pressure. The seismic waves add to this pressure, causing even more disturbance." They have no way of predicting when an eruption might happen, but the potential seems greater than ever.

An example of an English word with 16 letters would be "conservationists". It's quite easy to read because my brain breaks it up into letter groups that occur often in English. Groups like con, and tion, and ist occur all over the place and therefore make the word easy to recognize. EyjafjallajÃkull on the other hand doesn't have any common letter groups I would normall see in english. I don't even know how to properly pronounce Eyja or fja. The only part that's really familiar to English speakers is alla, and perhaps kull.

      In Icelandic 'o' and 'ö' are fairly subtle variations on the same sound, the difference betwee 'o' and 'ö' is only a matter of moving your tongue about 4-5mm forward. Icelandic is near near-isomorphic with with Ancient Norse to the point where some Icelanders can actually stumble their way through inscriptions transcribed into modern alphabet from rune stones over a thousand years old and many can read 12-13th century manuscripts similarly transcribed to modern alphabet pretty clearly, in fact teenagers in Iceland are sometimes required to read portions of sagas in the original medieval Icelandic in secondary school. You can consider Icelandic as something akin to a modern dialect of Ancient Norse whereas the modern Scandinavian languages on the other hand have evolved very far from the original Ancient Norse. The difference is about the same as between modern English and the language spoken in the UK in the 10-13 century. Come to think of it an Icelander would probably have much better luck reading early medieval English than a modern English person. Try getting a Norwegian, Swede or Dane to read a 13th century Icelandic saga manuscript and you'd not have much luck either.

Once the pressure drops enough, the gas ceases to be soluble in the magma and it's the expansion of the gas that causes the violent eruption. It follows that relieving the pressure could easily trigger the eruption you are trying to prevent in this case.

    With an abundance of sustainable and reliable energy, survivability of an event such as a volcanic winter would be drastically increased. Energy is the only limiting factor in producing a 100% self-sufficient and self-contained living environment, not only in space, but on earth as well. Energy availability would be instrumental in facing such a disaster, and with adequate preparation we could manage quite comfortably.

    However, if the green dream of a world powered exclusively by renewables were realized, humanity would have no hope whatsoever. The lights would go out indefinitely, and any sort of civilization would promptly collapse, with only a handful surviving in miserable conditions. Renewables are not reliable, and are incapable of sustaining civilization through such a crisis.

    While efficiency is a laudable goal (to which most engineers already aspire), eking by with extreme conservation is highly anti-productive, and exacerbates environmental and societal problems. Energy is not a disease to be eradicated, but a resource essential for enabling greater levels of recycling and reuse, and ultimately a sustainable high quality of life with minimal environmental footprint. With prosperity, population also tends to level off, solving that problem as well.

    Energy is only a problem when it is derived in an environmentally destructive manner, as with mining and extraction of fossil resources, or the vast and inefficient collection, storage, and distribution infrastructure for wind and solar. These sources also require extensive mining for the raw materials comprising the infrastructure, and the fuels required for transportation in both cases.

    Owing to a far superior energy density, nuclear energy necessitates very little mining and supporting infrastructure. Molten salt reactors like LFTR use nuclear fuel roughly 200 times more efficiently than todays LWRs, and with passive safety and no need for water cooling, they can be sited virtually anywhere. For perspective, a 1GWe LFTR plant would be roughly the size of a Walmart. Incidentally, there are upward of 10,000 Walmarts, which would accommodate 10TW of LFTR power production--enough to provide for 10 billion people at US per capita power consumption.

    Each year, a 1GWe reactor would only consume about a ton of thorium, and produce about a ton of fission products. All of the fuel required to power the world for a year could be mined at a site not much larger than a Walmart itself. However, it could instead be recovered from the tailings of rare earth or other mining already in progress. (For reference, a metric ton of thorium fits in a sphere 55cm (or 1.8ft) in diameter.) A plant could easily have decades worth of thorium on hand.

    Of course, the picture wouldn't be complete without considering the waste. A single GWe of generating capacity is enough to power a sizable city, producing 1t (metric ton) of fission products per year. One might worry that these are going to accumulate and produce an intractable problem, but in reality the radioactivity is constantly disappearing, and will reach a steady state when the creation balances the decay. As 83% of the fission products of a LFTR are stable after a decade, and the rest no more radioactive than ore in 300 years, the sum total of waste produced for one GWe of power, will gradually build up to, yet never exceed 59t after 300 years. This is a trivial amount, which is still overstated as many of the fission products have uses. (radioisotope thermal generators, sources for medicine or food irradiation, etc.) Even if politics prevents doing something useful with it, it could still be safely stored in a small room on site.

    A storage facility near it contains another 6000 spent mox fuel rods. The smoke of the fire is plutonium oxide and chloride which is fatal to humans at doses of 1-10 micrograms.

    There is little doubt that if that happens at Fukushima the fallout would be carried by the jetstream over the US and, eventually the entire Northern hemisphere.

