It’s not the fracking that is causing the quakes. It is the injection of water that is recovered after the fracking into disposal wells. They pick some deep sand layer below all of the aquifers and just pump it in.
It takes about one million gallons of water to frack a well.
1 million gallon of water to frac one well? I’ve been around many a well frac job and they sure as heck didn’t have 150 frac tanks sitting on the site. Maybe need to revisit your 1 million gallon statement.
Where the heck did you get THAT number for water????
How much water is used?
The amount of water necessary to successfully stimulate production in a gas well varies greatly. It primarily depends on the type of well drilled - horizontal or vertical - and the depth of the formation to be stimulated - shallow or deep. The deeper shale formations in the northeastern U.S. can use over four million gallons of water. Shallower, vertical wells typically will require much less water, about 100 thousand gallons or so, to complete the stimulation.

What about Water Usage?
It is not unusual for a typical deep shale gas well stimulation to require between 2 million and 4 million gallons of water. These numbers are significant, but they are small relative to the amount of water continually required to generate power from other energy sources.
