Over the past week we’ve seen a flurry of 4.0M range earthquakes occur across Oklahoma, Kansas, and Colorado.
This midwest earthquake stress is producing more activity than the entire West coast combined!
During the same time frame (over the past week up to March 26 2015), we’ve also seen additional noteworthy seismic activity occur in Texas.
All of this aforementioned seismic stress has transpired at fracking operations located in each state.
Early this morning (March 26 2015) a rare magnitude 2.9 earthquake struck near Chicago Illinois. This Illinois movement is a sign of the greater stresses showing just one full state away in Oklahoma.
After the Chicago activity this morning, a new earthquake has just struck on the Eastern edge of the craton, in Tennessee.
Seeing movement transfer East across the plate is nothing new , as we have seen this occur several times over the past few years. Professionals are still ignoring this fact of earthquake pressure transfer for some reason or another.
It should now be obvious to even the average observer that Earthquakes in one area are causing earthquakes in adjacent areas .. sometimes far away from the swarm itself.
Usually pressure transfers from the NW to the SE then back to the NE along the edge of the craton. Earthquakes usually occur along the edge of the plate when pressure comes from the Pacific Northwest.
