Earthquakes of magnitude 4.0, 4.3, and 4.5 have hit the oil and gas hub of Cushing, Oklahoma, over the past 2 years. By considering the two smaller earthquakes, McNamara et al. suggest that a much larger earthquake could occur directly below the Cushing oil facility. Earthquakes can redistribute stress, and in this case it appears that this has occurred on the Wilzetta-Whitetail fault just south of Cushing. The most recent, larger earthquake adds to the concern that a more damaging quake is in the region's future.
