Hi Chris-

I mention this, almost tongue in cheek, but last night was a Full Moon.  I am merely noting it, nothing more.  It's going to be interesting to watch the aftershock pattern. Two initial events, with a third almost as strong.

It looks like there was about 19/20 "pre-events," all less than M1.0, leading up to the first M5.7, starting just after 10:19 PM.
The first M5.7 hit at 12:18 AM.  They've also updated the moment Tensors to show a magmatic component, which is interesting, but not unexpected.
