I think to remember that wet faults (as in "there is water mixed with the rocks") slide more frequently that dry faults and yield energy in less powerful bursts. If so, lubrificating faults could be a solution. Unfortunately I found a paper from 2017 [1] that suggests that it's not so simple. There are many more micro conditions that can trigger an earthquake.
