The earthquakes in OK aren’t a direct result of fracing. With a few rare exceptions, oil & gas fracs are accomplished through hydraulic force rather than thermal effects. The induced seismicity in OK is a product of water disposal wells which can raise pore pressure causing faults to slip. The microseismic events that occur during the actual fracing process can only be measured with highly sensitive geophones.
