Even for California to get a 6.4 one day and a 6.9 the next is kind of scary

Especially if they are in the same place. What's tomorrow? A 7.5 in Ridgecrest? So, though this might be the end of the really big quakes, especially in this one area, it might not be also. Also, this is going to cause pretty big earthquakes likely in other places on earth because of  the way the plates work when this kind of energy is released in one place it is going to release energy other places too.
