A 3.4-magnitude earthquake was recorded about 12:24 p.m. today, according to data from the U.S. Geological Survey.
The epicenter of the quake was located six miles northwest of Prague, at a depth of 9.3 miles, the data show.
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.
“Today’s earthquake is near the first rupture in the November 2011 earthquake sequence near Prague, and is likely on one of the faults associated with that earlier sequence,” she says. “The lack of an active local network precludes a precise determination of depth or correlation to a specific fault segment.”
