I hope Jim and family moves from California soon...as I see it, not to far in the future California will be floating off in the Pacific Ocean, they will have to make their own power grid, sewer systems, grow their own food, drill their own oil and build refineries for gasoline...
Then again, California could become like the ‘City of Atlantis’ and never been seen again...
We will never know will we?
The only “catastrophic” seismic event that could conceivably happen to California (besides run of the mill things breaking) would be the uplift or pinching shut of the golden gate and subsequent damming of the Sacramento/San Joaquin river complexes resulting in the flooding of the delta and valley. I would hope that the people running the show here would breach that well before it became a problem.
It’s not going to sink, or break off and float away...
