A lawsuit claims that Oklahoma’s great increase in earthquake activity has been caused by pumping waste from drilling operations back underground. The suit involves the largest measured quake in the history of the state, a 5.6 tremor that happened in Prague, east of Oklahoma City in November 2011. The pace of quakes with magnitude 3 or higher has increased since then, with 567 in 2014, and 52 in less than four weeks this month.
