Fracking And Earthquakes In Middle America | On Point with Tom Ashbrook
"The earthquakes of Oklahoma. There’s a sharp increase. Big oil, lots of water, pressure, fracking.
Until 2008, the state of Oklahoma averaged one or two earthquakes magnitude 3.0 or greater a year. Then the lid blew off those numbers. Rising year by year. To 20. Then 42. Then hundreds. Last year, Oklahoma had 585 earthquakes that size. This year, it’s on track for more than 700. Walls shake. Bricks fall."
