Hmm... Later one is slightly bigger. according to USGS. Odd. I thought it was a tad smaller.

Edited post because BerkeleyGal beat me to it with posting the USGS data page details.

Edit again: actually, having another look at the webis, the second one (posted above) did have a slightly stronger trace. My mistake. I need more coffeeee!!

So the last three was 2.6 2.7 and 2.8

If the next one is 2.9 I will freak out LOL

It was at the Basin creek farm TA.X40A. Was just a guess, because they looked like a darker spike compared to what it was doing earlier, the stations i was trying to listen to last week aren't there at the moment, or I can't find them (it's late, I might just have NO idea what i'm doing though )

Now they have just reported this one.

I reported it, and they are saying the one that make the dog get on top of me was a 2.8. That wasn't the dog that normally does that though, so it might have been coincidence this time.

Oh, okay. It could be that the scale GEE was running at the time for that station was screwed up very high in senstitivity and so you could have seen something which was being plotted in nanometres/sec rather than microns/sec, in which case it could look like quite a jolt -- even though in reality it would barely disturb a strolling ant. I've almost freaked out a couple of times watching these things until I've checked the scale and seen how incredibly small the "jolt" actually was.

Yes, we know... Just scroll up the page to BerkeleyGal's post.

(It's cool, though. Take no offence! Way better to have something important like this posted twice than for it to be missed.)

Regards,

Mike

thanks mike! I'm pretty sure it was too sensitive - what's a good range for it to be at to get an idea of a decent quake?

reply to post by bkaust

GEE's software is set up to auto-adjust the scale of the trace according to what's happening at the time. In other words, if there is only "background" ground movement, which is often only in the nm/sec or very low microns/sec range, then it'll set the scale to show even these very slight changes quite well.

At a casual glance the two traces might look the same, but in terms of actual ground movement they are quite different...

Rather than go into details here, I can recommend an excellent thread started by TrueAmerican, called GEE Tips. He explains it all very well, with details of exactly what the scales are showing and when to start getting seriously interested in them.

Best regards,

Mike

Um you did see the note in that article by the editor about Sorcha Faal?

Nuff said. Won't happen. I am sick of these scaremongering sites that have absolutely no consideration for the feelings of the people who live in the area concerned. They just think it is all some big game.

and combined with the increased volcanism around the globe

You know I have to say it! What increased volcanism is that then?

Back in the mid 1970s I did some work in Greenbrier for water/sewer improvements. I ran a level circuit from the ridge just north of Greenbrier about 2 miles south. And also level circuits around the town as it was back then. The benckmarks set probably had a precision of around 0.03ft vertical. The work extended from the south area of the quakes to a point just outside to the south.

If I could get my hands on the field notes and re-run the levels I wonder if it would show changes in elevations and deformities in the land surface.

Yeah, I'm in agreement with PuterMan on that one. The only reason I posted it was someone mentioned it, then another asked for the info. And by reading the article & looking at Ken Rings' website it is very clear that he (Ken Rings) never predicted anything for the USA, only for New Zealand.

In retrospect, I should have separated out the reply post with the article link (and listed a disclaimer it was by a known hoaxer) & the information about earth tides. I seriously do not want to come across as giving any SF story validation.

Whew! I was out for most of yesterday so I had quite a bit of reading to do this morning to catch up on this thread.
I'm posting a link that was forwarded to me two days ago in which it references the NMFZ in relation to Oklahoma. It does mention a visible fault (aerial) near Lawton, OK named Meers Fault which reportedly produced a 7.0 quake 1,600 years ago. I had not heard of this before and I've yet to do some research on it, but I will after I get done with my earthquake "proofing" chores around the house. As a side note, I have not experienced any more of the high tension headache-like pain that I had a few weeks ago that lasted 7 days. I've come to conclude it was either sensitivity to all the EQ activity in AR or quite possibly TPTB are messing with me/us using one of their many ELF towers. Aaaaaaaah, the rabbit hole has no end?

The name Sorcha Faal is yet another conspiracy in itself. I've seen it referenced many times over the last few years on certain "patriotic" blogs on which there are many delusional bloggers. Everything posted must be scrutinized with care.

Do you think you would be able to do that? That sure would be a big piece to fit into the puzzle!!! It would be a good baseline for now, even if nothing much has changed yet. Then there would be proof later for how fast it changed.

It continues to amaze me how the right people, at the right time, with the right expertise, find this site when they are need most. It can't be a coincidence! We're supposed to figure this out!

The earthquakes are now being remotely triggered by distant quakes.

It's the groundwater reacting to the siesmic waves. This causes pressure which then causes the water interact with the faults.

Scott Ausbrook has revised his ideas about how big the fault may be. He's also increased the magnitude of a larger quake to 6.

I think the fault is even longer. It runs ENE. From Guy to Greenbrier. But I think it continues to the south. If you look on a map. The fault will run under the valley to the south west of Greenbrier. It probably runs under the road, Green Valley Drive.

That's it. I can't write anymore for the moment. I'm ill. Real sick, and will need to rest.

Take care of yourselves.

The engineering firm I worked for at the time was very good at saving all the field books for surveying. I guess they would still have them, but probably boxed up in storage somewhere.

At the time I made detailed descriptions of the benchmarks and their locations. Mostly they would have been cotton spindles set in the base of power poles or trees. Many of them are probably still there as they were 35 years ago.

A cotton spindle is used in ginning cotton. It a specialized and hardened piece of steel about 6" long. Greenbrier is not in "cotton country" and I doubt there are any to be found other than the ones I used back then.

The descriptions for location would often read something like this...

Cotton spindle set 0.5 ft high in west side of 12" pine, 35ft south of the centerline of XXX street about 200 ft east of hwy 65

For those benchmarks that are still there, an identification would be certain.

Robin, is it "knowing" that's making you sick, or do you live close enough to sense the changes? You're doing the right thing by stepping back every so often to recharge! I said on here a while back, it's PETS. Pre Event Traumatic Stress. (My label).

Close your eyes, clear your mind, (as much as you are able!), picture yourself in the most calming place you can imagine, and breathe Deeply and Slowly. When we are stressed we tend to get all tense and can only breathe shallowly. Too little oxygen can cause all kinds of health problems too.

We need all of our "Guides" in order to get through this. Take care of yourself!
