Back once again to Arkansas. Another injection well induced earthquake…. a repeat, ongoing problem it would seem.

Now it appears they’re back up and running. This past winter (2012 going into 2013) Arkansas experienced a series of additional “frack quakes” as well as EXPLODING COMPRESSOR STATIONS AND PIPELINES.
This current 2.7M earthquake occurred inside an operation we haven’t seem much movement around in the past. Previous areas like Greenbrier / Beebe have had recent movement as well, however this Earthquake occurred inside operations to the North.
The Arkansas earthquakes, including movement in adjacent areas such as Oklahoma, Louisiana, and Texas — indicate heavy stress upon the edge of the North American Craton (plate). All the areas weakened by man made injection / drilling will continue to experience ‘unexpected’ seismic activity UNTIL the unrest in the West Pacific dies down.
The Pacific plate unrest could carry on for years to come, which means drilling points across the craton edge will continue to be in flux, much like perforated edges on a thick piece of cardboard.. they will tear at the weak points first.
