Waited 20 years to see if the house I designed and built was earthquake proof. Rode it out fine. The interesting sight was huge flashes to the east and west horizon during the whole thing. Thought it was lightning but turned out to be transformers and sub stations putting on a light show.
One of the men I talked to at church In Petaluma mentioned the “light show”
Interesting....glad your home withstood the quake as you hoped.....what did the flashes look like?
