Oklahoma Earthquakes Linked to Injection Of Fracking Wastewater Called Security Issue

摘要

In the months after Sept. 11, 2001, as U.S. security officials assessed the top targets for potential terrorist attacks, the small town of Cushing, Okla., received special attention. Even though it is home to fewer than 10,000 people, Cushing is the largest commercial oil storage hub in North America, second only in size to the U.S. government's Strategic Petroleum Reserve. The small town's giant tanks, some big enough to fit a Boeing 747 jet inside, were filled with around 10 million barrels of crude at the time, an obvious target for someone looking to disrupt America's economy and energy supply.
