    Just had a scarey little earthquake

    Felt like a 3.8 or so. Came in from the east. Hope this isn't a prelude to anything worse!

    Hopefully that's the extent of it.

    Looks like it was a 4.2 in the Bay.

    Get those here all the time, due to proximity to the New Madrid Fault, which will produce The Big One in a few years, according to the experts.

    Darn it! I was logged out, shut down and in bed when this happened, but as I have a dread of being buried in rubble and burned to death I can't get back to sleep!

    At times like these just think of Betty. She had no apprehensions about being buried by Rubble.

    Hopefully no aftershocks.

    Rest, my friend.

    Oh geez, it's been "a few years" for decades. Of course you gotta have respect for a fault line that can produce an earthquake in Tennessee that'll ring church bells in Boston, Mass. and permanently change the path of the Mississippi River.

    Biggest - earthquake - ever (in the contiguous US, sorry CA, you get the most, we get the biggest. )

    I know. But it seems we're overdue.

    Meanwhile it's interesting to visit the New Madrid area and see Reelfoot, etc, and all the other post-quake artifacts.

    I don't trust Crowley's Ridge. Prime suspect to me.

    But after exploring where the mighty Mississip used to run, one can relax and enjoy a great meal (and throwed rolls) at Lambert's.

    Then what a relief it is when traveling north, to finally go up Crowley's Ridge on I55 into the Missouri eastern Ozark up-country.

    As it is part of an ATM idea I can't elaborate why I expected a reaction in this area

    Not to be cynical but we're so overdue for all sorts of catastrophes: super-large meteor strike, Yellowstone volcanic explosion, the "Big One" either in CA and/or New Madrid, an ice age, etc.

    But then that means eventually something should happen.

    Not to dis you, I'm expecting it too, its just that "we're overdue" in my opinion is starting to get a bit overused.

    No, you just want to imply that you did expect a reaction in this area probably because of particular aspects of completely unproven "hyper dimensional design". Stop it. This is not the place to promote your ATM beliefs. You know where that belongs. You're not ignorant.

    Just to clear one on the list, I don't think Yellowstone should be on it. They've been sending friendly reminders, but no overdue notices.

    As near as I can tell, the linear interpolation of dates (I know) doesn't fall until after the next ice age.

    Good point. I was working off the memory of the 7" rapid rise the caldera floor did for 2004 to 2006 leading some to claim it was imminent.

    I believe you can add Mount Rainier to the "overdue" list--as, apparently, is a giant, catastrophic slip of the faultline offshore. Seattle, which gets very few earthquakes by my standards (I grew up in LA), is overdue for quite a lot. I'm still not moving; where would I go?

    No this has nothing to do with HDDesign, it has everything to do with an imbalance of mass in the solid outer crust, which makes the rift Valley and the US East coast area 'cooperative areas' in the 'reballancing efforts' of the solid outer crust due to the centrifugal forces of a rotating sphere.

    This weeks quakes in the Rift valley in combination with the tremors in Jan Mayen region made me expect a reaction at the east coast. Although maybe atm, it has nothing to do with the HDDesign research

    Take it to ATM. This is not the ATM forum. This is still not the place to promote your ATM beliefs.

    No, better, take it to some geology forum. Thanks.

    So, anyway... I slept through the 4.2. (T-shirt slogan?)

    It was fairly unfelt in my area according to the USGS shake map.

    I awoke, normally, about a half-hour after. Sorry I missed it. I like earthquakes -- at least the ones that don't kill.

    That's pretty small for around here. But, I heard it reported on the national news services, so I had to dash off email to the folks back east assuring them I was well. I wonder if there's a definite Richter-scale cut-off for making it into national broadcasts. Nah, it probably just depends on what other news is happening.

    Richter scale is a more or less measure of absolute magnitude, at the source, so its effects diminish with distance and other factors. A 4.2 can feel like a 3.8, or if you're right on top of it, it can "feel" like a 7.0. So, the damage depends upon what's nearby, and that determines some of the publicity too.

    The Mercalli Scale is an attempt to measure earthquake "feel".

    I agree that it is a good idea to bring that up here, however, I should point out that when we are talking about, say, volcanoes, the events (eruptions, or even days without eruptions) are not independent events. Therefore, in that situation the gambler's fallacy doesn't completely apply.

    This is why geologists measure tilt and deformation, in addition to earthquakes and gas emissions. They are monitoring changes under the volcano in the hopes of identifying upcoming eruptions.

    There are deformation graphs and such on various sites, such as

    Long Valley

    Hawaii

    Yellowstone

    Now, a volcano like Rainier... it is seismically quiet, so no immediate danger of eruption (although landslides are possible at any time) but almost certainly the volcano will erupt again some day -- maybe in a year, or ten, or a hundred, or more. In a case like that, the probably of an eruption in, say, 2008, could be considered independent of the probability of eruption in, say, 2007. Although, once the volcano starts to act up, then that changes everything.

    Oh yeah. It's the first description applied to news of a quake, except maybe for event time. If the reporter doesn't have an official number to quote, she'll offer a seat-of-the-pants estimate -- from the Abowta scale.

    In my experience, an earthquake quickly is assigned an official Richter scale number, less useful though it may be -- it's tradition -- and that must have some influence on whether news of it makes it onto the air. "You got any major bombings in the Mideast? No? OK, guess we'll go with this 4.2..."

    Never ever have I heard a Mercalli-scale number in news of a minor nuisance quake. Those more fascinating numbers get saved for the post-major-quake analysis news, when the talking heads are trying to fill up a half-hour of Special Report.

    True. Yeah, I admit succumbing to the temptation of saying we were overdue for it. In my quick reading I thought I had seen reports of overdue events that were entirely independent of history. In a more leisurely recent reading, I see none. Sorry. But, yeah, hey, it is always worth a review even if not especially apropos.

    Time to rock and roll!
    As a native Californian, felt it - small jostle followed by a stronger shake - decided it must have been close (shaking was sharp, distant quakes are more rolling in action) but likely only ~4.something - then went back to sleep...

    As far as natural disasters go, I think that earthquakes are one of the least fearful because one cannot know when they will occur and they are over quickly - if you feel one happening and you are still alive - you're good til the next one!
    (although I do recall hearing a compelling personal story from the great Alaskan earthquake of 1964. That quake lasted for ~Four minutes - one of the survivors said that as the shaking continued and continued - they decided that the world was truely ending and just went along for the ride.)

    OK, replace "We're overdue." with "It will probably happen again some day."

    Meanwhile, I'm very glad my HIL (hyperdimensional ignore list) is still working just fine.

    There ya go.

    Two earthquakes have happened near enough to me that they could be felt. I was asleep both times.

    Fourth offense. He can thank my good mood it wasn't permanent.

    Cool, cool I guessed as much but the suddeness was still a little breathtaking.

    Weirdest effect of this little event, apparently a nest of ants were disturbed under my apartment and came up through my floor en masse under my bed. Fortunately they are Argentine ants, part of the Bay Area super colony and are one of the more human friendly species. Annoying only as a presence, not a biting or stinging species (to humans). I got to sleep at about 6:30am and noticed the invasion at about 8. (I was chatting here until waaaay past my bed time.) Had to finish sleeping on the couch, then dealt with them this afternoon.

    Double Secret Probation? I thought my friends made that up in College when we were caught drinking in the freshman dorm.


    darn, now I have to rethink my life.


    - oh, and sorry to read about the earthquake and inability to sleep. I like Texas; when the earth moves it's somewhere else.

    It's likely your friends got the phrase from Animal House.
