After reading this, I searched for and found this report on earthquake impact from 2018 (for both "the big one" and a smaller, 6.8 portland hills quake), I believe based on the OP referenced data:
That is terrifying! What's interesting is the damage from the 6.8 magnitude Portland Hills Fault earthquake is simulated to be much greater for me than the 9.0 Cascadia Subduction Zone earthquake.
