TIbet (China) 6.9

Just 3 days ago I’d said:

Now this is just becoming a bit much. When I have to think about it being “only” a 6.8 and not quite a 7 and maybe that has me making too many “quake” postings… something is up. So we’ve had several “7” scale and so many 5.x that they are not even worth counting. The number of 6.x has been enough that I’m looking at them thinking “eh, not a 7?”

Now we’ve got a 6.9 in Tibet in China?

Look out Kamchatka and Alaska! At this pace, you’ve got a week to prepare…

(And I very much hope this pattern is broken Real Soon Now! Because if it isn’t, we’ve got a month or so and it’s in MY back yard…)

Here is the original static image:

And just look at all the 5.x between Asia and Australia and the Pacific Plate.

California Map

Just because I’m here…

The aftershocks of the Baja quake are still working their way toward Death Valley. Eventually that Baja Rift will make Death Valley part of the Gulf of California and even add Mammoth Mountain / Long Valley Caldera to the mix, but that’s a few million years away… though we’re seeing that process move forward one baby step now.

Three days ago I said:

That “Barycenter” predictive thing seems to have some merit. Here we are in a Major Minimum with the Sun at low angular momentum and we’ve got quakes going off all over the place. Yeah, “correlation is not causality”, but…

And now I have to add: And they are happening over near where volcanos have been a major issue in past solar minimums? Not good…

And now the quakes are headed up toward Kamchatka where volcanos are already erupting and toward Redoubt in Alaska where we had renewed activity this last week…

Keep an eye on it all and hope it just fades away. The alternative is NOT something we want to be watching if at all possible. Not with things getting colder now.

Volcanos? Why not – Here Are Some Maps

I like this nice interactive global volcano map. You can click on a volcano and get a report about it.

The USGA US Volcano Status map gives a more focused look at the US action.

    So that’s going to be the buggers’ excuse? “No we weren’t wrong. It’s cold now but only because of the volcanoes.”

  2. Ken McMurtrie says:

    CO2 issues pale into insignificance, even if they were actually an issue, which they weren’t.

  3. dearieme says:

    Hello, that”volcanoes” remark might have been prescient.

  4. E.M.Smith says:

    Well, it looks like the action has moved on to the North American aside with that 4.3 near Alaska…

    And yes, it does look like I forgot about Iceland when looking at what volcano was ‘in the path’… If things are getting compressed on the Pacific Plate then they are being torn asunder on the North American / European plate boundaries… and that would imply Iceland is “ripping a new one”…

    I wonder if anyone has ever done a retrospective study on correlation between Pacific Quakes and Iceland Eruptions? They really OUGHT to go together. One side can’t expand unless the the other compresses and subducts…

    And didn’t Iceland cause a major problem with eruptions during one of the “Major Minima” like the Dalton? I know it was active near the time of “1800 and Froze To Death” (shortly after, IIRC)…

    You know, I’m getting this creepy feeling like I’ve seen this movie before…

    Iceland dumping clouds of volcanic gas and dust over Europe causing massive disruptions. Quake and volcanic activity in the Asian part of The Ring Of Fire. Solar output reduced and sunspots scarce. Followed by… dramatic cooling and crop failures… then a couple of massive wars and political instability… 540 AD or so with the fall of Rome? (Don’t know if Iceland was active then, but the Dark Ages began with something making the sky very dark…) and again in the 1800’s? What about during The French Revolution? I feel a trip to The History Section coming on…

    I really don’t want to watch that re-run…

  5. E.M.Smith says:

    Just for “grins”, here is the European Map link:


    Iceland is oddly devoid of any inkling of anything happening.

    and there was a 6.3 quake in Spain a couple of days ago on April 11th.

    ‘Fimbulvetr’ would cover it I think?


    The volcano thread at WUWT has some useful links/comments in it

  7. vjones says:

    Well, since I’m under the volcanic plume and grounded by it since airspace in Europe is closed, I have a rather different interest – getting home!

    I am looking forward to some nice sunsets, but I’d really like to get home first.

  8. E.M.Smith says:

    @Chuckles: Yeah, that about covers it!

