5.0 Earthquake Hits Cushing, OK Nov 6

A magnitude earthquake hit Cushing, OK on Sunday night. Minor damage occurred in the downtown area. Two operators of the oil storage facility in Cushing reported no damage to storage facilities and pipelines from the earthquake. The numerous earthquakes in Oklahoma in recent years are tied to waste water injection in formations communicating with deep faults in the region, but not directly to hydraulic fracing of the oil-rich shales.
