A noteworthy magnitude 4.3 earthquake has struck a central Oklahoma fracking operation.
This comes on the heels of additional craton movement which was documented this morning in another post regarding this current midwest earthquake unrest.
Also, yesterday (June 13 2015) another noteworthy M4.0 earthquake struck a different fracking operation in Alberta Canada (far to the NW of Oklahoma).
The earthquake forecast issued on June 10, 2015 specifically called for midrange to upper 4.0M earthquake activity to resume. See the forecast for Oklahoma / Kansas region here:
Now the midwest earthquake activity begins in earnest after we saw a 4.0M strike at the CANADIAN fracking operation in the Pacific Northwest.

Additionally, on top of the 4.3M fracking earthquake in Oklahoma, another earthquake just subsequently struck on the West coast of the United States (in California). The West coast earthquake occurred along the nearly same latitude as the fracking earthquake.
Both the fracking earthquake, and the following California earthquake occurred near the 36th parallel (North Latitude), both at an approximate depth near 5.2km, with a time about 17 minutes apart.
This California earthquake occurred at a dormant volcano “creatively” named “Volcano Peak“.
Volcano peak is clearly on the move, showing multiple mid-range M3.0 activity, and now a swarm of earthquakes over the past few weeks.
This volcanic chain is part of the Coso Volcanic field, which last erupted 40,000 years ago. Clearly volcano peak has erupted in the past few hundred / thousand years since the main Coso Field eruption.
________
As we saw earlier today in the Pacific Northwest , there was a back and forth volley of seismic activity between the fracking operation in Canada, and the dormant volcanoes along the West Coast.
No doubt the craton is under pressure, due to release in the Pacific Northwest very soon.

UPDATE: 240pm CDT June 14, 2015:
After making the above post, another earthquake struck the exact same location in Oklahoma.
Ironically, just like the West coast volcanic earthquake.. this newest Oklahoma earthquake was a M3.7 at the same depth near 5.2km.
M3.6 – 21km W of Perry, Oklahoma
