Over the past 7 days, we’ve seen a large increase in movement across the South to Northwest edge of the North American Craton.
The transferred pressure (coming from the WEST), is having a ‘spillover’ effect, cascading small to moderate earthquakes across the defined edge of the North American plate.
Oklahoma, already a weak spot, now further weakened by literally thousands of deep injection / extraction wells, which penetrate the cratons edge — attempting to extract natural gas from the shale deposits, also DISPOSING of waste water via old oil wells. Add in a bit of carbon capture into the mix as well, all combining to form a “perfect geo-seismic storm”.
First, we see single, moderate earthquakes in the 3.0M to 4.0M range occur at the fracking operations in OK, and AR. Then, following the moderate movement, we usually see a series of individual smaller 2.0M quakes, subsequently followed by a swarm as we’re seeing now. Ultimately, following the frack quake swarms, we usually see a few borderline 5.0M events occur anywhere along the edge of the plate, from the East coast through the south-midwest (OK and AR), all the way Northwest .
Over the past several months, Yellowstone has jumped into the Craton Edge earthquake mix. Showing mid 4.0M activity across Idaho, and Wyoming (again, following midwest fracking earthquake swarms).
Here are all my previous posts regarding fracking induced earthquakes :
