Fracking wastewater well linked to Ohio earthquake

An earthquake in Ohio on New Year's Eve was caused by the injection of fracking wastewater, an expert report has concluded. The magnitude 4 temblor was the latest in a series of small quakes centered around the 1.7-mile-deep wastewater disposal well outside Youngstown. A Columbia University seismologist said the quake was caused when the injected water created pressure on a fault line. The well along with four others within a five-mile radius will remain closed until an assessment is completed.
