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 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.
At first glance, you wouldn't think avocados and almonds could harm bees; but a closer look at how these popular crops are produced reveals their potentially detrimental effect on pollinators.
Migratory beekeeping involves trucking millions of bees across the U.S. to pollinate different crops, including avocados and almonds. Timothy Paule II / Pexels / CC0<p>According to <a href="https://www.fromthegrapevine.com/israeli-kitchen/beekeeping-how-to-keep-bees" target="_blank">From the Grapevine</a>, American avocados also fully depend on bees' pollination to produce fruit, so farmers have turned to migratory beekeeping as well to fill the void left by wild populations.</p><p>U.S. farmers have become reliant upon the practice, but migratory beekeeping has been called exploitative and harmful to bees. <a href="https://www.cnn.com/2019/05/10/health/avocado-almond-vegan-partner/index.html" target="_blank">CNN</a> reported that commercial beekeeping may injure or kill bees and that transporting them to pollinate crops appears to negatively affect their health and lifespan. Because the honeybees are forced to gather pollen and nectar from a single, monoculture crop — the one they've been brought in to pollinate — they are deprived of their normal diet, which is more diverse and nourishing as it's comprised of a variety of pollens and nectars, Scientific American reported.</p><p>Scientific American added how getting shuttled from crop to crop and field to field across the country boomerangs the bees between feast and famine, especially once the blooms they were brought in to fertilize end.</p><p>Plus, the artificial mass influx of bees guarantees spreading viruses, mites and fungi between the insects as they collide in midair and crawl over each other in their hives, Scientific American reported. According to CNN, some researchers argue that this explains why so many bees die each winter, and even why entire hives suddenly die off in a phenomenon called colony collapse disorder.</p>
Avocado and almond crops depend on bees for proper pollination.

Many have opted to salvage what partial colonies survive and move away from agricultural areas.</p><p>The future of pollinators and the crops they help create is uncertain. According to the United Nations, nearly half of insect pollinators, particularly bees and butterflies, risk global extinction, Phys.org reported. Their decline already has cascading consequences for the economy and beyond. Roughly 1.4 billion jobs and three-quarters of all crops around the world depend on bees and other pollinators for free fertilization services worth billions of dollars, Phys.org noted. Losing wild and native bees could <a href="https://www.ecowatch.com/wild-bees-crop-shortage-2646849232.html" target="_self">trigger food security issues</a>.</p><p>Salazar, the beekeeper, warned Phys.org, "The bee is a bioindicator. If bees are dying, what other insects beneficial to the environment... are dying?"</p>

Australia is one of the most biodiverse countries in the world. It is home to more than 7% of all the world's plant and animal species, many of which are endemic. One such species, the Pharohylaeus lactiferus bee, was recently rediscovered after spending nearly 100 years out of sight from humans.
Scientists have newly photographed three species of shark that can glow in the dark, according to a study published in Frontiers in Marine Science last month.
