February 2015 – OKLAHOMA – 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. As the volume of drilling waste pumped underground has grown, the number of earthquakes with magnitude 3 or higher has increased. In particular, as the drilling has intensified along the northern border, the quakes have followed. The Prague 5.6 magnitude quake in 2011 had one 4.8 magnitude foreshock and one 4.8 magnitude aftershock.

The Prague 5.6 magnitude quake had one 4.8 magnitude foreshock and one 4.8 magnitude aftershock. Altogether there were 63 quakes of magnitude 3 or higher, concentrated mostly in the center of the state, where the 860 million barrels of waste pumping was centered. Drilling activity increased in northern Oklahoma but the 34 earthquakes of magnitude 3 or greater remained concentrated in the center of the state. Waste pumping increased to more than 1.2 billion barrels, with a big increase in the north. Earthquakes surged with 106 magnitude 3 or greater, including a string of quakes in the north of the state, where waste pumping also increased as the statewide volume rose to more than 1.5 billion barrels. The rate of quakes multiplied with 567 jolts at least magnitude 3 with the heaviest concentration in the northern end of the state. Waste-pumping data for 2014 is not yet available. –Washington Post
