Quake – 6.6 Near Japan

Off the coast of the southern island of Japan, we have a 6.6 quake. Some news shows are reporting this as a 6.9 but I’ll go with USGS.

The strange thing from my point of view is that it’s in the middle of nowhere. Zooming in:

Don’t really know what to make of it, though. Far enough away from anything of interest to not cause much damage. Big enough to be interesting.

There was another 6.x in Indonesia a while back that I’d not bothered to post about, but probably worth a mention here as it’s “nearby”.

UPDATE: 30 Nov 2010

In comments, boballab posted a link to a picture of the undersea topology with volcanoes marked.

So it looks a bit less like “nothing there” and a bit more like “on a fault in the approach to the volcano rise line”. Those lateral cracks we see near spreading zones.

  1. Earth is definitely part of the Solar System, . . .
    and the parts of that system are all interconnected!

    Only yesterday PhysOrg.com reported that the University of Colorado at Boulder’s Laboratory for Atmospheric and Space Physics and NASA’s Goddard Space Flight Center in Greenbelt, Md will finally start a study of Sun’s effects on Earth’s climate!

    http://www.physorg.com/news/2010-11-cu-nasa-center-sun-effects-earth.html

    As noted at the start of my Chapter in the new book, “Slaying the Sun Dragon: Death of the Greenhouse Gas Theory”,

    Western science and Western forms of government face a self-inflicted crisis: Loss of public confidence caused by unbridled greed and selfishness and by the abuse of federal science as a tool of propaganda.

    Use Google Earth and make sure you have the Earthquakes and Volcanoes turned on under the Gallery menu. From there type in the coords and when it zooms in on that location 2 things stand out:

    1. They track and mark large old earthquakes. You will notice some 7+ quakes near that location and the more you zoom in the more smaller sized quakes nearby pop up.

    2. There is a chain of underwater volcanoes just to the east, probably where that red fault line is on the USGS map.

    Here is what I copied from it for this one (hopefully this works)

    Well that did’t work so here is the link to Tinypic where I hosted it and a second attempt using different tags:

    @Oliver K Manuel:

    Do you have a web page up with a ‘thumbnail sketch’ of the Iron Sun theory? If so, I’d like to read it. Right now I’ve got a vague idea what it’s about, but not much more than that.

    If you don’t have such a page up, I’d be willing to put up a page. There seems to be some interest in the idea and I’d rather not be talking about it from ignorance…

    @boballab:

    Google Earth is one of those things I’ve studiously avoided learning / installing in a vain effort to avoid the time sink it will bring with it. Unfortunately, the notion that it will show volcanoes and earthquakes has likely pushed me over the edge… I can feel weeks of my life about to drain away as I crawl over the surface of the earth looking at the quake and volcano correlations… Nice picture…

    I’ve added it at the bottom of the posting as an update.
    I think I need to go make a coffee mocha…

    I also find the sheer density of quakes in California a bit interesting / worrying. We’re building up a density of 2 and 3 sized quakes from Hollister toward Stockton that is looking a bit like Baja before it had a 6 sized event. They are also showing up in the ‘minor’ faults more inland than the San Andreas and Hayward / Calaveras faults. Yeah, it happens… but IIRC, we had a 5.x on one of them (near LLNL Livermore… I was on top of that one) just a bit before we had the Loma Prieta 7+ a few years back.

    No, nothing but a semi-random correlation in memory. But it had caused me to speculate that the deformation shows up first in the minor faults, then perhaps when they can’t relieve it, the major faults adjust… If there is anything to that speculation, it would imply that this might be the pattern just before the Hayward / Calaveras lets loose. The lower San Andreas moved in the Loma Prieta event, now more inland is showing stress transmission. So that stress is ending up where?…

    (The problem with this kind of ‘Quake Watching’ is that it can take a decade or two to find out if you are right. It’s a very slow process… So my speculation might be exactly right, and we could get the expected Calaveras or Hayward fault system quake in, oh, 2033 … Personally, I expect it to be a bit sooner than that. Perhaps 2015 or so. But it could be sooner…)

    At any rate, having watched these maps for quite a while now, it sure looks to me like we’ve got a bit of an increase in quakes all over the globe this year. Though concentrated in the usual active regions.

    Oh, and it looks like USGS has upgraded the Japan quake to a 6.8 in the present set of statistics:
