Good news! Fracking doesn’t cause earthquakes. Or, to be more precise, hydraulic fracturing for gas is not a significant cause of felt seismic activity. Or, to be even more precise, it does cause earthquakes, but it’s not one of the biggest man-made causes of large (that is, noticeable at the surface) earthquakes. A new study shows that fracking can reactivate dormant faults, but if frackers use 3D seismic imaging, then according to Richard Davies, director of the Durham Energy Institute and study leader, they ‘can avoid faults that are critically stressed and already near breaking point”.
