    Fracking caused the 5.7 earthquake. FACT

    News reports say scientists are blaming the oil extraction process called “fracking” for a 5.7 earthquake in the US state of Oklahoma two years ago.
    The BBC and Clean Technica and others report the practice led to the biggest earthquake ever in Oklahoma.
    While fracking has been a major factor in increasing US oil production, it also is blamed for polluting ground water and destroying wells across the country.
    Wikipedia says: “Hydraulic fracturing is the propagation of fractures in a rock layer by a pressurized fluid. Some hydraulic fractures form naturally—certain veins or dikes are examples—and can create conduits along which gas and petroleum from source rocks may migrate toreservoir rocks. Induced hydraulic fracturing or hydrofracturing, commonly known as fracing, fraccing, or fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas, and coal seam gas), or other substances for extraction.[1] This type of fracturing creates fractures from a wellbore drilled into reservoir rock formations.”
    The claim of responsibility for the Oklahoma quake comes from a study by Geoffrey Abers of Columbia University’s Lamont-Doherty Earth Observatory:
    “There’s something important about getting unexpectedly large earthquakes out of small systems that we have discovered here…the risk of humans inducing large earthquakes from even small injection activities is probably higher [than previously thought].”
    Bloomberg said researchers at the University of Oklahoma, Columbia University and the U.S. Geological Survey published their findings in the journal Geology. The scientists said the results show “the long-term risks the thousands of wells pose and shows a need for better monitoring and government oversight.”

    • I've lived in Texas for 54 years , NEVER heard of an Earthquake here until a couple of years ago ..... We've had about 20 since !!!!! Small ones , but still , this is a no-brainer for me , and I own oil and gas stocks so I am NOT making a "biased opinion" here , just stating some facts and my take on it ...... I think fracking is indeed very harmful to tectonics and ground water ..... air quality too ...... glad we found abundant energy , but we better watch out , because I'm not too sure this is is not going to cause some VERY serious problems , and once "done" cannot be "undone" ...... we live in a "dmd if ya do and dmd if ya don't" world

    • Earthquakes, massive releases of methane, pollution of ground water through fracking - yet, the "Green" types insist that NG is better for the planet than coal?!!! I don't get it.

    • From whom did you hear this, al gore ?
