Fracking Earthquakes

Fracturing the rock causes seismic activity which can be felt on the surface and can even damage properties, is this true?

A:

Not entirely. Fracking "can" cause seismic activity but only very rarely. You'll hear them referred to as earthquakes but they are really just earth tremors. There is no evidence that the magnitude 1.1 and 2.3  tremors in 2011 were felt by anyone at the surface, just anecdotal references. There is a low to negligible chance of surface damage ever occurring according to experts - you can read more about fracking and earthquakes here.
