Arkansas has had 500 quakes since 9/20. Gas drilling to blame?

[PhillySane]

Disposal wells (drill waste being pumped back into the earth) are being looked at as a possible cause.

1. I liked this part:

The state also will soon become one of a few to require companies to disclose the chemicals used in fracking fluid, the water-and-chemical solution used in high-pressure drilling operations

2. Right

Drill first, ask questions later. Like, "Could this be harmful to us all??"

3. The quakes are all in a very tight configuration and they're all

shallow and nearly the same depth. Either it's the chemicals and physical disruption of the bedrock or they've awakened a Balroc.
