Oklahoma has announced a new plan to slow the staggering rise of earthquakes in the state, reports The Rural Blog. The earthquakes have been linked to fracking and wastewater disposal performed by the oil and gas industry. The new plan will cover more than 5,200 square miles of central Oklahoma.

The Sierra Club has filed a federal lawsuit against three Oklahoma energy companies, reports StateImpact Oklahoma. The lawsuit accuses the companies of operating wastewater injection wells that contributed to the massive spike in earthquakes in the state. The three oil companies facing the accusations are Chesapeake Energy, Devon Energy and New Dominion.

Oklahoma state officials set out a couple of years ago to find which buildings in the state were most vulnerable to earthquakes. Today, lawmakers are no closer to knowing which structures would be most likely to collapse, reports NewsOK. That’s because the team of experts the state hired never performed the work requested of them. The team balked out of fears they might be held liable should their predictions prove wrong.

Elvis wasn’t the only the person to note a whole lotta shakin’ goin’ on. Lately, it appears that even more of it is taking place. Kansas residents have experienced plenty of recent unexpected movement as the earth repeatedly shifts under feet and houses. This messes with people’s equilibria and generates questions.

Last week’s cluster of earthquakes in Edmond, Oklahoma, have revealed a previously unknown fault line, according to NewsOK. This new information could mean more earthquakes in the future, says seismologist Daniel McNamara. Researchers have been using oil and gas industry data to identify previously undocumented fault lines in the state. But sometimes faults are revealed when a series of earthquakes fire off with epicenters in a linear pattern. This is what happened last week in Edmond.

Oklahoma had more earthquakes in 2015 than every continental state combined, reports Oklahoma City station KOCO. 49 U.S. states—excluding the massive Alaska—recorded a total of almost 1,600 earthquakes of magnitude 3 or greater last year. Of those, almost 900 were in Oklahoma. The other states had a combined total of 729.

Scientists say oil and gas activity is probably responsible for the surge in earthquake activity in Oklahoma.  They call the phenomenon “induced seismicity.”  But, researchers are puzzled.  Oil and gas production is nothing new in the Sooner State, and why is there an increase in quakes in Oklahoma, or for that matter Texas, Colorado, and Kansas when it doesn’t seem to be happening in other major players like North Dakota?

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.

Although the cause is under debate, the fact is Oklahoma ranks second in seismic activity in the continental United States according to analysis done by EnergyWire.
