Japan Officials: Ground subsidence spreading after quake — Concern about sinking buildings being damaged — Only an inch can jeopardize stability (VIDEO)

Title: Quake-caused subsidence spreads
Source: NHK WORLD English-
Date: Dec. 17, 2012

The Environment Ministry says nearly 6,000 square kilometers of land across Japan have subsided by more than 2 centimeters in the last fiscal year. […]

This level is judged to have a potential impact on buildings’ stability.

The ministry says Kesennuma in Miyagi Prefecture sank deepest by 73.8 centimeters, followed by Ichikawa in Chiba by 30.9 centimeters [Fukushima Prefecture NOT tested]

The ministry officials say the subsidence is attributable to last year’s March 11th earthquake. They have expressed concerns over the spread of subsidence and further damage to buildings.

    Cross this with the previous posts about ongoing structural integrity and it begins to paint a picture that just keeps getting worse.

    Just recently posted a list of the 13 prefectures in Japan that have nuclear power plants, so we could keep an eye out for earthquakes, etc. in these areas:

    13 Prefectures with Nuclear Power Plants:

    1. Miyagi
    2. Ibaraki
    3. Niigata
    4. Hokkaido
    5. Fukui
    6. Aomori
    7. Ishikawa
    8. Shimane
    9. Fukushima
    10. Kagoshima
    11. Saga
    12. Ehime
    13. Shizouka

    Two of the prefectures from the list are mentioned in the article above.

    Miyagi prefecture had the worst subsidence, and Ibaraki had the third worst.

    73 centimeters in Kesennuma is a lot. What we need is the rate it is sinking. An amazing video of the town being destroyed by the tsunami here


    Fishing and tourism were the major economics. How will they live?
    What are the chances that fukushima will be even more ruined, with no human access possible? The ensuing global devastation will make it difficult or impossible to handle other nuclear plants around the world in years to come. The term E.L.E. seems ever more likely. Man was one bad monkey

    Always wondered how much damage liquifaction did in Japan.

    Any damage to any of the npp's there?

    Guess we'll never know.


  • Johnny Blade Johnny Blade

    Yeah,"give TEPCO an inch and they'll take & contaminate a mile(s)"!!

    A big difference between liquefaction and part of an island you are living on is being taken back down below the earth's crust never to be seen again. One of the measurements of ground lowering about 2 feet 6 inches (73cm of subsistence) means that part of the island dropped and is not coming backup.

    Liquefaction is a temporary saturation of earth (usually sand with water) turning the mix into a liquid reaction like quicksand but turning back to a solid when the liquid leeches back out.

    The time spent shaking during this Great Quake happened as one of earth's tectonic plates was moving and riding underneath a different and opposing tectonic plate snagging some of the Japanese island and taking it down with it.

    Eventually all of Japan will be subducted, never to be seen again. In the meantime, maps of parts of the Japanese coastline had to be redrawn because some of it disappeared forever during this Great Quake.

  • crystalwind crystalwind

    I guess we know where the NPPs are going to go.

  • razzz razzz

    Let's just say the subduction of Japan is constantly going on.

    Fukushima dropped also during the Great Quake then the tsunami hit. Notice the report in the article neglects measuring Fukushima but using mean sea level (during spring tides?) as the zero elevation benchmark number, 'O.P.' in Japanese speak, I'm sure they can tell the difference between current surveyed ground elevations and pre-quake elevations.

    Fukushima Daiichi's nuke site is not sitting on bedrock but some type of raised hardened sea floor sediment. Don't think I've seen a pic of a rock outcrop anywhere in the area yet.

    Here at page 23… http://icanps.go.jp/eng/120224Honbun02Eng.pdf … the flooded site elev. is called out at 10 meters. Was that after or before the quake struck? Conceivably the site dropped 3 meters including the seawall protection before the tsunami arrived making it a 7m elev. An extreme scenario?

    They say groundwater mixes with their cooling water but is it fresh water or part saline?

    Poor soil conditions and more water than they know what to do with (other than dump it into the Pacific) just adds to the complications. I have no idea how bad things are there except they don't know where the melted cores are. I suppose you can temporarily repair the buildings. You can't temporarily repair melted cores even if you knew exactly where they are.

    I just hope the whole place doesn't become irradiated to the point no human can work there.

    Reading these old news reports is really something. Here Unit 1 already blew but Unit 3 hadn't.


  • dka

    I think that pool 4 will fail. Does not change my every day life because I don't know when. I am just more attentive to others.
    Seriously, I think that we would be lucky if does not fail.

    I read where Michio Kaku is calling on the authorities to nuke the entire site and force it into the ocean. Once underwater, the ongoing poisoning of the atmosphere would stop and the hot materials could be collected by a submarine. It would contaminate the Pacific horribly, but spare the atmosphere and perhaps technologies will be created to mitigate the damage to the Pacific Ocean. It seems totally crazy, but the only solution I have yet to hear that sounds like it might work. Dealing with the problem undersea just seems like the least damaging way to deal with it. Maybe I am wrong, I am no expert, but I've read produce in California is already reading three times backgroud, inside the fruit. This trend can ONLY continue to worsen through bioaccumulation until the atmospheric poisoning is stopped. Anyone have a better idea?

    • richard richard

      yes Usefulbreather, I've a better idea. Don't create more pollution and misery for the Pacific or the rest of the world.

      Nuking fuku-d is a gutless idea, designed to stall the issue of pulling the place apart bit by bit, hand over hand.

      Any path that doesn't result in the immediate deconstruction of the site is usually a way of hiding or stalling the truth from the main stream public. Burying or cementing or nuking just deny the truth of the horror the world faces.

      The Japanese need to send themselves in and hand over hand pull the place apart. Yes, people will die. A horrible death at that. But that's not my fault, that's not the fault of the flora and fauna of Earth. It's the fault of the governments and corporations of certain nations. Send those people in first, let them die cleaning up the toxic poison that have released onto the world.

      Michio Kaku idea is utterly brainless, gutless and probably the result of japanese brainwashing. It is not to be considered.

      Send in the daily busloads of people NOW!. We are already close to two years and nothing is being done. Fuku-d needs to be attacked with every level of human capability, now. Not tomorrow, not next century.

      People will die, better get used to it.. the issue has been stalled for this long to reduce publicity and to continue the deadly farce called the nuclear power industry.

      When 1000 people die each day trying to 'decommission' fuku-d, then maybe the general public will wake up to the…

      Then, Usefulbreather, unfortunately either you read someone's intentional disinformation or their lazy haphazard research would be my guess. Maybe you can provide the link to his statement and enewsers can explore it and try and figure that out. The reason why it is important to do that is because the claims are the complete opposite of his statements that Admin has posted from him since the beginning of this disaster. Getting that cleared up would be good.
