Ask HN: What are you doing for earthquake preparedness?

There's a 76% probability of a M>=6.7 occurring in Northern California within the next 30 years according to the 2015 UCERF3 model. As someone looking to lay down roots in the Bay Area, and how most houses in SF are matchsticks stuck into sand dunes, these numbers scare me to no end.

I see people paying $3mn for old Victorians with brick foundations, it seems completely illogical. What can a sane person do to protect their house and family against odds like this?
