Looks to me like it’s on the intersection of the Pacific plate and the Australian plate, so just more evidence of the Pacific plate being actively subducted right now. Interesting set of aftershocks, too.

As I live in California, it makes it easier for me if I keep them in the list where I can see what’s shaking near me.

    Thanks for the interesting new information.

    The rapidly crumbling story of global warming from CO2 seems to have increased the public’s sensitivity worldwide to all of the natural changes that occur every day in our environment.

    That may be one of few benefits from the AGW fiasco.

    Increased accountability of research grant expenditures may be another, if Western economies still have money left to support research the AGW scare has vanished.

    All is well,
    Oliver

    And the Hawthorne swarm continues. Drove through that area today. Rained from about Lee Vining to Benton. Nice double rainbow over Mono Lake a little before sunset.

    I wonder if these quakes have a volcanic origin?

    It looks to me like we’re getting more swarms in volcanic areas…

    Noticed a red spot just a bit further south on the fault line too. Hope this isn’t a trend headed toward New Zealand again…

    Not surprised that the RFRC (-;Ring of Fire Rupture Clock;-) bypassed the US West Coast and South America’s Pacific Coast and instead let a Big One rip near the Kiwi’s once again. But I still think that we’re coming due to pay the Piper in our Pacific Northwest and another 7+ is building between Seattle and Los Angeles. I don’t have a horse in this race, quite the opposite, someone very close to me is smack dap in the wrong place these days.

    O.T. Nabro impact underestimated?

    As for the quake off the French coast, this is quite unique.
    Friends of mine doing research in the region as they planned to buy a property in the South of France also had a look at the quake history of the region and told me it was practically quake free.

    @Boballab:

    That’s the same area as the 9.x so will likely be classed as an ‘aftershock’, but a big one…

    @Interesting connections:

    And I heard that Australia had grounded some plains again due to ash…
