There could be a larger one coming in Northern California if we look at past events regarding Tarapaca and Rat Islands...

This is what happened in 2005:

2005-06-13 7.8 Tarapaca, Chile
2005-06-14 6.7 Rat Islands, Aleutians
2005-06-15 7.1 Off coast of Northern California

Compare to now:

2017-10-08 6.6 Rat Islands, Aleutians
2017-10-10 4.1 Northern California (already)
2017-10-10 6.3 Tarapaca, Chile

Interesting to see if there is bigger one coming.
