Drill here, drill NOW!

Did you feel the earthquake last night?

I didn't, but Derek did. He hit me on messenger shortly after it happened asking if I'd felt it. I said no, and then proceeded to look online to see if there was any updated information.

Here's what I found. (PDF)

Though no definite conclusions were reached, the USGS clearly believes that fracking is responsible. With the addition of several, even more powerful earthquakes in the same area in recent days, it is clear to me that hydraulic fracking in the area is what caused them.

The quake last night was a 5.6, the largest ever recorded in Oklahoma.
