It’s Official: Injection of Fracking Wastewater Caused Kansas’ Biggest Earthquake

The largest earthquake ever recorded in Kansas—a 4.9 magnitude temblor that struck northeast of Milan on Nov. 12, 2014—has been officially linked to wastewater injection into deep underground wells, according to new research from the U.S. Geological Survey (USGS).

The epicenter of that extremely rare earthquake struck near a known fracking operation.

The Wichita Eagle noted from the study that this man-made quake, which hit 40 miles southwest of Wichita and felt as far away as Memphis, likely came from just one or two nearby wells. The publication ominously noted that, “one of those two wells, operated by SandRidge Energy, is still injecting water at the same level as when the earthquake occurred two years ago.”

The USGS scientists believe that the 4.9-magnitude earthquake was triggered by wastewater injection for the following reasons:

  • There had not previously been similar earthquakes in the area.
  • There were waste-water injection wells nearby.
  • The earthquake activity started after the amount of water injected in the wells increased.
  • There’s a piece of earth that could be activated by changes in pressure.

Kansas has had a long history with fracking. In fact, the first well ever fracked in the United States happened in 1947 in the Sunflower state. The process is now used for nearly all of the 5,000 conventional wells drilled in Kansas every year.

But just like Oklahoma, Kansas is seeing an alarming uptick of “induced” earthquakes connected to the underground disposal of wastewater from the fracking process. Kansas is a region previously devoid of significant seismic activity, however, the number of earthquakes in the state jumped from only four in 2013 to 817 in 2014, The Washington Post reported.

According to an August report from The Wichita Eagle, Kansas has seen fewer and weaker earthquakes following the Kansas Corporation Commission’s recommendations to reduce underground injection of oilfield wastewater.

Incidentally, the Milan quake and the record-breaking 5.8 earthquake that struck Pawnee, Oklahoma last month occurred on faults that scientists did not previously know existed.

“If the well is in the right place next to a fault and the fault is oriented the right way, a little change in stress could cause (an earthquake) to occur,” USGS geologist George Choy, the study’s lead author, told The Wichita Eagle.

The study will be published in Seismological Research Letters next month.

“The source parameters and behavior of the Milan earthquake and foreshock–aftershock sequence are similar to characteristics of other earthquakes induced by wastewater injection into permeable formations overlying crystalline basement,” the study abstract states.

SandRidge Energy is the largest oil producer in Kansas and the largest disposer of wastewater in Oklahoma. In January, the Oklahoma-based company refused to abide by the Oklahoma Corporation Commission’s recommendations to shut down or decrease wastewater injection in order to prevent more earthquakes. The company agreed to shut down wells and reduce wastewater volumes months later.

The ‘Holy Grail’ For Earthquake Scientists Has Been Accidentally Destroyed

The ‘Holy Grail’ For Earthquake Scientists Has Been Accidentally Destroyed

Scientists once had a favorite curb in Hayward, CA. The curb sits at the corner of Rose and Prospect Streets, and has drawn in hordes of geologists, seismologists, and students over the years. They studied it because it lay on the Hayward fault line and was being pulled apart each year.

This evidence of Earth’s shifting plates was observed from the 1970s till 2016 when the city decided to fix the sidewalk & unknowingly ruined it.

Carbon dioxide concentration in the atmosphere stayed above 400 parts per million (ppm) during September—a time when CO2 levels typically hit the yearly low—raising fears that the planet has reached a point of no return.

“Concentrations will probably hover around 401 ppm over the next month as we sit near the annual low point. Brief excursions towards lower values are still possible but it already seems safe to conclude that we won’t be seeing a monthly value below 400 ppm this year—or ever again for the indefinite future,” Ralph Keeling, director of the CO2 program at Scripps Institution of Oceanography, wrote in a blog post.

The increase in CO2 levels runs parallel to a marked increase in global temperatures.

Three decades after the worst nuclear power plant catastrophe in history, a site in Chernobyl is being reimagined as a solar energy farm—one that would be the world’s largest once built.

The 1986 meltdown, which released radiation at least 100 times more powerful than the radiation released by the atom bombs dropped on Nagasaki and Hiroshima, rendered roughly 2,600 square kilometers of the area unsuitable for habitation. Greenpeace found that animals living within the exclusion zone have higher mortality rates, increased genetic mutations and decreased birth rate.

But in a twist of poetic justice, the Ukrainian government has expressed ambitions to turn 6,000 hectares within Chernobyl’s “exclusion zone” into a renewable energy hub. The proposed plant would generate 1-gigawatt of solar power and 400-megawatts of biogas per year, the Guardian reported. The country is pushing for a six-month construction cycle.

According to PV-Tech, ecology minister Ostap Semerak has visited the European Bank for Reconstruction and Development (EBRD) with the plan. The proposal has since been issued to investment firms in the U.S., Canada and the UK. If it gets the green light, the renewable energy farm will generate about a third of the electricity that the former nuclear plant generated when it was running.

“The Chernobyl site has really good potential for renewable energy,” Semerak said during an interview in London.

“We already have high-voltage transmission lines that were previously used for the nuclear stations, the land is very cheap and we have many people trained to work at power plants. We have normal European priorities, which means having the best standards with the environment and clean energy ambitions.”

Semerak said that two U.S. investment firms and four Canadian energy companies have already expressed interest in the Chernobyl’s solar potential, the Guardian reported. The project is estimated to cost between $1 and $1.5 billion.

“The EBRD may consider participating in the project so long as there are viable investment proposals and all other environmental matters and risks can be addressed to the bank’s satisfaction,” an EBRD representative said.

However “nothing is imminent,” the spokesperson added. “We are keeping an open mind. But it’s important not to read too much into it at this stage.”

“The Ukraine has indicated it will open the exclusion zone, and we welcome that. Renewables are one of our priorities, and as soon and as long as they secure investment then we will discuss the project and provide co-financing,” the bank rep said.

The renewable energy project isn’t just good news for the environment, it will provide Ukraine some energy independence, as the country currently gets the bulk of its natural gas from Russia, Business Insider pointed out.

If construction is approved, Chernobyl’s solar farm will hold the title of “World’s Largest Solar Plant” before Dubai’s massive concentrated solar plant catches up to it.

The Dubai Water and Electricity Authority (DEWA) has announced the second phase of a massive solar project located in the Mohammed bin Rashid Al Maktoum Solar Park. The 13-megawatt first phase of the project has been operational since October 2013 and the 200-megawatt second phase will be operational by April 2017. The facility will ultimately produce 1,000 megawatts by 2020 and 5,000 megawatts by 2030, which will provide power for 800,000 homes. The solar park will help reduce 6.5 million tonnes of carbon emissions annually, the release said.
