An unintended natural experiment

The highlighted paragraph below shows the result of two different "theories" of ways to reduce the number of human-caused earthquakes.

Quote:

The area where the quake was centered is on the edge of a region covered by a "regional earthquake response plan" issued in March by the Corporation Commission, whose goal was to cut the number of earthquakes by reducing wastewater injection volume by 40 percent from 2014 levels. Oklahoma was late in imposing volume limits, taking a different approach than Kansas after both states had an uptick in quakes in the first half of this decade. Kansas moved quickly to limit volume while Oklahoma concentrated on the depth of the disposal. Kansas saw a 60 percent drop while the frequency of quakes in Oklahoma continued to climb.
