Sandra Ladra, a resident of Prague, Oklahoma, was injured during a 2011 earthquake. Mounting evidence has shown that the earthquakes were caused by the injection of wastewater from fracking. So Sandra decided to sue the oil and gas companies that operate injection wells in her area.

The Wall Street Journal has published a debate about whether oil companies should be held liable for injuries caused by the quakes.

The largest commercial oil storage hub in North America is located in Cushing, Oklahoma, reports Bloomberg Business. In the wake of 9/11, concerns were raised about Cushing’s status as a potential target for terrorist attacks. The Safety Alliance of Cushing was formed as a result: an alliance of the FBI, state and local law enforcement and emergency officials.

After Oklahoma issued regulatory actions to try to curb a rash of oil-industry-related earthquakes in the state, one oil and gas operator is challenging the ruling, reports StateImpact Oklahoma. The Marjo Operating Co. Inc.’s filing is the first effort on the part of the oil and gas industry to prevent regulation.

In light of recent earthquakes, officials near the oil hub in Cushing, Oklahoma, are considering a worst-case scenario plan. According to the Journal Record, 11 magnitude 3.0 or greater earthquakes have been recorded near the Cushing oil hub since April. If one tank were damaged in a quake, oil companies could easily respond. But if all of the storage tanks were damaged by large earthquakes, first responders would be overwhelmed.

last month Oklahoma Governor Mary Fallin finally acknowledged the oil industry’s culpability in the state’s recent spate of earthquakes. Meanwhile, on August 3rd the state imposed strict new limits on how much waste fluid companies can pump. These cuts are the state’s latest effort to stop the earthquakes, reports NPR member station KOSU. The new regulations require the amount of waste fluid to be cut by 38 percent by October.

The Oklahoma state seismologist said disposal wells used by the oil and gas industry are ‘very likely’ responsible for the recent surge of earthquakes in Oklahoma at the recent Oklahoma Geological Survey.  This report is from State Impact Oklahoma.

Austin Holland says the rates and trends in seismicity are very unlikely to represent a naturally occurring process in a joint statement with agency interim director Richard D Andrews.

The agency’s acknowledgement follows years of peer-reviewed research linking disposal wells and earthquakes.

Despite long-held suspicions that Oklahoma’s earthquake surge was linked to oil and gas activity, the Oklahoma Geological Survey stay silent amid pressure from oil company executives. State Seismologist Austin Holland admits “intense personal interest” from energy company executives, but says it never affected his scientific findings.

Scientists, regulators and technical experts from the energy industry met in Oklahoma recently.  They discussed how earthquakes triggered by oil and gas operations should be accounted for on national seismic hazard maps reports StateImpact Oklahoma.


Texas regulators recently tightened up the rules for disposal wells- the ones that get rid of oilfield waste.  The action was in response to a cluster of earthquakes that have rattled North Texas according to a recent article from StateImpact Texas

Kansas Chamber snubs seven Republicans in state House endorsements

An oil industry geologist wants to shift the finger pointing away from the oil industry as the cause of the earthquakes in Oklahoma.  At a recent conference sponsored by the Oklahoma City Geological Society, Glen Brown, vice president of geology at Continental Resources, Inc. says the “tectonic plates are more likely to blame for the tremors in Oklahoma,” according to a recent article from the Journal Record.

The Railroad Commission of Texas recently met.  Commissioner David Porter announced the search for a staff seismologist in response to the rash of small earthquakes that have sprung up throughout the state along with the boom in oil and gas production reported Mose Buchele for StateImpact Texas.

 A new study from the University of Texas shows the recent cluster of earthquakes are mostly caused by oil and gas extraction reported State Impact Texas

Cliff Frohlich is the Associate Director at UT’s Institute for Geophysics and lead author of the study. 

“The question we were looking at was, were quakes in the area linked to the disposal of hydrofracking waste?” said Frohlich.
