Hydraulic fracturing presents little risk of causing damaging earthquakes, a government study released today concludes, but earthquakes can be caused by other oil and gas activities, particularly injection of waste from drilling. Carbon capture and storage and geothermal energy projects can also lead to man-made earthquakes, says the report from the National Research Council. The report suggests implementing "best practices" for avoiding such earthquakes and having regulators make plans for when they begin to occur.
