Gather NewsWhat could have caused the Oklahoma earthquakes that occurred on Saturday? Both tremors were centered just east of Oklahoma City. The second quake, late Saturday night around 11 p.m., lasted more than a minute and could be felt as far north as Kansas City, Missouri, and as far south as Dallas, Texas.
According to the US Geological Survey, more than one earthquake shook the region. The first one was a magnitude of 4.7. A series of smaller ones clocked in around the 3.0 range, and the last one rattled windows at 5.6 on the Richter scale. Normally, this region of the South and Midwest is relatively quiet in terms of earthquakes. But in recent years, there have been more and more. Why? Is it nature at work? Or is it something else?
The Oklahoma Geological Survey by Austin Holland was published recently, and it states clearly that fracking is one of the causes for earthquakes. When you inject the earth with saltwater to break up the shale beneath the earth, you're creating an instability in the crust that results in sudden and sometimes extreme movement. In other words, the earth sinks a little where the fracking occurs. Doesn't anyone see anything wrong with this? Oil companies are admitting they're damaging the earth, damaging homes, infrastructure, and possibly risking lives...all for the sake of natural gas and oil.
Just to illustrate the point, between 1977 and 2008, there were only 28 earthquakes in Oklahoma: less than 1 per year. Between 2009 and 2010, the state experienced 134 earthquakes: an average of 95 quakes per year. That's a huge difference. And it simply can not be attributed to a fault line or natural causes. Even the British energy company, Cuadrilla Resources, admits that fracking is the most likely cause of increased incidents of earthquakes in the area.
