>> A five point O earthquake striking in the heart of US fracking country. Authorities saying the quake hitting Sunday near cushing, Oklahoma about 50 miles from Tulsa, is among the most powerful in the state recently. No one was hurt but it left Broken glass and chunks of concrete in its wake.
Cushing is considered a hub for crude oil shipment, and houses a network of intersecting oil pipelines. Authorities there evacuated downtown due to gas leaks and infrastructure inspection. A flurry of seismic activity has fueled growing concerns about underground energy production in the region. A report from the state's geological survey last year said the earth quakes were linked to the practice of injecting waste water from oil production into the ground.
