Magnitude 8 earthquakes, just hanging out

These earthquakes are the 'joy riders' or 'surfer dudes' of plate margins.  They can cluster and mean nothing.  However, they do set up the 9's.  Here you can see the irregular plate margin and you know that it never come up with anything more than an m8.5  An m9 is 10 times longer than those little splotches.

So, nothing super-duper is coming.  It sucks for the locals in stone houses, but they'll learn.
