Oklahoma maintains very high earthquake rate
This is sad for me, but there is now a chance for the M7 before the election. Will that make any difference? At this rate, we expect several 4's a week, an m5 once a week, and a 6 once a month. I have found that the higher magnitudes are 'jamming together'. In other words, it requires very few 5's to allow a 6, and maybe less 6's for 7.
The physics behind this is that the fractal dimension changes with scale. This could happen in granite, riddled by old faults. The extreme case is that of 'characteristic' earthquakes, where there are only surprise 6's and 7's and nothing smaller. Italy is something like that, and the smooth subduction faults.
ps. Natural gas futures are zooming.When El Nino finally leaves, we are going to freeze, and all that nice gas makes OK shake.
ps2. an m4 every day. I remember long ago when an m3 was big deal. :)
