Oklahoma's dramatic rise in earthquakes seems related to oil, gas, fracking and reinjection

CNN is reporting on a sharp increase of earthquakes in Oklahoma that seem to be related to fracking, especially the process of filling “underground injection wells” with water, which may destabilize old faults.
Areas of the state that saw only one or two measurable quakes a year now see hundreds.  One woman reported having to leave her home, and people are buying earthquake insurance. 
The strongest quakes have been in the 5.5 area range, enough for some damage.  This is comparable to the quakes in central Virginia in August 2011. 
The story is by Marlena Baldacci and Mariano Costillo, link here and includes a video interview.

The energy industry accounts for one out of six jobs in Oklahoma. 

Truthloader offers the video above, giving more explanation.  Some quakes occurs at some distance from the actual wells.

The problem is increasing in many other states.  But the southern part of the Mississippi Basin is over the “New Madrid Dimple”, and is susceptible to earthquakes (and a few large ones occurred in the nineteenth century).
