Latest Earthquake May Link to Disposal Well
The U.S. Geological Survey reports a 3.4 magnitude earthquake has been recorded near Prague in central Oklahoma. The Lincoln County Office of Emergency Management says there were no injuries or damage reported.
The USGS says the quake was recorded at 12:24 p.m. yesterday about 6 miles northwest of Prague. That's about 40 miles east of Oklahoma City.
StateImpact reports Prague was the scene of the state’s largest earthquake in at least a century, a 5.6-magnitude November 2011 temblor that damaged buildings more than 60 miles away. Research by University of Oklahoma seismologist Katie Keranen shows that disposal wells used by the oil and gas industry likely triggered the 2011 quake. She says yesterday's quake is near the first rupture in the November 2011 earthquake sequence near Prague.
