Quakes Around The World And Me

We just had a 4.x near me. This is a documentary ‘quick post’ that contains mostly static image captures; as I’m juggling a bunch of things right now.

What struck me was the interesting pattern of red “this hour” spots around the planet. Looking at some of the blue “today” quakes gives an even more interesting pattern. Like things getting compressed everywhere in a ring around the planet.

I’m about 10 miles from the epicenter of this one. I note that it is on the Calaveras fault system (where I’ve been repeatedly talking about worry that one would show up…) and has been one sharp event. That is often what a pre-shock feels like. So I’m prepping for this to not be ‘over’ but to be the beginning. (If it is just ‘one and done’ the prep is a good practice drill).

I note also that there is a 3.0 near Mammoth Mountain. A bit larger than I like to see there, but I’d expect a ‘few’ 4.x to 5.x before anything major might happen:

And check out the times of those blue spots south of Africa that ‘balance’ the red spot on the other side of the hemisphere in Tonga… I just missed red there too by a few hours…

So that would make 4-5 quakes spread around in ‘sets’ in opposition.

Interesting…

Still of interest would be checking the date stamps on those OTHER blue spots in each hemisphere to see if they are ‘recent’… but right now I’ve got to deal with the real world… (nothing quake related).

All in all that’s quite an interesting “ring of quakes” in the last 24 or so hours.

(It would be interesting to plot the lunar position relative to each point when it ‘went’, but I don’t have the time to do it… hint hint… )

Honorable Mention

There were two 4.x quakes down in Baja that show up as a symmetry of sorts with the one near me. (Each end of the San Andreas, sort of, but with each “off to the side” in an odd sort of way…)

  1. P.G. Sharrow says:

    4.1 is at least loud enough to hear, Glad to hear that you are having fun. The area from San Jose to Parkfield has been busy, no worries. Bodaga Bay to Cresent City very quiet while the Coast Range is being compressed. The San Andras crossing of the Tehachapis appears to me to be the spot of the most strain.

  2. E.M.Smith says:

    We heard and felt it. Rattled things a mite…

    If it’s a ‘foreshock’ on the Calaveras, I’m hoping the main shock is further ‘upstream’ as given how much this one shook things a 7.x would be worse for me than Loma Prieta was…

  3. George says:

    I am not going to worry until we get one or more 5.x quakes. That seems to be what generally happens before large 7+ quakes. In fact there were two such quakes before Loma Prieta.

    This is what has been concerning me most about the Southern San Andreas south of San Bernardino. We have seen a few 5.x quakes down there recently. Until we see something in the 5 range up here, I am not going to get all that worried about it.

    But when we get a 5.x and particularly a second one, that is when I am going to be seriously concerned. Note that there are generally one or more 5.x quakes preceding a 7+ but even a quake in the high 6 range can be damaging. The Northridge quake was a 6.7 and did a lot of damage.

    There had been damaging earthquakes in SF before the 1906 quakes:

    http://travel.webshots.com/album/575495065gkKXqE

    “In the 83 years prior to the 1906 quake, seven damaging earthquakes of magnitude 6.5 or greater occurred. Only two have occurred since the San Francisco earthquake. Several 5.0-plus seismic events in the two years preceding Loma Prieta also served as warnings. ”

    The above from http://www.consrv.ca.gov/cgs/News/Pages/loma_prieta.aspx

    A 5 doesn’t really release that much energy and are mostly stuff “cracking” under the surface. When we start seeing magnitude 5 quakes, I might just be outta here.

  4. E.M.Smith says:

    @George:

    I agree.

    1s and 2s tell me everything is fine.

    3s tell me it’s OK, but think about watching.

    4s tell me it’s time to watch, as something interesting could be coming and you’d not want to miss it.

    A 5 tells me “Watch. Now might be good.” 2 or 3 of mag. 5 and I’m a bit worrked and doing active prep and / or suggesting a bit of a road trip ;-)

    A 6 means it’s time to be in Texas or Florida for a while, if possible, or pack the glassware in crumpled paper if you can’t. Double check the water barrels and make sure the cars are full of fuel and parked on the street (not under a tree) with ‘bugout bags’ in the back. (If I havn’t already done that after the second 5.x in a row…)

    Then there is a 7+. Time to break out the BBQ, fire up the generator, and practice those camping skills….

    We won’t talk about an 8…

    FWIW, I usually don’t bother with any posting about anything under a 6. Just in this case there was that rather odd symmetry all over the planet…

  5. George says:

    5s are the scary ones for me, unless they are aftershocks, and depending on the fault they are on. Seeing 5s on a long fault capable of a 7+ gets me nervous, particularly when there hasn’t been much activity. The 6.0 in 2004 in Parkfield is worrisome. We generally have a 7+ quake within several years of a 6 at Parkfield.

  6. E.M.Smith says:

    Looks like Pakistan just took a 7.2 Quake a couple of hours ago.

    Posting “soon”.
