New research suggests that fracking is not a significant cause of earthquakes that can be felt on the surface.
UK scientists looked at quakes caused by human activity ranging from mining to oil drilling; only three could be attributed to hydraulic fracturing.
Most fracking events released the same amount of energy as jumping off a ladder, the Durham-based team said.
They argue that the integrity of well bores drilled for fracking is of much greater concern.
The research is published in the Journal of Marine and Petroleum Geology .
