Earthquake of 4.2 magnitude in fracking region

From the Posting by Michael Janitch on December 16, 2013

Kansas, which not normally very seismically active, is showing signs of the surrounding pressure building in Oklahoma and Texas.

On December 16th 2013, a 4.2 magnitude event struck directly near a KANSAS injection well. This current earthquake falling across the border from Oklahoma, happening just 0.3 miles away from the nearest well head.

For Kansas (and the midwest USA), this is noteworthy. Now we’ve seen movement across the ENTIRE craton edge. (The “craton” is the border of the bedrock [basement rock] of the major portion of North America, along the west and south.)

The movement began on the West Coast (5.5M off the coast of Oregon on December 2), followed by an earthquake swarm in Oklahoma / Texas (December 5th – 7th), followed by a Yellowstone earthquake swarm (December 9), followed by a fracking earthquake at the Colorado New Mexico border (December 10th) , followed by a Eastern Craton edge earthquake at the Tennessee Georgia border (December 10th), followed by a Northeast Craton edge quake in Southeast Canada (December 11th), finally followed by this Kansas 4.2M event today (December 16th).

Be prepared for additional movement in nearby adjacent areas, near term.
