Huge earthquakes hit Oklahoma
I sort of did predict this, since the Stillwater train track (fault) was blocked. Strain energy is like water, it has to flow somewhere. Anyway, since this was at the butt end of the northern fault, it was a mixed normal earthquake. That's means that somewhere else it was recorded as an M5.8, but it only gave wussy ground motions in OK. The next earthquake up the fault will be pure strike-slip, and then we'll see some PGV. Too bad my Happy Happy Shake Meter is still on the drawing board. :)
If the earthquake express train goes right up the fault, then this will provide a way around the Stillwater blockage, and we'll get some strain down to Cushing.
