Glad to assist. If you have any difficulties then just let us know and I'm sure someone on here will be able to help.

Watching instructional videos from Windows never helps!

But seriously, I'm glad you got it sorted. The more who can post images, the better.

Back fully on topic (ie fracking and the damage it causes, at least), does anyone recall if the following article has been posted already? I don't recall seeing it. It's from Vanity Fair (no less!) and is entitled "A Colossal Fracking Mess -- The dirty truth behind the new natural gas". This report is about gas drilling and fracking in Pennsylvania, but the horrors it relates would certainly be relevant to what's going on in Arkansas. The report is utterly scathing of the processes used to extract the gas and well worth a read.

I know you are saying to ignore those two bands, but I have noticed everytime I start getting the swaying feeling again and they headaches start pounding and the nausea hits, those funny looking waves are all over the place on the graph, It might be a small quake but it seems to coincide with events right here where I am located at that time, does that make any sense to any of you.


Why am I feeling all of these small quakes that I should be able to ignore?

reply to post by SusanFrey

Nothing of any significance showed up on the seismos, so as your house is swaying it's very hard to say what's going on. I'm only speculating here (with no degree to back me up, please note), but it makes me think that the ground movement has to be very local to you and perhaps of a form that is not affecting the closest seismos.

OK let me add this to that thought. You know when you go over a hill or bump in a car and your stomach sinks in as you go down. I am getting those sensations as well with these lines.

Having followed this thread from the start, my thoughts are with you guys in the 'firing line' .. so to speak.
Susan, not sure if you can .. or you would want to, but you could record via camcorder or phone what you are experiencing and upload to Youtube. Place it on the floor and I am sure it would pick up any movement or rumble. Might give us some insight as to what you have to put up with on a daily (and hourly) basis.

That might be a good idea. I will try to figure out a way to do that, my chair is bouncing here up and down ever so slightly as I type,

BHE/BHN are lateral channels and that totally makes sense. They record motion from side to side, in either a east-west or north-south direction. The problem is a lot of things can cause that, and especially on a TA station, which are all mounted above ground and prone to wind noise, animals, etc. You can monitor them if you like- it's just that beware, they will often display stuff that will fool you. And that's why personally I recommend you don't watch them until you become much more experienced in identifying wave signatures in GEE. Best to start with verticals only for a while, I promise.

EDIT TO ADD: TrueAmerican, I posted this before reading your above post. Okay, that kinda answers my question. So maybe the most important thing right is correlation between what is seen and what is felt.

Here is a great video link posted by AorAki over on the quake thread. It is done by someone over in NZ, showing how the ground liquifaction occurs. VIDEO

Edit to add:

Watch the above video on liquifaction.....very enlightening

TrueAmerican, I hear what you are saying and I could very well be wrong. What I am looking at though, is a correlation between this wide, wavey patterns shown here:





Matching up with reports by susan of increased rumbling, ground motion, etc. I understand that these are not a vertical channel. Does that mean they should be dismissed though? Do you have an idea as to what they are recording? You obviously understand reading these stations better than I do and I have a great respect for your knowledge so maybe you can figure out what it is? Is it possible (laugh at me for this if you want), that this is showing horizontal movement? If the liquifaction is coming into play here, than would there not be an increase in the peak velocity that is occuring but also a change in the readings on the seismos and how the motion is felt?

Have you tried eating corn? You are most likely now become hyper-sensitive. You are suffering from stress. You know I have supported everything you've done. I think watching every wave, and feeling every wave is too much for you. I want to ask you to go do a hobby for awhile. Take your mind of this as much you can. You've alread though through what you would do if there was an emergency and planned for it. Reassure yourself that you've done all you can on that front.

Back in World War I and WWII, they would call it shell shock. Let's face it. There's not much difference. When the artillery shells hit the ground they would produce and earthquake. You've been a good soldier. But even soldiers need rest.

I don't want to say much about the quakes at this moment. But that last cluster wasn't that energetic. So, look at the positive. You had a good night last night, and the bumps today haven't been as big. Go do something for yourself. Be selfish. Enjoy a vice. Whatever. Just please. Take care of yourself first.

You'll be a better soldier after you unwind a bit.

You're relieved of your duties.
Salute.

Susan, would you like to try something as a little experiment?

