Hawkmoon, I spent 32 years in oil and gas exploration. Specifically seismic data processing and acquisition.

Yes, there are areas where fracking can and does contribute to earthquakes. But, these quakes are not associated with faults and are far to shallow to be associated with the earths crust. Fracking occurs in the relatively shallow sediments that sit atop the crust.

The quakes that are associated with fracking are largely due to water injection that adds pressure to a hydrocarbon formation thus forcing the hydrocarbons to move to low pressure. An open pipe.

The quakes are relatively small, shallow and localized. Every area is geologically unique so quakes are only associated with a small subset of fracking areas.

All that said, if you happen to have a house right above a small frac induced quake, you could be screwed. House damage, septic system damage, etc...

I agree... when I said it was suggested early on, I wasn't dismissing it as completely bunk today, it does make sense since it does loosen the earth below, but maybe not all quakes, probably not the more significant ones...
