Earthquake Swarm in Arkansas Intensifies. Memphis, Tennessee could be epicenter for the next big one

reply to post by Fritzthecat


this is just freaky



I edited my original response cause I had too many references to everything going on that would have sent bells and whistles setting off, and probably get me killed.

Here is the updated resource list for this thread. If you use maps and charts please provide links a well, so they can be included in this reference,

Channel 5 news had Scott Ausbrooks on there saying the fault line was twice as big as previously thought. Meanwhile I feel like the crazy person get these noises out of my ears and head

I'm in Memphis and saw that on tonight's news too; that information about the New Madrid fault has been re-evaluated to be twice as big as once thought................

First, before you read this, has anyone ever tried to run down-hill on very brittle and loose shale? You'll end-up at the bottom really fast and lucky if you don't break your neck or rear-end.

Ok, now that we have settled this issue of shale being very fragile and unstable when broken into many many pieces, please read the next few paragraphs and view the images with a very open-mind. And hopefully some renewed insight might take-hold.

So, they think Guy / Greenbrier fault is larger than previously suspected? That's something I have known my entire life. The Crowley's Ridge, L'anguille River, and Marianna area are part of it. I would even speculate that the fault zone is tied-in to the Guy Fault and other areas west.

Below, is a "rendition" of Ancient Arkansas, when much of the present state and surrounding area was flooded. By following the natural valleys and river channels, you can see where water was once directed by possibly seismic forces, considering the possibility of an ancient caldera or volcano around the Hot Springs location. I colored the sections so you can see more clearly the speculated terrain. The red lines are possible fault zones. Note the fault which is supposed to represent the Guy Zone, it is a little off, so just eye-ball it.



Then there is this image below, which is directly related to the work of Dr. Al-Shakri (sp?) of University of Arkanas at Little Rock, which hopefully represents a portion of the fault around / near Marianna, Arkansas. I know this fault to exist due to the fact that I felt an earthquake there which rivaled the recent Greenbrier quake, it might have even been stronger, back in the 1970's. Someone needs to take notice of this and really start yelling in someone's ears that can do something to study this and find-out all we can.

I think we have been warned and if we don't take note, and prepare, it will be our foolishness after the fact, if something happens. I wouldn't worry about a quake or two every few years, but this is every day and combined with the increased volcanism around the globe, this very well could be all related. This is just my hunch on things and you can take it with a grain of salt or ridicule me later if nothing happens, either way, take note and HEED!



Look at the below image. See the ridge there just north of the quake location...that valley below that ridge is the FAULT ZONE, and I don't mind yelling that over and over...I can feel every little shake, jiggle, and roll this damned thing does so it must be something. I live on that "wolf's head" ridge just SSE of Woolly Hollow, so we are moving at a different rate than what the seismographs at WHAR can read. WHAR is sitting on the "bank" of that ridge north of the fault and I sit south of it, then take into account the smaller micro-faults running through the plateau act like "tuning forks" and magnify every little move it makes. Just my two cents, since I sit here every day and almost get sea-sick, or feel like I am sliding.



With that said, I really wish someone can plop-down a portable seismograph up-here and take some readings; and in this case, the more the better and sooner better than later.

Don't everyone get all paranoid or freak-out about anything here I post; and the ideas presented are my own speculation based-on multiple hunches, which I feel are very possible alternative perspectives. Judge for yourself and please provide comments.

GODSPEED!

This map is hauntingly similar to many of the "Future" US maps I've seen various place. Thing is, that's what the rock under all the laminate layers of sediment cover up that we call solid ground looks like.

Take a look at this cross sectiom of what is typical of the Midwestern plains of the US. Layer upon layer of sediments of varying densities and properties. Throw in all the layers of water, and now the (minuscule amount when compared against groundwater, but still non-zero) frac fluid as well and we've got one large amount of unstable ground.

This image (that I've linked to a couple of times) shows a 3d rendering of the underlying rock of the Mississippi River Embayment. Look at that long rift and fairly deep valley. All of that is filled with those layers referenced above. Seismic waves would bounce around in that volume, echoing around that giant parabolic shaped rift valley.
Source

Maybe none of it matters and we're all wearing our hats a little too tight, but let's keep on shall we?

reply to post by jadedANDcynical


I agree, if there were many many more seismographs which could benefit from this parabolic shape to use as a natural receiver / amplifier, it would be a great benefit? Yes, let's keep-on. Maybe we can get some Stimulus Money or grant to form a working group to help bolster efforts of Universities around the state?

I would rather do that then wait and have to pick-up the pieces after a quake. Who knows, the oil drilling rigs are up here. We might could use a couple to relieve stress on some fault to PREVENT a major quake. Noble idea, but that takes millions of dollars, but it can be done if we put our mind to it.

reply to post by jadedANDcynical


Fascinating and that cross-section explains alot, especially when the ground-water level has been dropping in East Arkansas for decades little by little. As a kid, I would see sandy-ground in fields and places where you wouldn't think you'd find sand, but when Dr. Al-Shakri mentioned "sand blows" it rang like a bell. Shouldn't the farmers in the region in East Arkansas be asked to note them and inform the County Extension, Game / Fish, or some other Commission?

Who's up?

Certainly a little more active in the past day.
I know they have shut down two injection wells, but I can't stop wondering if they are fracking any new wells in that area. Or if recent fracking of a new well isn't causing some disturbance
Also, the Earth has been releasing some enourmous amounts of energy and the reverberations are being felt worldwide. Some truly amazing readjustments going on!

well I don't know about anyone else, but I was awakened within the last 30-45 minutes or so due to a couple of good little jolts. Well, actually, the dogs woke me up by climbing on top of me.. a couple of minutes later I felt the jolts.. No fun, no fun at all

reply to post by berkeleygal


Good Morning - I'm up now, but need to get ready for work :-( Looks like we had a few shakes the past few hours. I have noticed the Thursdays seem to be busy. Be safe Friends

Well, I see two big jolts on the seismo but nothing at all reported on USGS.

reply to post by berkeleygal


Had I been able to look at the time when they happened, I would've reported them to see if that made a difference.

reply to post by berkeleygal


I'm just learning on GEE, are the two jolts at about 12:16 & 12:19(ish)? just so i know if i'm looking at the right things I was refreshing USGS to see, but it's not been updated since 11:54

They are only listing one, but the webicorders are showing two.

The other one, at around 11:52:50 UTC, looks to me to be very near the same or maybe a fraction less. So, I expect they'll post it within an hour or so as a mag 2.5 to 2.6.

Hi bkaust, which station are you using on GEE at the moment? I don't see anything special at the times you mentioned (ie 12:16 or 12:19).
