State regulators need to pay more attention to human activities, such as oil and natural gas development, that have the potential to cause earthquakes, according to a 150-page report released Monday by the StatesFirst Initiative.

Pennsylvania regulators said Tuesday that they would step up efforts to monitor for both naturally occurring and human-induced earthquakes throughout the state in a partnership that’s expected to improve the safety of oil and gas permitting decisions and geologic mapping.

Oil and natural gas operators need to cut back on waste fluids that are injected into wells to help reduce the outbreak of small earthquakes, which are occurring with increasing frequency in the Midcontinent, according to two recent studies.

A division of the Ohio Department of Natural Resources (ODNR) will be receiving four new seismometers and plans to deploy at least two of them in the western and northwestern parts of the state, enabling it to monitor more of the state for seismic activity.

A study linking seismic activity with oil/natural gas drilling activities got the attention of the newest commissioner on the Railroad Commission of Texas (RRC) on Thursday, and then his two colleagues jumped on the injection well-seismicity bandwagon Friday.

New research published by the Bulletin of the Seismological Society of America reaffirms conclusions reached by Ohio regulators that horizontal hydraulic fracturing operations at a Hilcorp Energy Co. site in March activated a previously unknown fault line and triggered a series of earthquakes.
