Fears Grow that Japan Could be Hit by Another Powerful Earthquake

Concerns are rising that Japan could be hit by another massive earthquake after a magnitude-7.3 quake struck off the coast of northeastern Japan on Friday. [...]

Japan’s Asahi Shimbun reports that aftershocks could continue and warned residents in the northeastern region to exercise caution.

Japan’s Defense Science and Technology Institute says the latest tremor is especially alarming, adding an earthquake with a magnitude of eight or over could soon strike the country.

Title: Dec. 7 quake: larger aftershocks possible
Date: December 08, 2012

The magnitude-7.3 temblor that rocked northeastern Japan on Dec. 7 is now considered an aftershock of last year’s Great East Japan Earthquake–and it may not be the last.

At least one expert has warned of a potentially larger temblor still to come.

“The 2011 magnitude-9.0 earthquake could be followed by a magnitude-8 aftershock,” said Yoshimitsu Okada, president of the National Research Institute for Earth Science and Disaster Prevention. “The Dec. 7 event should be taken as a warning for that.” [...]

The Dec. 7 earthquake arose from what is known as a “normal-fault” mechanism [...]

Parts of the crust in the “outer rise,” a topographical protuberance farther off the coast from the plate boundary, were under this tensile stress when they slipped Dec. 7. [...]

A normal-fault earthquake in the outer rise carries a high tsunami risk. [...] The tsunami risk remains even if the seismic source happens to be far from land. [...]

Giant earthquakes of magnitude 8 or greater may involve ground movement of long oscillation periods, causing high-rise buildings to sway, experts say.

The Japan Meteorological Agency has called for continued vigilance.

    "… a magnitude of eight or over could soon strike the country"

    So when seismologists say "soon," what sort of time-scale do they typically have in mind? Days? Weeks? Months, or even years?

    … months, not years, certainly not decades …

    … no General Electric rapid response team from "Reactor Malfunction" in case of "Poor Quality Design and Manufacturing" division of "world class company" General Electric in sight ????

      History tells us in the past 100 years Japan has experienced 8 of the 79 earthquakes worldwide measured at 8.0 or greater.

      Not all were east coast Japan.

      There was a 35 year interval from the 1968 east coast Honshu earthquake to the next one in 2003 Hokkaido.

      What does this tell us? 8.0 or greater earthquakes in the Japan coast areas happen more often than anywhere else in the world.

      Which makes it an insane idea to build and run dangerous toxic chemical plants that upon rupture are dangerous to humans over a wide area for centuries. The economic losses are beyond calculation. Many trillions just in the first 50 years for health and real estate losses.

      The widely varying time between large Japanese earthquakes also tells us scientists are NOT able to accurately predict when or where a large 8.0 earthquake will occur. They can only guess based on the range of intervals of past earthquakes. So that is not science… just statistical guesses.

    So few people read this site, which is rather astounding given the direness of the event and the importance of the information provided.

    Applying iodine tincture topically in the vicinity of the thyroid or at the sides of the neck can be beneficial to thyroid health in the presence of the isotopes.

    Now Japan has to upgrade safety specs for nuclear plants to cover 9.0 quakes and 50' tsunamis. Let alone building 6 reactors on one site that endangers any one or all of the six during a crisis.

    Worry about where to store the spent fuel safely for generations on a quake prone island later.

    No 'off' switch when using nuclear power.

    The Timeline for a Magnitude 8+ quake, would be

    1) Maginutde 8+ Quake close in to Japan.

    2) NHK/Japan times twitters Quake Warning.

    3) Quake Hits.

    4) Damage reports.

    5) All nuclear power plants report as healthy.

    6) US DoD launches multiple aerial assets to assess issues.

    7) Tepco announces all plants are healthy.

    8) US NRC Spools up Emergency Ops Center, including key manufacturing staff.

    9) NHK Announces no worries at nuclear plant.

    10) US DoD removes dependents and critical assets.

    11) Tepco announces minor issues but all plants are fine.

    12) NHK FIlms IAEA/NRC/NISA inspectors in tyvek bunny suits giving thumbs up.

    13) Japanese govt states no evacuation is needed.

    14) First reactor explodes.

    15) Foreign nationals evacuated.

    16) Japanese govt recommends 2 KM Evacuation.

    17) DoD civilians find reasons to attend conferences in Korea or hawaii.

    18) More reactors explode.

    19)NISA suggests 10 KM Evac.

    20) All foreigners leave Japan.

