This is the 3rd Oklahoma fracking field earthquake in the past 24 hours. Today, across the state, from Central OK to Northern OK, we’ve seen a series of earthquakes progressing steadily.
Previous two earthquakes from today (Oct. 8 2013) documented here:

36.714°N 98.012°W depth=5.0km (3.1mi)
- 26km (16mi) WSW of Medford, Oklahoma
- 37km (23mi) NNW of Enid, Oklahoma
- 82km (51mi) W of Ponca City, Oklahoma
- 94km (58mi) WSW of Arkansas City, Kansas
- 145km (90mi) NNW of Oklahoma City, Oklahoma
In the past, in these VERY same areas, we’ve seen 4.0M + 5.0M earthquakes occur directly at similar pumping operations. At the time (2011 into 2012) these 5.0M earthquakes caused damage in Arkansas, Oklahoma, and Colorado.
I would suspect further more sizable movement over the next weeks, due to this current flurry of activity across the edge of the North American Craton (plate). Yesterdays east coast 4.5M (off the shores of South Carolina) indicate pressure across the whole of the plate.
The pressure translating into moderate earthquakes at areas we expect to see very LITTLE movement occur ‘normally’ (if there even is such a thing as normal when it comes to what is occurring currently).
