Oklahoma’s earthquake surge and possible links to oil and gas activity have been studied in scientific papers, discussed at heated town-hall meetings and explored regulatory hearings.

The quakes are now triggering some rumblings at the state Capitol.

About 4,000 earthquakes have shaken Oklahoma this year, data from the Oklahoma Geological Survey show. Most of the quakes have been small — roughly 10 percent were 3.0-magnitude or greater, the threshold at which seismologists say the temblors are likely perceivable.

Watch Al Jazeera’s Video On Oklahoma Drilling And ‘Far From Normal’ Earthquakes

Al Jazeera Plus produced a 10-minute video on Oklahoma’s earthquake swarm, which included interviews with worried residents and activists and explored some of the science that has linked the seismic surge to wastewater disposal wells used by the oil and gas industry.

The 5.7-magnitude earthquake that struck near Prague, Okla., in November 2011 toppled Sandra Ladra’s chimney, raining rocks “on her lap and legs.”

Ladra on Aug. 4 filed a lawsuit against energy companies that operate disposal wells she claims caused the quake. She is seeking $75,000 in actual damages plus punitive damages, the Journal Record‘s D. Ray Tuttle reports.

The U.S. Geological Survey says at least four earthquakes have rattled central Oklahoma, including a 4.3-magnitude temblor near Langston.

The earthquake struck shortly after noon Saturday about five miles southwest of Langston. Earlier, a 3.2-magnitude quake was recorded about 6:30 a.m. in about the same area near Langston. No damage or injuries were reported following either quake.

Town Hall Turns Testy As Oklahomans Seek Action And Answers On Earthquakes

Shaken residents line up inside Edmond's Waterloo Road Baptist Church to voice concerns and ask representatives from the Corporation Commission and the state Geological Survey questions about recent earthquakes.

Oklahomans rattled by a surge of earthquakes on Thursday packed a contentious town hall meeting in Edmond and demanded answers and action from public officials.

There was booing and shouts for regulators to impose a moratorium on wastewater disposal wells used by the oil and gas industry, which scientists have linked to Oklahoma’s exponential increase in earthquake activity.

To Get Permit In Earthquake Zone, Disposal Well Operator Agrees To Extra Monitoring

An oil company seeking to build a disposal well in earthquake-prone Logan County has agreed to record additional pressure and volume measurements to get a permit from the state’s oil and gas regulator.

The Oklahoma Corporation Commission on Thursday voted 2-0 to approve the disposal well for Kansas-based Slawson Exploration. Commissioner Dana Murphy abstained from the vote “saying she wanted to wait until more seismic data was available,” The Oklahoman‘s Paul Monies reports:

Red Tape, Not Rules, Used To Manage Disposal Wells In Oklahoma's Earthquake Country

Joe Wertz StateImpact Oklahoma

As earthquakes continue to shake the state and researchers study links to drilling, Oklahoma’s oil and gas regulator has changed the way it approves permits for injection wells.

Oil and water have long mixed in Oklahoma and other petroleum states. In the early days of the U.S. oil boom, drillers were focused on finding ways to separate water from the oil they were pumping to the surface.

Very few Oklahomans carry earthquake insurance, less than 1 percent. But that’s beginning to change as the state experiences more and more temblors.

Oklahoma’s Earthquake ‘Swarm’ In One Chart

EQ Charts has created a really great visual of Oklahoma’s earthquake “swarm.” The chart was built with data from the U.S. Geological Survey, and shows quakes of 2.0-magnitude or greater. Most people can feel earthquakes that are 3.0-magnitude or greater.

Earthquakes have increased exponentially in Oklahoma, a phenomenon federal and university seismologists have linked to disposal wells used by the oil and gas industry.

Earthquakes No Danger To Cushing Oil Hub, Energy Officials Say

The Cushing oil hub is crowded with hulking oil tanks, miles of pipeline and countless pumps, compressors and other equipment used to ferry around the roughly 80 million barrels of crude stored there.

Oklahoma has experienced a swarm of earthquakes, which seismologists say might be triggered by disposal wells used by the oil and gas industry, and it’s not hard to imagine the havoc a little earth-shaking might have on the high-profile oil hub.
