Looks like the worst is likely over with the LA wild fires. I stumbled on this fire hazard map of SoCal. The warning sign has been flashing red for years:
Back to the Bay Area, here is our fire hazard map. Pretty much the entire Oakland hills is in red. The hilly part of Belmont and San Mateo is also in red.
Those maps are based on geography and vegetation type which is all well and good but if your geography is risky you can mitigate the risk. Earthquakes are another risk so you strap or bolt your house to the foundation and take care not to have lots of heavy stuff in our house that is unsecured. Fire is no different. See my comments in the SF thread.
