Moderate earthquake hits Japan, normal chances it is a foreshock

 

This is a beautiful clean subduction zone, and we know that these things need an M9 every 300 years or so, to do a thorough sweep-out.  

The last big earthquake in Japan had an M7 foreshock, and the odds are the usual 1 in 100.  It's always a good time to practice the drills.  I would paste my 2-buck accelerometers all over the place, but then, I would actually have them.  I'm working on it, but it is too much like work.

Since this earthquake is right at the bend, the M9 could rip north or south.  Most likely nothing at all, so I'm not going to strain my brain on this.

This is the one service I would miss if tumpy gets rid of the place.  Although the busgus is always wrong, they are more comprehensible than any other service.
