Skip to comments.Earthquake 'swarm' rattles Arkansas town and its residents
Posted on 12/14/2010 9:56:01 AM PST by FromLori
The Arkansas Geological Survey is trying to unravel a mystery: What is causing earthquakes in the town of Guy, Arkansas?
Since September 20, the community of 549 residents north of Little Rock has experienced an almost constant shaking from 487 measurable earthquakes.
"We've had 15 today including a 3.1 (magnitude) from this morning," Scott Ausbrooks, geohazards supervisor for the Geological Survey, said Monday. "These are shallow quakes between two and eight kilometers (between one-and-a-quarter and five miles) below the surface."
While earthquakes aren't unusual in the Southeast state, the frequency is.
"This time last year we had 39 quakes total for the entire state," said Ausbrooks.
Most of the quakes in the swarm -- a localized surge of earthquakes with all of them about the same magnitude, according to the United States Geological Survey -- are so small they go unnoticed. The largest, a 4.0 on October 11, caused the only documented damage, cracking a window at a visitor's center to a state park.

New Madrid getting itchy? Yikes.
Also, we're seeing an average of 5+ earthquakes daily worldwide. If this keeps up, we'll see over a 50% increase from previous historical average for the last 40 years.
Global Earthquackery! We're all gonna die!!! :)
Tektonic plates, the great recycler of the world. It just takes a while on our watch.
Obviously, this is further proof of global warming.
Are we about to see the equivalent of the Christmas quake in Indonesia?
You got company!
What's safety in a tornado can be death in an earthquakes
call kevin bacon,,,its tremors....lol...
Scouts Out! Cavalry Ho!
I hope it doesn’t let lose at 3 am
That and stay away from the Santa Monica Freeway
Are we sure Hillary’s not back in Arkansas for a visit? :P
New Madrid is 200 miles away. It doesn’t mean that there is not a connection with these and the quakes in Oklahoma.
Do you think Kevin Bacon’s wife is hot ?
If you see squirrels swimming across the Mississippi or the Ohio, get out of town quick!
If a guy named Tecumseh has a brother-in-law that talks alot about it, also get away fast!
Should be some good ones next week as the total lunar eclipse is less than a day away from the solstice. Good push/pull gravity from the moon and sun.
The New Madrid fault line extends down into Arkansas. I believe Guy is about 100 miles from the fault line.
Could be related to Ok. Could be anything really.
Researchers, however, are quick to point out that there is a history of earthquake swarms in Arkansas that predate the widespread gas-drilling. In 1982-83, and again in 2001, swarms were centered near Enola, less than 10 miles southeast of Guy.
But don't tell the anti-fracking crowd, I'm sure they will be using this as yet more 'proof' of the evils of fracking wells.
My parents don’t live too far away, and this is what they’re hearing.....
It’s just some construction work on the Underground City designed to house the Ruling Elite should the ‘worst’ happen.
Man-made Global Warming?
It’s them HOGS stampeding for the Sugar Bowl!
Good luck with the Mayor trying to buy Earth Quake insurance. No company worth their while will insure anyone in that town.
See post 25.

Obviously Bush’s fault! (pun intended)
These seem to be a bit centered about where there has been a bit of activity historically, perhaps a bit north of it.
There are far bigger reasons to be wary of fracking...it really seems that this is a red herring, though I am not offering that as a professional opinion. :-)
See the dots to the east...they are New Madrid events. The star is the most recent event (Dec 7).
Note how the Seismic Hazard Map shows the New Madrid to the east, and this is pretty far off it.
Note, however, I am not a seismologist.
Could be somebody's been a runnin' off a damn good batch
lol the ruling elite is delusional if they think that will save them when SHTF.
Elite’s Pathological Dysfunction?
Nice maps. If I had the time and I wasn’t so lazy I would look for some GIS data and play more with this. But I have been spending a lot of time shoveling snow this week!
Darn that global warming! ;)
There’s a 2003 USGS pub with the GIS data of historical seismicity of the central US (Mississippi valley, basically), IIRC, but I can’t recall the authors. I’ll let you know if I find it.
Of course, the old data in it is sketchy.
Actually they have the most current data here (assuming my 30 second look at the site is correct!):
And, you can download a file of well locations here (Excel format):
I usually use the crippled version of GlobalMapper that the USGS gives away free here:
It will import comma separated value files which you can make from the Excel file of wells and the txt files of earthquakes. Assuming you can tell what the projections are for each data set, it may even provide a useful map! I may play with it tomorrow.
Now I am going to go look for DRG topo files for Arkansas.
Yep, that was my first thought. I hope we’re wrong.
I have said several times that I think we will have one more world class earthquake or volcano before the earth settles down for another quieter period of around 70 years. It seems at least in the past few centuries that every 100 years there is a period of about 30 years when there are more and greater earthquakes and volcanos. I think this cycle is not quite over.
Brick homes are a common thing in the Arkansas/Oklahoma area.

Then I took the screen dump of recent earthquakes around Guy from the AGS site and plotted the nearby injection well locations:
What about pre-recent earthquakes?
Correlation based on geology of predisposition of both gas content and tectonic activity?
I think it’s the timing that’s the key...did the earthquakes pre-date the drilling?
With that kind of logic you will never be allowed into the Green Church. ;>) They do have a list of all historical earthquakes, but I am not sure it includes the smaller ones. I will take a look at it today. It would be fun to make an animated Gif of a time lapse of earthquakes in the area.
One thing I find interesting about the maps I posted is the scale of the area with recent activity versus the location of injection wells. I find it hard to believe that those two wells could have been responsible for such a large region of seismic activity.
