Shaken more than 560 times, Okla. is top state for quakes in 2014

Oklahoma had a fivefold surge in earthquakes last year, making it by far the most seismically active state in the Lower 48.

The Sooner State was shaken by 564 quakes of magnitude 3 and larger, compared with only 100 in 2013, according to an EnergyWire analysis of federal earthquake data. California, which is twice the size of Oklahoma, had fewer than half as many quakes.

But, but, but frackening = freedom!