Do you have a spirit level around the place? If so, use it to find a surface that's dead level. A benchtop or the top of a coffee table or something like that. Get a marble or a ball bearing or something perfectly spherical and place it on the flat surface and cover it with a clear bowl (plastic or glass) so nothing can touch it and so that the marble is in the middle under the bowl. (A large glass will do if you don't have a suitable bowl.)

The next time you notice these lurches, see if the marble moves at all. If it does, then you can work out the relative horizontal direction of the movement. Because from what you've been saying I'm thinking you're getting more horizontal movement than vertical.

Also, if you have a pen and paper handy to note the exact time that will be helpful.

Oh, if you don't have a spirit level then just try a marble on what looks like a flat surface and find where it's actually level and leave it there, then put the bowl over it.

EDIT to add: and yes I agree about eating some corn. If you have none around (even popcorn will do) then have some oatmeal as it's also a good source of melatonin.

I also agree that you've probably become more sensitive than most because you've been focused on this so much. I can imagine I'd be the same, to be honest.

Well, it's showing peak ground acceleration. That's why the display is nanometers/sec or microns/sec. But just keep in mind how small a micron is much less a nanometer (1000th of a micron). We are talking insanely small ground movement here, and typical for your everyday seismometer, anywhere, any place. Even so, no it should not be disregarded. I also remind you, you are talking about stations that are some 50 to 80 miles away from where these quakes are occurring. That is crucial to your understanding of what you are seeing in GEE on W40A and X40A, especially on the BHE/BHN channels. In fact they are far enough away that any ground acceleration on such a small scale is likely local to the station, and not 80 miles away.

Okay, thank you so much for the clarification. That helps with understanding what we are seeing/not seeing.

OK I have things set up and this does give me something to do and Robin I'm OK. I have a small glass of water with blue food coloring in it. A blue marble under a clear tupperware container and a small level sitting on the carpeted floor on a board that is level with a level on the board as well. I even put the fingernail clipper on the board. LOL!!! Now this I enjoy and it gives me something to show you. Now to setup the camera and lights and I can start recording things.

I can see you teaching small children this in school

I'm new to ATS and have been reading this topic for hours. I'm in NWA and I feel them, not always under my feet so to speak but if sleeping I wake up, I have began to write time the time I wake then check on Ceri the next morning to see if it shows anything. A few minutes prior to the ones that are over 4 I feel sudden nausea and feel like I'm going to faint. During regular waking hours I just feel anxious. This has been going on since they started and no I don't really talk to anyone about them other than my sister because I don't need to be told what a nut I am. It is a hard think to turn off not thinking about it and I don't want to be a doom and gloom person. I'm starting to do some productive things..getting rid of extra junk, making quilts and spinning yarn. The spinning sure seems to help.

Okay, so in talking with Susan regarding her location and looking at the maps, taking into consideration that the peak velocity seems to be migrating to the south I have tried to locate the best stations on GEE to look at. It would make sense then for the stations that are showing the most horizontal 'movement' (if that's what it is), would be the ones to the south. Keep in mind that while these stations are about 50 miles from where Susan is....she is feeling a lot more than is being 'recorded'. We don't know where the true epicenter of what she is experiencing is coming from. Who knows what one of these would look like if it were located closer to her?

Anyways, those stations on GEE are:

TA.X40A and
US.MIAR

They are BOTH showing quite pronounced, drawn out waves, like the screen shot that I posted above.

Station TA.U40A, which is the closest one to the NORTH, is also showing some of this, but not as pronounced.

I think that we should watch these stations and see if there is any correlation to what Susan is reporting (and recording)





ETA: Another thing to note. Susan just felt the last very small quake. It showed up on GEE, and on IRIS as a very mirco jolt. Interestingly, it shows the greatest on the two stations that are also showing the waves...I think this goes a ways in confirming that these stations are, in fact, closest to whatever is currently going on and Susan is feeling.

ur44lois you may want to check out page 140, scroll down to the references posted, plenty to read up on there, too. Welcome along.

I'm trying different things here to see which you can see thing better with.
It may take me a while but I"m working on it.

I should have known you'd disobey orders and stay on duty. You're a REAL trooper.

Looking forward to your experiment Susan.

Can't believe only one quake registered today and its been going on for hours.