    How many tons is that 6000 spent rods?

    Roughly 850 tons on site.

    Then remember exactly how big the Pacific Ocean is and how large, comparatively, a microgram is. A microgram is only 10^-12 of a ton, area crossed is a square fall off rate.

    8.5^14 fatal doses. More than enough to go around and around.

    Could it immediately pollute the ocean and cause problems? Sure! Would the fall-out in the ocean cause a long term problem?

    Absolutely. I described the effects which would last as long as the decay period, which is 25,000 years as it is cycled through the food chain over that time through bio-accumulation - assuming it lasts that long.

    you are worried about the toxins that humans failed to plan for when a volcano that's been dormant for a long history suddenly might be a little closer to eruption?

    I would characterize it as concerned enough to agitate for action. Though another poster pointed out that the fuel rods are being removed at a pace that indicates that this threat is actually understood. The revised figure is 400 in the spent fuel pool, still quite a large threat however, great news there and hopefully a threat that is resolved soon!

    Be worried about the loss of life from the volcano going off, and the loss of life from the climate change that a large eruption would cause (famine, loss of utilities, etc).

    On a purely vicarious level an eruption of Mt Fuji wouldn't affect me, a pu fire would.

    Or, if you must be scared of nuclear stuff, be scared of the fall out from all the nuke warheads and fuel stored close enough to Yellowstone that would be vaporized in the expected eruption.

    I am not aware that Yucca mountain is operational and the DOE characterized it as unsuitable, let me know if you have a link indicating otherwise. If it were operational and fully stocked it would present an ongoing threat that would dwarf this one (which is one of my chief objections to the facility) however both scenarios pose a threat so serious that it would be like comparing being crushed by a 850 ton rock to a 70,000 ton rock, you are equally dead.

    On reflection its a possible solution to the Fermi Paradox.

If you want to set a time limit on it - say, 100 years - then you can talk about probabilities and an 2if", but without a time limit, you're talking about "when". There no reason to believe that the area has gone quiet, and plenty of evidence of continuing magma movement in the sub-surface.

    In fact, Yellowstone may be the biggest volcano threat in the world.

    Personally, I'd go for Vesuvius being the biggest threat around (2 million or so people in the blast zones). But I'm not particularly familiar with Popacatapetl and Mexico City, so I'd have to put that one on the table too.

    Yellowstone might be able to destroy North America (in the sense of "unfit for human habitation" for centuries), resulting in around a half billion deaths. [SHRUG] There's another 6+billion to go. Our species has been down in the low thousands before and come back (probably the result of climate change ; possibly due to volcanic forcing).

    It might last for a while, but conservation is still not sustainable.

    An oddly strict definition of conservation....not using it at all would fit under the definition of conservation. Or saving it all for a global emergency to survive a volcanic winter when solar and hydro give out. That's what I was getting at. There's no reason we shouldn't know where it is and be ready to mine it just in case.

    I said nothing against going to nuclear as a primary fuel source. It's perfectly feasible except for one small problem - no one will do it or approve it. With that standing as a major roadblock to this day, we still need to conserve what we're using.

    It's worth noting that the magnitude 9 earthquake didn't come close to threatening the stability of the cooling ponds.

    The damage to the foundations mean the entire building leaning over. TEPCO's status page for the reactor reveals they are building a support structure to stop the spent fuel pool from falling.

    So you're looking for a much bigger earthquake in a region that already released most of its geologically built up energy in a magnitude 9 earthquake.

    I see your supporting your adgenda as a Nuclear apologist again.

    Because obviously, Japan will forgot how to pump water. A few diesel generators and some hose means that your scenario doesn't happen - even if you somehow came up with the huge earthquake and the structural failure.

    A plutonium fire splits the hydrogen and oxygen and the water ceases to exist, so that simply won't work

    It's so peculiar a failure mode that I have to quote the whole thing:

    All this "NIMBY" greenpeace anti nuke fags really just don't know what they are taking about, anyone who knows about nuclear reactors will tell you that they are really great, super reliable and that the only reason that we have to pay for electricity is because it's waaay too cheap to meter it from a nuclear reactor and the utilities had to pay for meters.

    I've often thought, "I would like some strontium 90 on my breakfast cereal" because it is tasty and good for you, plus you will win every fart contest. Recently it was conclusively *proven* that not only can you get a great suntan from the core of a reactor, but that radioisotopes have Vitamin C in it, so my advice to people would be if you are feeling a bit of a sniffle coming on, get yourself to a local nuclear reactor and ask to cuddle up to a couple of fuel rods and get toasty.

    Chernobyl and Fukushima proved how safe Nuclear power is and we should all want one near us. Whilst evacuations of these areas have occurred Bruce Willis proved that you won't die at all from fallout from a nuclear reactor in "A good day to die hard". He lived and was stronger so we should move people back there so they grow up to be just like Bruce Willis.

    Nuclear is perfectly safe and we can all have a nuclear future, in our back yards, today!
