Rare Kansas 4.7 magnitude earthquake (4.0M revised) @ Fracking operation
May 23, 2015 Michael Janitch
A noteworthy, and rare 4.7 magnitude earthquake has struck South Central Kansas at a fracking operation.
This is one of the larger earthquakes in Kansas state history.
The picture at the link does not show a well being fracced (the absence of the characteristic water tanks, pressure monitoring equipment and frac pumpers is a clue).
It does show 4 of the pretty much industry standard 400 bbl upright tanks used to hold produced oil/water until it can be trucked away, and what appears to be a pump jack. It looks like a producing oil well.
You can see where the hoses have been pulled across the containment dike to pump fluid out of the production tanks (north side berm, by the middle tanks), and the location is too small for frac equipment.
There are no tire tracks around the site indicating anything other than agricultural activity, except for the access road and highway approach.
Considering all that, I'm not sure fraccing has anything to do with the earthquake if this is the closest well.
