Oops, the article does not fault fracking for the EQ activity. Wastewater disposal is known to facilitate seismic. It probably can be mitigated by lowering the injection rate.

Only the water disposal wells in the deep Arbuckle formation are being blamed. The Oklahoma Corporation Commission has taken steps to have those wells that are close to fault lines plugged back to shallower formations or injection rates reduced.
There has been a decrease in earthquake activity and strength since then. It will take time as there was quite a bit of water disposed in the Arbuckle and take a while for the effects to subside.
