I do a daily OK earthquake report as one of my many job duties. These quakes are caused by critically stress faults (faults that are bound to break 'sometime') lubricated by wastewater disposal, not fracing. Although fracing can cause minor quakes <M2.5, it is the wastewater produced from the watery Mississippi Lime formation in the NW part of the state when reinjected into deeper formations that causes the major quakes. Once the water migrates to a critically stressed fault (N35E direction) and lubricates it enough to release the stored energy, the fault breaks causing the earthquake. The OGS has been issuing advisories to these waste water well operators and have set demands of cutting back rates, and in some cases, shutting the well in. So many people are misinformed about the fracing process and immediately put the cause of these quakes as solely being fracing induced seismic events.
