The Oklahoma earthquake swarms are an ongoing series of human activity-induced earthquakes affecting central Oklahoma, southern Kansas, northern Texas since 2009. [6] [7] [8] Beginning in 2009, the frequency of earthquakes in the U.S. state of Oklahoma rapidly increased from an average of fewer than two 3.0+ magnitude earthquakes per year since 1978 [9] to hundreds each year in the 2014–17 ...
The following is a list of historical earthquakes with epicenters located within the boundaries of Oklahoma. Only earthquakes of greater than or equal to magnitude 4.5 are included.

Environmental Protection Agency illustration of the water cycle of hydraulic fracturing. Fracking in the United States began in 1949. [1] According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.
Maryland introduced a temporary fracking ban in 2015, [117] which was made permanent in 2017. [118] [119] Washington joined these states by banning hydraulic fracturing in May 2019. [120] A type of fracking technique called slickwater fracking was used in Texas in 1998 to complete natural gas wells in the Barnett Shale. [121]
