Well ... not really, but if you feel ok about it I'll allow it. You see, it all depends on which plates are doing what and at what depths and, well .... you're right about fracking not having any effect. I agree with you on that at least.

Fluid, if it creates enough pressure to create a fracture, is going to initiate the fracture in one way and one way only, perpendicular to the minimum horizontal stress. Which plates doing what and at what depths are going to have their faults to be enhanced by that fluid by any significant amount? If the fluid is creating a fracture, it's going to continue along the path of least resistance, dependent on the young's modulus, poisson's ratio, and overburden stress, but even then, the fluid will leak off instantaneously unless surface pressure is working against to replenish the void space.

I'm confused about what I know being wrong. I'm not a geologist, but I am a frac engineer and I have put a lot of fluid in a lot of formations at a lot of depths.
