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.

Interesting, I wonder why we haven't heard much, if anything on the news or in the paper about this.??

Early in the Fall, at least one of the Guy earthquakes did make the news here.

My guess is we're not hearing a lot about the "swarm" because 1. many of the earthquakes are small; 2. Guy is not a big town.

It is interesting to note that the mayor of Guy does not have earthquake insurance. Must be a *risk-taker* It might be cost prohibitive now to purchase.

We have earthquake insurance on our home here in Fayetteville. A cheap way (less than $200/year) to provide me some peace of mind.

A large majority of the earthquakes are somewhere at or below human perception. Only a small percentage of the swarm have actually been felt. There was one day a couple of months ago that 3 were felt within a 24 hour period, and it got a good bit of play on the L.R. TV stations.

Regardless, there is some concern that all the drilling for gas in that part of the state may be causing some of this. Anywhere you have drilling in shale, "fracking" (injecting fluids at high pressure) is involved to split open shale rock and release the gas trapped within. You've probably already heard the concerns that people have regarding those fluids possibly contaminating underground water sources. There is also the concern that the fluids may be lubricating friction points in fault lines, making it easier for the faults to slip, causing earthquakes.

I think I also remember reading somewhere speculation that the Guy swarm could be due to an extension of the New Madrid fault. Don't know much about that, though.

yep, I do remember something about it, but not to the extent of anyone letting it concern them too much.

Nita, remember the Baldwin Hills reservoirs disaster? That was caused by a fault underneath the dam being affected by fracking and overexploitation of the Inglewood oil patch.

I do, just vaguely..

Do they still practice "deep well waste" injections in Guy? If so, has anyone been monitoring exactly what has been injected?

Yes, and yes.

A 4.7 just about 1 hour ago again, near Guy, AR. I can't believe all these quakes in Arkansas lately. This catches my eye because I lived north of there in SW Missouri for many years.
