Scientists, regulators and technical experts from the energy industry met in Oklahoma to discuss how earthquakes triggered by oil and gas operations should be accounted for on national seismic hazard maps, which are used by the construction and insurance industries and pubic safety planners.

The three-day workshop started Nov. 17 and was co-hosted by the Oklahoma Geological Survey and the U.S. Geological Survey.

Oklahoma’s earthquake surge is unrelenting. The shaking is rattling residents and cracking the foundations of homes.

The quakes have also strained state agencies, which are struggling to keep up with the ongoing swarm while simultaneously developing a longer-term plan to analyze and address factors that might be triggering the earthquakes.

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.

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.

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.
