“Methinks San Andreas is the next “Big One”
By the Big One, if you mean a whimper. San Andreas can barely cause 8 mag, but Cascadia is a subduction zone capable of 9.2 mag. So the Cascadia is 80 times bigger than the biggest San Andreas can produce.
If earthquakes can have a conference, San Andreas is not even allowed to enter as a significant other.
8.0 to 9.2 is 16x, not 80x.
Hayward fault could be a problem for the S.F. Bay area.
