OKLAHOMA CITY (AP) — Members of a council that is studying an alarming increase in earthquakes in Oklahoma say it will take more time and research before officials understand how they are being triggered.
Oklahoma Gov. Mary Fallin and state Secretary of Energy and Environment Michael Teague met with members of the Coordinating Council on Seismic Activity Tuesday to discuss earthquake activity in the state.
The Oklahoma Geological Survey has said it's likely many earthquakes are being triggered by the injection of wastewater from oil and natural gas drilling operations.
The Oklahoma Corporation Commission, which regulates the oil and gas industry, has issued directives for well operators to change their depth and volume to prevent quakes.
But Teague says it could take up to a year before officials know if the directives have worked.
