Recent Earthquakes in Oklahoma
Residents of Pawnee, Oklahoma got a rude awakening 7:02 a. m. Saturday morning (9/3/16) as a 5.6 magnitude earthquake shook the area. Fortunately, there are no reports of any injuries or deaths and property damage was minimal. A historical building, however, did shed a layer of limestone, but it is unknown whether any structural damage occurred.

This quake comes on the heels of a United States Geological Survey (USGS) report showing reduced quake activity in Oklahoma, down from 592 to 461 to date in 2016. This reduced activity is seen as the result of the Oklahoma Corporation Commission’s (OCC) new regulations limiting the injection of wastewater in targeted areas by 40%.

Conclusion: “The majority of recent earthquakes in central and north-central Oklahoma are very likely triggered by the injection of produced water in disposal wells.” 2015 Report of the Oklahoma Geological Survey (OGS) can be found HERE.
Texas and the Environmental Protection Agency
The Environmental Protection Agency’s annual evaluation of the Texas Railroad Commission’s oversight of disposal wells (Report dated 8/15/16) concluded that “there is a significant possibility that North Texas Earthquake activity is associated with disposal wells.” The 61-page Report devoted one page to the earthquake activity and did not include any scientific evidence. Furthermore, the Report applauded the Texas Railroad Commission’s efforts as reflecting “…an outstanding enforcement monitoring program.”
