RALEIGH -- Earthquakes have rocked Oklahoma in recent months and it's believed that hydraulic fracturing is the cause. Fracking, as it's known, is the process of extracting oil or gas from the ground. Scientist for the US Geological Survey Arthur McGarr says it's the wastewater byproduct that is actually causing the quakes. He says man-made earthquakes can be damaging.

McGarr said, "Oklahoma hardly had any earthquakes at all, until this recent oil and gas boom that started in about 2009."

Earlier this month Governor McCrory signed North Carolina's new fracking legislation into law. The McCrory administration says the industry will likely bring as many as 500 new jobs to the state over the next seven years and generate $80 million in new income. For now the waste-management method of injecting wastewater into the ground is not planned in North Carolina.
