The fracking drilling technique used to tap shale oil and gas is unlikely to trigger earthquakes, but underground  injection of waste water from drilling offers more risks for seismic activity, a new U.S. study said recently.

The National Research Council study, which also examined the risk of earthquakes associated with tapping geothermal energy and carbon capture and storage, found that the total balance of fluid injected or removed underground was the biggest factor in causing earthquakes related to energy development.

Although induced seismic events associated with these energy technologies have not resulted in loss of life or significant damage in the United States, some effects have been felt by local residents and have raised concern about additional seismic activity, the council said. The council’s report said fracking does not pose a highrisk for seismic events, citing only one 2.3 magnitude earthquake in Blackpool, England that has been officially linked to fracking for shale gas.
