Japan should be prepared for the possibility of a magnitude-10 earthquake, although the chances of a temblor that size are slim, a seismologist said.


If a temblor of such a scale should strike, the underground rupture would continue for 20 minutes to an hour, meaning tsunami could hit coasts before the shaking subsides.

If a 3,000-kilometer stretch from the Japan Trench to the Kuril-Kamchatka Trench along the Pacific Ring of Fire has a slip of 60 meters, that would constitute a magnitude-10 earthquake, [professor Toru Matsuzawa of Tohoku University] said.

The energy of a magnitude-11 quake, 30 times more powerful than a magnitude-10 temblor, would be equivalent to that of the asteroid impact that is believed to have caused the extinction of the dinosaurs 65.5 million years ago. Such a quake would cause a shift extending more than 20,000 kilometers. Matsuzawa concluded that consideration would not be needed for such an earthquake.

A magnitude-10 quake would be 32 times more powerful than the 9.0 earthquake that hit northeastern Japan in March last year.  […]

A magnitude-10 quake would occur, for example, if an 8,800-kilometer fault along a northern Pacific Rim trench shifts 20 meters.
Matsuzawa says such an earthquake would result in tremors lasting 20 minutes to one hour, and trigger days of tsunamis.

Matsuzawa stresses he’s not saying a magnitude-10 quake would definitely occur. But he notes that Japan was hit by a magnitude-9 earthquake when it had been expecting a maximum magnitude-8, so people should be aware of what could happen.

    What is he after more money for research, he is fear mingling, in modern history their has never been a 10.
    He has been reading to many comic books.

  • patb2009

    it's worthwhile to assess the risks and work up kep plans.

    of course a Magnitude 10 quake?

    Not sure what survives,i think a lot of big buildings would fall, I think the casualties would be
    fantastic to infrastructure ( No Power, Water, Sewer, Gas, Pipelines, Telecoms) in a whole region
    and If there was a tsunami?

    All bets are off.

    When Gaia gets rockin'
    with earthquakes and waves
    it could be some shockin'
    for those talkin' brave,
    as she has "reputation"
    and knows how to rave
    and no one can tell her
    "Ooh Baby -Behave!".

    When she's in the mood
    for more than moonwalkin'
    she can make moves
    that'll leave nuke-jocks gawkin'
    as she slams their plants
    and their bravery caves
    they'll be crappin' their pants
    and know they are slaves
    to her might and her power
    and no useless squawkin'
    will delay the hour
    when their plans she is mockin',
    leaving in ruin devices depraved.
    SHUT 'EM –
    before the surprise she has saved!

      One can see that you, or-well, are Gaia's offspring. Like mother, like child, full of surprises.

      • or-well

        m a x l i , Gaia slips me a little "consideration" for mentionong her name. 🙂

        • or-well

          She doesn't care that I can't spell for crap. "mentionIng"

            "MENTIONLNG" doesn't look any better than "MENTIONONG". Try again! LOL

            • or-well

              No! I might lose my allowance and have to do homework.

                While we are at spelling… The next nuclear power plant might say "Goodbye!" simply because of a little misunderstanding coming from the identical looks of the upper-case "i" and lower-case "L" in some operating manual or construction plan. We can add this to our list where already are earthquakes, tsunamis, reactor tests, plane crashes, Carrington Events, drunken staff, bush fires, floods, terrorists, sabotage, power cuts…

  • Yep they will be crappin their pants, and wondering if they can scrape up enough bucks to buy a few car batteries.

  • Yawn. It's probably about to happen. The North Pole shifted from Canada to Siberia, and it's possible to see the track it will take when it flips. But then the Earth will contract massively and the Seas will drown all the npp's….
    About a month's time after this week's second Pacific Eclipse…

    I'm still waiting for the big one to hit California/San Andreas.

    Another 5.2 just hit Miyagi, Tohoku, Japan, about 30mn ago.

  • Aye, I saw that- the stress, and future quakes, looks to be moving upto the Kurils on Infra Red..

  • @maxli – 'taint Kool Aid, 4shur…

    Started taking coffe-mate instead of milk, if the coriums are going to, keep belching..

      If you want to avoid anything coming out of a cow (because of Fuku fallout) you are not out of the woods, it seems. According to this information here:
      this stuff is marketed as "non dairy", which may be misleading. Between the ingredients you find:

      "Sodium caseinate: A milk protein that contains no lactose, stabilized to have a longer shelf life."

      Milk protein! And there are more interesting details, for instance:

      "Partially hydrogenated soybean and/or cottonseed oil: All partially hydrogenated oils contain high levels of trans fats, which are brutal to your body. These cheap, human-tweaked fats were adopted heartily by grocery manufacturers in the 1970’s, a move that some say helped to kick off the American obesity epidemic. Soybean oil is perhaps the worst, as some contend that it depresses the thyroid gland and lowers your energy level.
      However: COFFEE-MATE is legally allowed to say it is “trans fat free” because the serving size is so small. But don’t be fooled: COFFEE-MATE contains trans fats!"

      Other ingredients are made from corn or soy. I have a feeling, I read something about radioactive corn and soy in the past 20 months.

      If you want to live healthy, you can't! You can only choose between pest and cholera. I stick to old-fashioned milk.
