Far Far back in time, there WERE active volcanos in Arkansas.
The diamond mine in Murfreesboro is an old volcanic kimberlite pipe and there are more places all around that area where lava reached the surface far far back in history extending at least southwest to Nashville where about 10 years ago there was also some commercial exploration for diamonds at a kimberlite pipe near the Nashville wastewater treatment plant.

The earthquakes near Guy and in Oklahoma are caused by natural gas frackturing injection wells and are not associated with New Madrid which is far to the northeast of Guy.
Those injection wells force water/chemicals very very deep and are very nearly exactly on top of the epicenter of the earthquakes.
Hydraulic fracturing [link to en.wikipedia.org]
Also the New Madrid seismic zone is separate, unrelated and pretty well defined.

The fracking water/chemicals lubricate the joints between rock formations and they slip a little.

If you read my post you would know that I was stating that there WERE volcanoes in Arkansas and when I plotted Earthquake locations in Arkansas it points directly to one of the most unique places in the world which is volcanically active, Hot springs, ar. As far as the cause of the quakes being Fracking, from the depth and rise in magnitude you can see that it is most likely not the cause. The quakes are occuring a good 3 miles below the maximum depth of the basin they are drilling in. The USGS does not even know what is going on there and have studied that area for almost 30 years, before hydraulic fracturing even existed. They even gave the area a name, The Enola swarm zone. I will post the E-mail I received from the USGS in a second stating that this has been going on longer than that technology existed.

So it is just total coincidence that the earthquakes are happening right where the injection wells are?
The injection wells force water/chemicals into every nook and crannie far below and to the sides of the well depth.

USGS states: "A M3.8 earthquake is not unprecedented in central Arkansas. Northern Faulkner County and parts of adjoining counties have had small earthquakes at least since the start of 1982. That year saw a swarm of more than 17,000 shocks, nearly all of which were too small to feel. The 1982 swarm was named after the nearby town of Enola. Earthquake activity decreased through 1982 and remained low after that. It picked up again in 2009, although not to the level of 1982. Earthquakes of magnitude 4.0 or larger occurred in the swarm area on January 21, 1982 (M 4.3); May 4, 2001 (M 4.3); and October 11, 2010 (M 4.0)."

AGS hazards supervisor states: "“If you think about it, there’s over 2,000 production wells in the shale area; if there’s a relationship between the two, these earthquakes should be all over where the wells are, but this isn’t the case,” Ausbrooks added."

That's not what the guy on the news said. Also I read an article that stated back in Sept. Fracking was suspended in that area...
