The article said the USGS said the area has been dead for seismic activity for some time, which surprised me. The largest "felt" earthquake in OK was in El Reno, due south of Kingfisher, many years ago, but the last measurable small rumblings were just in May 2005.
If you go to the OGS (Oklahoma Geological Survey) website, there's a slide show-type program showing mapped locations in OK of all the more noticeable seismic occurrences since 1977 thru last year, I believe. A majority of them have occurred in the area of El Reno, with one major in Kingfisher in mid 1980s--I think it was either 1984 or 1987.
Anything I could think of (my theory was a nearby new well being drilled perhaps loosening some underground formation with a gas trap adjacent--but now we know it's following a surface formation--the creekbed--so that's out) -- wouldn't touch all the things that the consulted experts must have ruled out already.
It's a real mystery! (And I don't remember your FST reference, just "Don't Crush that Dwarf, Give Me the Pliers" and "Antelope Freeway, 1 mile ... Antelope Freeway, 1/2 mile ... Antelope Freeway, 1/4th mile ... Antelope Freeway, 1/8th mile ...".)
