I was just looking at this again..
21 quakes..aftershocks.. whatever.. starting with the 7.3.

They are all in the same general area as the 7.3 except for one to the northwest a bit.
The quakes are usually spread out randomly. This is different.

If you go to the end of the simulation.. it will list them all for rollover view.

There hasn't been anything over a 7 since july of 2011..
I don't think this is over, considering this..
