The <entity_0> was a 5.7 magnitude intraplate <entity_1> which occurred near Prague, <entity_2> on November 5 at 10:53 p.m. CDT (03:53 UTC November 6) in the U.S. state of <entity_2>. According to the United States Geological Survey (USGS), it was the most powerful <entity_1> ever recorded in <entity_2>; this record was surpassed by the 2016 <entity_2> <entity_1>. In March 28, 2016 the USGS released the USGS National Seismic Hazard Map which concluded that the primary cause of the <entity_1> in <entity_2> in 2011 was pressure on faults from cumulative effects of injecting oil drilling wastewater under high pressure into the underground. The <entity_2> Geological Survey believes the <entity_1> occurred along the Wilzetta Fault, which is also known as the Seminole Uplift. The <entity_2> Geological Survey reported in 2011 that a minor <entity_1> swarm which occurred in January 2011 could possibly have been due to hydraulic fracturing, which is a process used to extract oil from oil wells.
