Oklahoma oil and gas regulators on Tuesday released details on new guidelines created to reduce earthquakes triggered by hydraulic fracturing in two of the state’s most-booming oil and gas fields.

Oklahoma’s oil and gas regulator for the first time will issue guidelines designed to reduce earthquake activity linked to hydraulic fracturing.

Attorneys are asking a district court judge to approve a class-action lawsuit against oil and gas companies after a 5.0-magnitude earthquake rattled near the town of Cushing in November.

Scientists may have a promising seismic forecast for Oklahoma over the next few years: A lot less shaky with a smaller chance for damaging earthquakes.

Newly published research bolsters a growing body of scientific findings linking the state’s earthquake boom and the underground injection of large amounts of wastewater from oil and gas production, but suggests the shaking could taper off after 2016.

The idea has been floated before but never really gained traction, The Journal Record‘s Sarah Terry-Cobo reports: “… An industry-funded entity that taxes oil and gas production, collecting fees for earthquake-related damages.”

The Pawnee Nation on Nov. 18 filed a lawsuit against two federal agencies. The suit mentions the 5.8-magnitude Labor Day weekend quake asks ”a judge to void recently approved drilling permits on tribal land and halt the issuance of new ones,” the World reports.

Attorneys are asking a judge in Pawnee County to approve a class-action lawsuit against oil and gas companies after the 5.8-magnitude earthquake that shook the area in September.

The action was brought on behalf of Pawnee resident James Adams. If a judge approves, other residents could join the lawsuit against oil and gas companies operating wastewater disposal wells in the area.

The magnitude-5.0 earthquake that struck near Cushing on Sunday caused one minor injury and damaged about 50 buildings. The shaking forced authorities to evacuate an assisted living center and left piles of rubble and broken glass on the streets.

Emergency crews worked through the night to secure buildings and survey destruction after the quake, which knocked out power and sheared brick facades off century-old buildings. 

A new study suggests some Los Angeles-area earthquakes in the 1920s and 1930s could have been caused by the oil boom at the time.

The paper, scheduled to be published online Tuesday in the Bulletin of the Seismological Society of America, presents evidence that drilling around Los Angeles between 1915 and 1932 could have been associated with damaging earthquakes in the area, including the magnitude 6.4 Long Beach quake in 1933 that killed 120 people.
