Lots more Oklahoma earthquakes
As we all know by now, these earthquakes are triggered by irresponsible injection into the Precambrian megathrust. These are huge features that run right through Eastern North America, although you would never know it from any US geology. The megathrusts are highly stressed, and only lacking in water to make good earthquakes.
So, you can tickle the tails of these tigers to trigger small earthquakes, but how big can you get? OK now has the record at M5.6. But access to deep water is not totally caused by Man, it can happen naturally as well. Thus, we must include the larger M7's of New Madrid.
Anyway, I wasn't going to write any more about this until my expected M5. This will open up the central thrust zone, and start a full growing baby New Madrid. In the meantime, the injector people are enjoying the fact that the fractures are opening up to accept more water. They are making money hand over fist.
