The severity and frequency of earthquakes in Colorado appears to be lessening, reports The Hutchinson News.

In the past three weeks, there has been just one quake of magnitude 2.0 or greater in the Sunflower State. Only one resident in the state felt that earthquake, which was centered underneath Anthony’s Forest Park Cemetery.

Oklahoma now has more earthquakes than any state in the lower 48, including California. And, as CNBC reports, the cause of all this shaking appears to be manmade. But can anything be done?


In early 1952 an Oklahoma City petroleum geologist named William Atkinson raised eyebrows by purchasing earthquake insurance for his home.

His odd decision looked like a bit of psychic brilliance a month later. In April of that year Oklahoma City experienced a powerful earthquake—the most powerful in the state’s history until last week.

Last week’s 5.6-magnitude earthquake in Oklahoma has now been upgraded to a 5.8, making it the highest magnitude earthquake in the state’s history.

In the wake of this massive quake, CNN Money has published an overview of what we know about these quakes.


Oklahoma fracking operations are facing a potential backlash in the wake of last week’s 5.6-magnitude earthquake, Bloomberg reports.

Last year, Oklahoma had almost 900 earthquakes of magnitude three or higher. Earlier this year Oklahoma regulators limited the disposal of oilfield wastewater in the state, hoping to prevent seismic activity. But this latest quake may trigger calls for more limits on wastewater wells in the state.

Some Oklahoma drivers have grown concerned about the structural integrity of the state’s bridges after last week’s 5.6 magnitude earthquake.

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.
