The number of Oklahoma earthquakes registering a magnitude 3.0 or greater has declined for the third consecutive year after state regulators began directing oil and natural gas producers to close some wells and reduce injection volumes in others. The number …
Scientists may have found previously unmapped faults in Oklahoma that could be contributing to a sharp increase in induced earthquakes in the state, according to a report on a study that used magnetic imaging to explore the rock formations below …
Experts are looking at how Oklahoma’s seismic activity impacts critical infrastructure as frequent, low-level earthquake swarms continue to pop off throughout the state. The Tulsa World reports that Oklahoma has experienced 80 earthquakes of 3.0 or greater magnitudes this year …
The Oklahoma Geological Survey has proposed to install more than 70 permanent seismic stations across the state that would allow scientists to better study earthquakes. The $3.5 million proposal would be placed in a grid pattern and phased in for …
The Oklahoma Corporation Commission says its Induced Seismicity Department and the Oklahoma Geological Survey are investigating several earthquakes in the central part of the state. At least six quakes of magnitude 3.0 or stronger have struck since Tuesday in an …
A white Chevy Suburban with “Railroad Commission of Texas” emblazoned on its side rolled north on Interstate 35. Behind the wheel sat Milton Rister, the commission’s director. Trim and balding, Rister was a veteran political operator who had held influential …
A 5.0 magnitude earthquake struck Oklahoma on the evening of Nov. 6 near the town of Cushing, an area that has experienced increased seismic activity since 2015, the Oklahoma Geological Survey reported. Several aftershocks, the largest of which was magnitude …
A 5.8-magnitude earthquake and a series of smaller aftershocks in Oklahoma led to the discovery of a new fault line and stoked fears among some scientists about activity along other unknown faults that could be triggered by oil and gas …
Damage estimates of insured losses from the earthquake that hit Pawnee, Okla., in the north central part of the state on Sept. 3 likely won’t be available until early October, according to an insurance department spokesperson. In an email, Assistant …
The Oklahoma Geological Survey is studying the relationship between seismic activity and wastewater injection wells with a survey in the Arbuckle formation. Sensors will be placed into several injection wells in the Arbuckle group to take various measurements. The Enid …
