Okay, so this is the script so far. Death, in the form of a giant New Madrid earthquake is bored with Oklahoma. He thinks the tornadoes are having all the fun, so he leaves for a holiday.
For real, my current hypothesis is that injection of fresh water is causing chemical stress corrosion which is forming a new-New Madrid. That is why I am always tracking the health of the gas or oil freshwater fracking industry. The can inject all the deep 'produced water' all they want, since it is non-aggressive to quartz. New Madrid was a natural seep that probably took thousands of years to set up. OK is doing it a thousand times faster.
The last big action was in December, and a bit of leftover action in January due to the warm El Nino. But then a good freeze came, and freshwater fracking was shut down. It started again at the beginning of May and we had a good run of 3 M3's a day, with a 4 on the weekends.
It seems to be off again, and I can't figure out why. We know that they would lie like burgers*, about what they are injecting, but I can't see a reduction in this type of waste. The only way I get to save my non-existent reputation is if we have a big one soon. If it it totally peters out, I'll have to re-think my faith in basic physics. Perhaps join the philosophy club. Bah!
*I make up these things.
