I did say they would have to be over M5, and in the right zone. This was almost there. I don't really count the outer zone, but I am very fascinated on what is happening near the armpit. The earthquakes here are operating at full fractal, which means a straight line log-log plot of frequency - mag (which is log). That means there are x number of M3's for an M4, and x again for M4 to M5, etc. I am still expecting the last M7.5 on the right strike-slip track to hit the armpit by the end of this year.
