An earthquake of 5.0 magnitude occurred on Sunday, 6 November near the Oklahoma town of Cushing. "[T]he largest crude oil storage facility in the world" lies near the town; a U.S. Geological Survey report published in 2015 had warned of the potential for damaging earthquakes near Cushing. Oklahoma and Kansas have been experiencing numerous earthquakes, mostly minor, since 2009. Figures from ABC News show an increasing frequency of earthquakes:
The USGS recorded 1,010 earthquakes of a magnitude 3.0 or greater in the region last year, nearly three times as many as the 318 temblors of this magnitude in 2009. Oklahoma alone felt 619 quakes of a magnitude 2.8 or larger from January through June of this year.
The strongest recorded in Oklahoma, of magnitude 5.8, happened on 3 September. Underground disposal of waste water from the oil and gas industry is believed to be a cause of the seismicity; there is also speculation that hydrofracturing is a factor.
There were minor injuries and several buildings were damaged; no damage to the area's pipelines has been reported. Schools in the area are to be closed Monday, so they may be checked for damage.
