Oklahoma earthquake summary - July 2015
I'm really going to say that the rate of increase of magnitude is down. Kansas is enjoying a summer holiday, but Ok. City had a big flurry last week. It's interesting to think how the rate should go up as the earthquakes become larger. Since the magnitude scale is exponential, and the fault area goes by the square, some things should slow down. Stress corrosion would go on a steady rate if the pumping of surface water is steady. At the beginning of this whole thing, I'm sure the pumping was increasing exponentially. Now, I have no idea what is going on.
But we see more clusters, at places where they aren't even pumping, just because the whole thing is one mechanism. There is also the 'tipping bucket' effect when the whole thing just goes, much like a landslide. The big experiment continues, and it is fascinating.
