probability curves for seismic hazards

Caption

The model shows earthquake probability curves for central Oklahoma increasing to 2015 due to brine injection. After injection is reduced and assumed to end in 2017, brine continues to diffuse in the rock, and the curves retreat to background levels. The new model allows operators to compute quake probability for various injection scenarios, maximizing injection while minimizing hazards.
