The whole of the North American Craton was displaced over the past 24 hours (up to 845am CDT June 14, 2015).
The graphic below speaks for itself, showing a 4.0M fracking earthquake along the NW edge of the plate in Alberta Canada, followed by earthquakes further South , 50 miles East of Mount Adams + Mount Rainier Volcanoes in Washington State, and at Clear Lake Volcano in Northern California.
In addition to the earthquakes at multiple volcanoes, we see a new swarm has developed at the Oklahoma fracking operations, and a more rare earthquake swarm developing along the New Madrid Seismic Zone (NMSZ).
In the most recent earthquake forecast, I fully discussed the activity to expect along the craton edge, and explain how the earthquakes are transferring along the “edge” of the unsubducted plate.
The movement seems to be happening in a pattern extending from the Northwest to the Southeast, producing noteworthy earthquakes along the boundaries between older, and younger plate regions.

Below is a past example of craton movement caused by West coast earthquake activity.
The screenshots below show earthquakes on the West coast preceded midwest earthquake activity by a few days (or less), and eventually caused a New Madrid Seismic Zone Earthquake following the pressure transfer as it passed EASTWARD.
As the pressure transferred East, it released at “weak points” producing earthquakes at dormant Volcanoes along the West coast, also produced activity at the Fracking operations in Colorado + Oklahoma, finally terminating with a single event along the New Madrid Seismic Zone.
