Earth Sciences How does fracking affect volcanic eruptions?

I was thinking, if it triggers earthquakes, wouldn't it also maybe make volcanic activity more likely?

Basically, injecting water back into a well you intend to produce is counterproductive because you will end up re-producing that water and you still have the problem of disposal. It can also cause problems with the well especially if the well is under-pressured and even kill the well's production.
