Oklahoma and Kansas are having some m4's. But I like this m5 out off-shore.
By themselves, these are just rare events, but there is physics behind the fact they could be related. We expect the deep basement to go into fits and starts. The coast is sinking, partly due to left-over ice age stuff, and partly due to a cooling passive margin. These things put on strains.
None of this actually means anything, but I expect some more regional activity for a while. Get your seismometers made!