    FWIW, in following that link and some others about the Nordic Bronze Age, I ran into this snippet:

    “The Nordic Bronze Age was characterized by a warm climate that began with a climate change circa 2700 BC (comparable to that of present-day central Germany and northern France). The warm climate permitted a relatively dense population and good farming, for example grapes were grown in Scandinavia at this time. However a small change in climate between 850 BC and 760 BC and a more radical one circa 650 BC brought in a deteriorating, wetter and colder climate (sometimes believed to have given rise to the legend of the Fimbulwinter).”

    Gee, so “climate change” was happening back in the “BC” era… and they were growing grapes in Scandinavia!

    Wonder what made it so “warm” in 2700 BC and so cold in 650 BC… Must have been all those Norse Proto-Volvos and Proto-Saabs }(8-0 or perhaps the Reindeer make more methane than we’ve been lead to believe ;-)

    }:-9 }:-9 }:-9 }:-9

  9. E.M.Smith says:

    @vjones: So, are you anywhere near Europe? Any chance of a “Eurail Home?” Something like, oh, land in Rome or Prague and take a train in?

    Yeah, slower than a jet, but a lot faster than an airport sofa…

  10. vjones says:

    @E.M. Smith, Yeah I think can get home tomorrow – about an eight hour train journey (vs 1 hour flight).

    REPLY: [ Best of luck to you! -E.M.Smith ]

  11. Chuckles says:


    It’s certainly real peaceful in North Herfordshire, nearest airliners are round Frankfurt at the moment…
    Time to hitch-hike?


    I imagine all the EuroStar trains are stuck in the tunnel cos it’s the wrong sort of dust?


    Yes, There’s some real interesting stuff on the Icelandic volcanos floating round. One throwaway was that they have produce a third of the total lava output of the last 500 years…..
    Looks like a lot of very interesting connections there. I’d imagine the CET Central England record might be useful for some?

    A useful page is here, lists all the frisky little fellows.


    The one that worries me is Katla, as it is a lot bigger than Eyjafjallajokull and is known to be influenced by it. Not in a good way either. Like 200000-400000 cu m/sec flood discharge from melting glaciers.

  12. E.M.Smith says:

    Nothing is showing on the California graph (after the windows rattled…) May need to watch the California chart for the next half hour and see what happened… (dinky near or bigger far away?). Felt like a “dinky near” – shorter pulse… but sometimes only a bit of a long wave from far away makes it. But at this point it’s looking like a ‘way dinky’ very near, as sometimes happens or some other ground / air disturbance.

    Interesting times…

    This is a bit later than what I felt… but it’s on the same fault system. Perhaps something shifted that way, paused, then…

    @Chuckles, interesting site of flight radar – I didn’t know that existed.

  14. E.M.Smith says:

    2nd that on the “flightradar”!

    Just don’t watch it on your laptop as your plane approaches New York City ;-)

    Very strange to see nothing over England, Ireland, Scandinavia… only traffic in the south / central …

  15. Chuckles says:

    Yes I found flightradar recently and filed it away in the bookmarks. Now when something from Stansted misses the roof by inches, I can establish where to shout invective with a couple of mouse clicks.
    Watching the traffic die away earlier today was quite eerie.

    Not a good feeling when you are of an engineering mindset and screens that are supposed to be full of info start going distressingly blank.

  16. Chuckles says:

    And of course, those flightradar web pages are what public/national data looks like when it is available, and properly used…..

    Now this is just getting silly… several 5.x and a 6.x per day or two, with the odd 7.x thrown in most months?

    Oh, and a volcano shutting down norther Europe air travel…

    And not too long after that monster Quake in Chile…

    Things are moving, the crust is jumping (and there was another 5.x near Australia…)

    It’s not a good time to sit at home and it’s a lousy time to be flying. Maybe a boat ride to Polynesia…

  19. vjones says:

    Well I made it home. Not too bad in the end but I think I was fortunate not to be stuck on the wrong side of the channel.

    Please check your email – I need a reply asap.

    What a beauty of a line of quakes where the North America Plate hits plate at Central America in Southern Mexico…

    I’ve saved a copy of the image for “someday”…

    AND an odd Trio of a 5 in Chile, a 5.2 575 km ENE of Perth in Australia and a 5.3 in the South Sandwich Islands… wonder if the south is getting squashed too…

I’ve been coming here for the past couple nights and reading. I just wanted to let you know that I’ve been enjoying what I have seen and I look ahead to reading more.
