In the Wilmington oilfield at Long Beach, California, an area 50 square kilometres subsided. In the centre of the subsidence area the maximum subsidence was 9 meters. The removal of liquids from underground reservoirs results in a reduction of fluid pressure which causes the pore spaces to close and the sediments to compact, resulting in subsidence. As the sediments compact the rock above it also subsides. Under certain circumstances, such ground movements can induce earthquakes.
In Oklahoma's situation, oil pumping, fracking and fluid injection into oil wells are very likely candidates for the causes of earthquakes experienced there.
