Is it possible to anticipate whether a planned wastewater disposal activity will trigger earthquakes that are large enough to be of concern?

Currently, there are no methods available to do this. Three conditions must be met for injection to induce an earthquake:  1) presence of a fault; 2) stresses acting on the fault favorable to slip and 3) a pathway for the pressure increase from injection to interact with the fault.  Evidence from some case histories suggests that the magnitude of the largest earthquake tends to increase as the total volume of injected wastewater increases. The rate of injection may also be a factor. More research is needed to determine the answer to this important question.