    21) Okinowa becomes favorite destination for japanese elite.

    22) NISA says all is well.

    add additional steps if you see fit

      Additional steps:

      3.1) (if quake strikes close to northeast coast) SFP #4 structure is further stressed–even if it remains standing, cracks widen; pool becomes incapable of holding water. Water starts to drain …

      4.1) SFP water level getting lower.

      5.1) Locals who follow trustworthy alternative news sources prepare to evacuate

      7.) Locals who follow reliable alternative news sources are en route to south/west (or abroad)

      10.1) SFP water level getting lower.

      13.1) Fires start …

        Alternative timeline

        -10) Dec. 7, 2012, 7.3 earthquake serves as wake-up call to Japanese government

        -9) Global nuclear industry recognizes that a worse case scenario earthquake fatally compromising SFP #3 or #4 structure would pose a fatal threat to THEIR INDUSTRY

        -8) Japanese government, U.S government, other nuclear nations, and global leaders in nuke industry pool their resources to dramatically accelerate spent fuel removal process for SFP #4

        -7) Japanese government, U.S government, other nuclear nations, and global leaders in nuke industry pool their resources to dramatically accelerate spent fuel removal process for SFP #3

        -6) fuel is safely removed in a timely fashion

        -5) spent fuel is safely secured in dry casks

        -4) threat posed by steps 3.1 and 4.1 is averted.

        -3) 13.1 can't happen because fuel has been removed in time

        -2) 5.1 doesn't need to happen

        -1) 7.1 doesn't need to happen

        0) other nuke plants are kept shut down; earthquake/tsunami threat isn't compounded by additional threat of further nuclear disaster(s)

        Unfortunately, this alternative timeline would probably only be possible in an alternative universe in which some type of beings other than HUMAN beings are in charge. Human beings are too short-sighted and selfish to make it a reality.

    WHERE IS HE. the man who was talked about that initiated the earthquake formula and could predict earthquakes a few days before they happened

      WHERE IS HE [the man or woman who predicts the time of an earthquake]?

      SP: As I said in another thread… Drilling multiple monitoring wells along faults might offer early warning although how much time ahead is not known.

      Gutenberg and Richter invented the formula for frequency and magnitude. Others have tried to narrow down the distribution factor (which once again falls into the statistical realm).

      Trying to make sense out of "facts" modern seismologists profess to know is debatable to me. Witness this analytical treatise:


      Understanding their math is beyond my grasp. When one of them predicts a month ahead of time (or even a day) the exact hour of a large earthquake I will kneel in awe to their brain power.

      Color me skeptical…I don't plan on buying a knee cushion in my lifetime.

    Does it need to be an 8 to remove all control of a nuke plant?
    What about an inland quake, one that's shallow, along one of the faults right under one of the plants?

    Even with backup power, much depends upon….plumbing!
    I'm afraid the focus on big quakes helps shield the reality of how dangerously sited some nuke plants are.
    It doesn't take a tsunami,
    all it takes is pipe whammy.
    It doesn't take loss of power,
    just water lost for some hours.

    Much-too-much credit has been attached to design and engineering and safety and all the rest, when they've just had pure dumb luck so far, Fuku notwithstanding.

      The problem is that they "assume" right from the start that the worst case scenario is impossible.

      They assume a total meltdown with breach of containment is impossible.

      They assume more than a tiny percentage of fuel melt is impossible.

      If it's impossible to come up with a viable solution to a crisis scenario, just assume that scenario is itself impossible and leave it out of your calculations. It makes risk assessment and emergency planning so much easier.

    Talk about fate intervening in the affairs of government in Japan. Just as the nuclear issue was successfully being buried, the Earth's surface comes along with a short but blunt campaign speech of its own. End nuclear power production in high earthquake regions first before it kills us all. The rest will fall from economic factors.

      They are creating earthquake zones everywhere with fracking. Every nuclear power plant is in your backyard. Every nuclear power plant is in an earthquake or flood zone.

    Off shore waste dumping sites hit by recent multiple earthquakes off coast of Japan

    “These dump areas have been getting alot of strikes from off shore earthquakes during the last nearly 2 years. Why doesnt anyone talk about them?
    “The areas with dark hatchings are “special” waste sites likely for nuclear and biological wastes and the larger areas for lesser hazardous waste..
    “What effects are the effected dumps having on the sea life in the areas?
    “How much damage to the seabed is occurring near these off shore dumps?…”
