AFP: M5.7 quake jolts eastern Japan Tuesday morning — Almost 200 miles deep — Expert: The big danger is water suddenly draining from Fukushima Unit 4 pool after quake or dropped cask (PHOTO)

AFP, Nov. 19, 2013 at 6:55a JST: M5.7 earthquake jolts eastern Japan […] on Tuesday morning, seismologists reported. No tsunami alert was issued. The quake struck at around 4:10 a.m. off the eastern Honshu coastline […] The tremor struck far down at a depth of 332 kilometers, the USGS added. […]

Japan Meteorological Agency
, Nov. 19, 2013:

AP, Nov. 18, 2013: The rods have remained in a pool of cooling water 30 meters (100 feet) above the ground […] making them vulnerable to another major earthquake. […] A crane may drop a cask on the ground.

Radio Free Europe, Nov. 18, 2013: [Mycle Schneider, an independent nuclear consultant said,] “The big danger is that through a further earthquake or any kind of impact, the water in the pool gets drained beyond a level that can’t be topped up. That would lead to the spent fuel overheating and potentially burning.” […] [Professor Komei Hosokawa, of Kyoto Seika University] and Schneider said the worst thing that could  happen during the operation would be a cask being dropped onto the wall  of the pool, which would result in a loss of water.

The Guardian, Nov. 18, 2013: […] experts have warned […] a sudden loss of coolant water or another earthquake could cause a chain reaction and release huge quantities of radiation into the atmosphere. […] “After the explosion, one big challenge was to deal with the spent fuel pool because if the water evaporated it would cause a  radioactive cloud stretching all the way to Tokyo, which would have to  be evacuated,” Yuichi Okamura, deputy manager of the water treatment department at Fukushima Daiichi, told the Guardian on Monday.

    OH. MY. GOD.

  • We Not They Finally

    Will cross-check on strength of earthquake. The USGS has been downgrading earthquakes, apparently, for a long time. Dutchsinse first picked up on that one. So this last one at 7.5 wound up being called 6.8.

    Also, was this AT Fukushima or how far away?

    • mairs mairs

      USGS: Seismologists indicate the size of an earthquake in units of magnitude. There are many different ways that magnitude is measured from seismograms because each method only works over a limited range of magnitudes and with different types of seismometers. Some methods are based on body waves (which travel deep within the structure of the earth), some based on surface waves (which primarily travel along the uppermost layers of the earth), and some based on completely different methodologies. However, all of the methods are designed to agree well over the range of magnitudes where they are reliable.

      • mairs mairs

        Continued: Preliminary magnitudes based on incomplete but available data are sometimes estimated and reported. For example, the Tsunami Centers will calculate a preliminary magnitude and location for an event as soon as sufficient data is available to make an estimate. In this case, time is of the essence in order to broadcast a warning if tsunami waves are likely to be generated by the event. Such preliminary magnitudes, which may be off by one-half magnitude unit or more, are sufficient for the purpose at hand, and are superseded by more exact estimates of magnitude as more data become available.

        • mairs mairs

          Finish: Earthquake magnitude is a logarithmic measure of earthquake size. In simple terms, this means that at the same distance from the earthquake, the shaking will be 10 times as large during a magnitude 5 earthquake as during a magnitude 4 earthquake. The total amount of energy released by the earthquake, however, goes up by a factor of 32.

    I hear the big one is coming in November. Oh wait, that's this month.

    What TEPCO is really doing

    Look into my eyes:

    You only see reactor #4:

    You do not notice reactors #1-#3 and what they are continually doing to the Pacific Ocean:

    You are not concerned about where the corium is:

    At the count of 3 you will wake up feeling no concern and go back to watching Dancing With The Stars

    • Crash2Parties Crash2Parties

      I only see reactor #4. There is only one reactor. Leah Remini was unfairly judged.

      …wait..what? Oh, NICE TRY!

      What really bugs me is that it's not just TEPCO. Both the Japanese government and that of the US of A seem complicit. Where'd our amazing ex-Cold War global nuclear detection & tracking network disappear to? Not that silly cartoon version, RadNet; the other one that you can find numbers from in pre-3/11 scientific papers and media reports…

      And yes, I had to do a web search for the Dancing with the Stars reference as we don't have cable, by choice. 🙂

    Seems like hardly a day goes by without a quake in Japan. Great place to build a reactor, and the best place by far to be performing nuclear surgery.

    Unit 4 hoax is underway:

    The other side of the story on Unit 4:

    • Grampybone Grampybone

      I remember reading some of your work that already stated that Tokyo should be evacuated. The orders from the white house 3/11/12 told the Pentagon regarding American's living within a 250km radius should be evacuate. Ordered to stand down that order by the executive branch. A great betrayal of the American people has already happened. The truth about Unit 4 is that it's already had a nuclear fire and a real damage measurement is not happening.

    "The big danger is water suddenly draining from Fukushima Unit 4 pool after quake"

    This is on the assumption..that the SFP Unit 4..holds water..
    Which it doesn't…
    The problem is more likely an increase of groundwater..involving the whole plant.

  • ftlt

    This happened yesterday – midday USA PST… Thought everyone knew, so didn't post it up…

    How did the assembly removal go yesterday??? Any success???

    • Crash2Parties Crash2Parties

      Isn't the Internet amazing? You can keep up with the news halfway around the world in near real time.

      Except, of course, when corporations and governments are involved and actively don't want you to know what's going on b/c it might make them look bad, that is.

      It's all about priorities. For example:

      Associated Press
      Dateline Tuesday Nov 19, 2013 Tokyo

      "New U.S. Ambassador to Japan Caroline Kennedy talks with Emperor Akihito, second left, after presenting her credentials to the emperor as Japanese Foreign Minister Fumio Kishida […] at the Imperial Palace in Tokyo Tuesday."

  • myau

    Just saying after "crash2parties" report, if I were C.K.'s personal physician, she should be sipping nascent iodine with added liquid zeolite. Anther dose of Boron with lunch, always carry an umbrella on rainy days,etc. Hey, she may be our next president! Thanks.

  • myau

    Oh,don't forget those heavy face mask too. Even better preventive measure, she will be the 1st Ambassador who commutes btw Tokyo and DC!! Thanks.
    ps. humor aside, hope she can bestow real pressure on jap/gov to forgo the "hoax" show at R4 SFP, and accelerate the permanent wall construction all around the plant to save the ocean as a priority!!! Thanks.
