Rodekyll , tell me where that shaker started

[oldbike54]

One near Enid, then a bigger one (4.2) near Crescent OK.

The USGS says the frequency of shakers will increase in the area from OKC to DFW because of waste water innection wells (not the same as fracking)

[oldbike54]

 There has been some effort to stop fracking and injection wells here , at least the problem has been recognized which is a start . Most of the activity is well (pun intended) West of me , but the larger shakers are felt even over in Eastern OK.

I agree with Rode on the well plugging technique.

As a geophysicist, with quite a bit of seismic and a bit of earthquake knowledge I find the phenomena fascinating.  Personally I think the chance of a larger than 4-5 Richter scale quake to be small.  But, not impossible:  OK lies at a triple junction area, with an intra-cratonic old plate merge suture.  Hence, if enough stress built, yes there could be a fairly big event.  Hang on tight, and don't stack empty wine bottles on top of your kitchen shelves (I learned that living in Anchorage, AK).

  This is not what Hemmingway meant when he wrote about the earth moving.

To put the OK fracking into perspective, that north Korean 'H-bomb' test looks identical to fracking on a seismograph -- same sort of Richter and depth signatures.

Oh, Gawd - Okies with nukes! Be VERY afraid!!!

For how long has this been happening in OK?  Just recently as in the last year or quite some time before that?  Any coincidence in the abandoning of wells due to low oil prices and pumping being discontinued?

 10 years or so Paul .

Has fracking been around that long?
