Fracking is NOT causing most of the induced earthquakes. Wastewater disposal is the primary cause of the recent increase in earthquakes in the central United States.
Wastewater disposal wells typically operate for longer durations and inject much more fluid than hydraulic fracturing, making them more likely to induce earthquakes. Enhanced oil recovery injects fluid into rock layers where oil and gas have already been extracted, while wastewater injection often occurs in never-before-touched rocks. Therefore, wastewater injection can raise pressure levels more than enhanced oil recovery, and thus increases the likelihood of induced earthquakes.
Also it should be noted that earthquakes caused by fluid injection tend to be very mild. Most of them are not even noticed. Usually a few hundred a year are noticeable, but they tend be felt like a dump truck just drove by your house - you hear a rumble and maybe your windows tremble. And that is it.
