Fracking doesn't cause earthquakes. Earthquakes are caused by tectonic plate shift.
Fracking may lubricate fault lines so that the energy stored by tectonic plate shifts is released more often, resulting in a larger number of small earthquakes.
The is a smaller number of big earthquakes: maybe one big one every 100 years or so. Which do you think people would prefer?
That’s a good and honest explanation for the layperson, like myself.
I suppose, if I knew the causative factors and probable results to expect, I could deal with a flurry of smaller quakes without going into full panic. That is similar to what I’ve been experiencing anyway in California.
