Are Arkansas Earthquakes Related to Fracking?

Excerpt:

Arkansas has been hit with a ton of earthquakes lately (as well as mass fish and bird deaths), and a large number of the earthquakes haven’t even been in the New Madrid Fault region. A number of people have been drawing a connection between the earthquakes and hydraulic fracturing (aka fracking), and two gas disposal sites have actually been suspended from use of injection wells (the prime suspect) now.

“The Arkansas Oil and Gas commission says there is likely a link between the wells and the earthquakes,” Sarah Eddington of The Seattle Times writes. “There have been more than 800 quakes in the area in the past six months. with a magnitude 4.7 quake, the strongest in Arkansas in 35 years, hit there Sunday.”

Fracking caused the quakes and AGW caused the fish and bird deaths.

A 4.7 in OK last evening:

"No damage or injuries were reported. Oklahomans have been warned that aftershocks following Saturday's 5.6 magnitude quake could continue for weeks or months."

Experts advise the relatively large tremors are not the result of human activities:

"Earlier this year, Holland wrote a report about a different flurry of Oklahoma quakes last January -- the strongest a 2.8 magnitude -- that seemed to occur with hydraulic fracturing. [Oklahoma Geological Survey seismologist Austin] Holland said it was a 50-50 chance that the gas drilling technique caused the tremors.

That is the largest tremor associated with fracking in the scientific literature, experts say. And the strongest of this weekend's natural quakes, magnitude-5.6, released nearly 16,000 times the energy of the worst from that January flurry."

Experts? Ha! Fracking could have set off a chain reaction of seismic events. Nobody knows for sure, regardless of how much they're being paid to act as if they do.
