    On April 9, 2012, within a comment to a thread on WUWT Piers Corbyn forecasted for “the present period (~8-10th)” major quakes to be expected due to a large coronary hole. Whatever his methods are, I’m inclined to consider this forecast as being confirmed by mother nature.

    Piers Corbyn (@Piers_Corbyn) says:

    Many points here brilliantly put, and thanks as always, Willis.

    Two Thoughts from me:

    => Politely ask all the co-authors of this Nature paper if they were really aware of what they put their names too (preferably via someone who knows them).

    => Could the Gentlemen of Nature show us bursts in CO2 levels which precede solar events such as the large Coronal hole at the centre of the solar disc today (April 9th) as forecast – and which is a driver of weather and likely earthquake events?! See pic of
    Large Coronal Hole heading for center of Suns disc today as we warned: http://spaceweather.com/archive.php?day=09&month=04&year=2012&view=view
    and our forecast which apart from weather events also says Major Quakes are likely to come in the present period (~8-10th) as a consequence of this coronal hole and related solar events

  6. omanuel says:

    Yes, Hugo, Piers Corbyn’s forecasts are being confirmed, while those of Al Gore, the UN’s IPCC, the US NAS and the UK’s RS are being discredited!

    Why? After witnessing Hiroshima’s destruction, World leaders foolishly decided to obscure the role of (E = mc^2) in astronomy, astrophysics, climatology, cosmology, nuclear, particle, planetary, seismology, and solar physics.

    http://omanuel.wordpress.com/about/

    Now society desperately needs to identify a leader who is capable of restoring integrity to science, rights of citizens and citizen control of government, without reviving racism, retaliation, and/or the threat of nuclear warfare.

  7. Bone Idle says:

    Minor Tsunamis are being reported. 31cm in Pulau Weh (Sabang) Off the coast of Banda Aceh Sumatra. 35 cm tsunami wave at Padang central west Sumatra. 10 cm wave at Phang Nga Thailand.
    Tsunami wave up to 1 metre expected to hit Sri Lanka in a few hours.

    Let’s hope we don’t get a largish quake around Fukashima. The plant 4 building is unstable. It holds over 1500 used fuel rods in tanks. The tanks are on the 5th floor – 35 metres up.
    If the tanks rupture and the fuel rods catch fire….well in the words of one Japanese nuclear engineer…. that’s the end.

  8. KevinM says:

    “With Tsunami Warming!”

    Its not thermodynamics, its geology. Or is geology just an arbitrarily long look at thermodynamics?

    When the electromagnetic field changes, gravity being part of such a field, also changes (as in every induction electric motor, when moving from one stator field to the next one, generating force, work, gravity)
    Gravity changes before Japan´s earthquake:

  13. George says:

    “Depth 33 km” That is pretty deep in the crust, I doubt we are going to see much in the form of a tsunami. The quake occurred well to the West of the subduction fault so there wouldn’t be much in the way of thrust movement. This was likely a fairly large piece of deep ocean crust fracturing as it begins to turn downward into the subduction zone.

  14. George says:

    busted italic someplace?

    [Yes, fixed. Thanks. Once, long ago, WordPress had a bug where unclosed HTML would carry over from comment to comment and even into postings. Looks like in their latest changes that bug has returned… In this case a typo in the close (instead of slash-i it was i-blank-slash) didn’t get an auto-close put in. -E.M.Smith]

  15. George says:

    Ok, this was a “strike/slip” quake, not a subduction quake. There won’t be much in the way of tsunami. http://earthquake.usgs.gov/earthquakes/eventpage/usc000905e#summary

  16. E.M.Smith says:

    I wonder if the prior 9ish near the surface is just having a ‘propagate deeper’ reflected here? If the surface had to move a whole bunch then, stuff deeper down eventually has to adjust, no?

    At any rate, things are moving. The USGS quakes / year chart shows more recently as opposed to a few decades back.

    http://earthquake.usgs.gov/earthquakes/eqarchives/year/eqstats.php

    4.0-4.9 peaks in 2007, as does the 8+, but the energy moves to medium large quakes recently. 2011 has the peak of 5.0 to 6.9 (with 4.0-4.9 almost a tie with 2007 and with 7.0-7.9 higher in 2010, but not by much). As we just had 2 in the 8+ range and “the year is young”, we can likely get close to that 2007 number pretty easy.

    So is it just random patterns? Don’t know. It looks like a move away from lower energy toward higher energy, but could just be statistical quirks. It’s a decade scale sample of things that move on century scale processes. That’s going to have significant random walk to it.

    There’s an interesting ‘interactive’ quake map here:

    http://earthquake.usgs.gov/earthquakes/map/

  17. adolfogiurfa says:

    @E.M.: Clearly you have not experienced many quakes. There are two types: One, like Sumatra today, where the movement is predominantly Horizontal and the other, as the 2004 quake, which are Vertical and produces Tsunamis. There is a third type, involving both movements: These are the worst.

