It's hard to say that I experienced this event; I was asleep in a hotel on the bay side of
San francisco, during a business trip with my friend and colleague, Tony Pringle.
He was more sensitive to the shaking and other effects in the small hours of the morning.
I slept through it peacefully, then got the news from Tony the next morning!
