Study: Major Oklahoma Quake Likely Caused by Oil Drilling Waste 
----------------------------------------------------------------


 
New research says oil drilling was likely behind a major earthquake that
struck Oklahoma in 2011. A study published Tuesday in the journal
Geology says the 5.6-magnitude quake was caused by oil waste being
pumped deep underground. The quake injured two people, damaged homes and
was felt across 14 states. It was the largest earthquake to hit the
central United States in decades and the largest ever recorded in
Oklahoma.