  18. adolfogiurfa says:

    @E.M. I have just seen the link you gave: What the heck do they mean by “Download Earthquakes”???? :-)

  19. E.M.Smith says:

    @Adolfo:

    Um, searching the page I can only find “Download Earthquakes” in your question, so I don’t think I said it, and can’t explain it. I did point to a USGS page where you can get the history of quake size by year, and another one where you can have a ‘interactive map’ that lets you set bounds and limits on what you want to see. Are those what you are talking about?

  20. E.M.Smith says:

    Ah, found it: The “download earthquakes’ button on the interactive map. It lets you download a CSV (comma separated values) spreadsheet of the earthquake data so that you can play with it yourself. It ought to say “Download Earthquake Data File” ;-)

  21. E.M.Smith says:

    Mexico picked up a 6.5 and there was a 5.9 in the Cascadia area.

    Looking at the N. Hemisphere view we once again see a 180 degree opposite quake in the Mexico / Sumatra set. Hmmm…..

    That part in the link ….html
    has to be added, I think. Why it doesn’t come thru is beyond my pay grade.

    [ I turned the penultimate three dots into Percentsign46 and that fixed it.
    http://www.fileformat.info/info/unicode/char/002e/index.htm
    As to ‘why’:
    “Why? Don’t ask why. Down that path lies insanity and ruin. -E.M.Smith”
    Exploring why… it’s because there is a disconnect between what is allowed in a URL and what WordPress can autoconvert into HTLM tagged stuff. Folks tend to use a lot of ‘reserved characters’ like the three dots that also have a syntax meaning of ‘tag next’ so the . then html, so the first dot gets stolen to say “tag” and then it doesn’t get one, it gets another dot, and gives up, just printing more dots and the html text that is no longer part of the URL or ‘special’ as that conversion gave up… BUT, if it sees prct46, it knows it’s a text dot, not a special char to say ‘tag next’ and just skips over it as a simple text character, then the final dot and html can be properly seen and converted to a type tag. Got it? So does this mean I get paid more? ;-) -E.M.Smith ]

    Once every 2,000 years or so, it happens a change: Can origin of the 2400-year cycle of solar activity be caused by solar inertial motion? Ivanka Charvatova
    So the supercyclic rise is a very long process, maybe a 1000- or a 2000-cycle or even longer. The Sun seems to be much more irregular than we ever have imagined..
    Timo Niroma
    http://www.kolumbus.fi/tilmari/some200.htm
    In fact, could the dominant 2,500-year cycle in the Castile Formation be related to the dominant 2,000-year cycle in the 14C spectrum (Hallstadtzeit Cycle; fig. 2B)?
    http://pubs.usgs.gov/fs/fs-0095-00/fs-0095-00.pdf
    In an electric induction motor it happens a change whensoever the armature rotates to the next stator field: …each pulse moves the rotor on to the next pair of actuated poles.
    http://www.animations.physics.unsw.edu.au/jw/electricmotors.html#three
    Perhaps the polarity change, seemingly difficult during this solar cycle, could be originated by the almost simultaneous polarity change of the whole solar system, where it arises some chaotic behavior in the mean time ( a “minimum”?).

    So, were you talking about this?:

    http://www.maltmadness.com/l110-119-whisky-tasting-notes.html

    Around midnight, Serge (and his lovely wife Fréderique who’ve had to put up with a bunch of drunken maniacs all night) had to leave due to parental responsibilities. It was sad to see them go, but I’m quite sure we’ll meet again soon. Before he left, I got the chance to hand Serge (and the other maniacs) the Malt Maniacs Basic Survival Kit, consisting of two ‘proper’ crystal nosing glasses (66cl Cognac bowls) and a blank Black Book.

    @Adolfo:

    Well, plot of the two series and see if they sync, or not… First step of discovery is ‘compare and contrast’ then looking for correlations to chase…

    Yep, three >6.0 shakers today. Good for the average.

  34. E.M.Smith says:

    The California map is over 400 total now. Looking at the N. America map, it’s almost a solid line of quake squares from down near Panama all the way to the bottom edge of Cascadia (then picking up again in Alaska). On the other side of the pacific, we’ve got loads of quake markers all around that edge. Only the Cascadia is suspiciously quiet, but even that has ended at the southern edge.

    I have no scientific basis at all for my assessment, but it sure looks to me like stress moving everywhere BUT Cascadia and the energy building up there. Starting to weaken at the lower edge. California is having reasonable ‘creep’ from the Mexico border up to about San Jose ( it looks a bit locked above that up to about Eureka, but with some volcanic quakes at The Geysers area and nearby and with some creaking on the Hayward / Caliveras / Rodgers side (that is due for a Great Quake sometime not too many decades away).

    I’m not liking the way this is looking. Especially that line of big yellow squares along the Pacific edge of Mexico, then going quiet at California. Stress redistributed northward. Now what’s it up to?…

    I’d guess settling in for a few months, then a 6+ to 7ish somewhere between LA and Seattle. Out at sea would be nice ;-)
