I hear ya, this entire coastline and continent is heavily tectonic history laden, scientists have only scratched the surface..
We’re supposedly at a point where the hayward goes deep
North of us,, that would likely cause the most damage here locally imo, but you never know where a segment is gonna let go elsewhere closeby, the quake of ‘06 shook the ol’ town up pretty good,, and they’re finding faults all over these days.. they have better instruments to find them.. some things we may not want to know. :-} but what do I know, I would like to retire on the Big Island down the coast from volcanos.
I agree with your take on the primary dangers in your area, and your thoughts on the modern technology that helps find new faults.
You’re not the first person I’ve known to think the Big Island might be a good place to settle down.
It would seem to me that a volcanic range might itself be prone to shaking.
All in all, modern civilization has benefited from a fairly static surface area. We know in the past things weren’t always that way, and I suppose in the back of my mind I sometimes wonder if a new restructuring of the surface might take place at some point.
