Thanks for the scientific view. Very interesting and makes sense. I live in the seismic safety of Placer County now, but lived in Santa Clara County for 20 years. As dramatic as some of the CA stuff, I’ve always regarded the NW as generally more dangerous. I mean, Mt Lassen hasn’t popped off since 1915, so at least we don’t have earthquakes AND active volcanos down here!
Please don’t become complacent in placer county. You have the Foothills fault system cutting through it capable of a pretty good jolt (iirc mag 5 rang, but my memory fades) Lived in sacto for 24 years and earthquake studies for corps of engineer dams always had to factor then in. However beats Santa Clara by a mile.
