 Of 1987, I was working in my office on the seventh floor of the Santa Clara County building. I noticed that my pendulum, I have just a carpenter's plumb bob on about a five-foot catgut standing for the ceiling. It was swaying about two inches, and everybody was leaving around dusk. And I said, look at that. It was doing that same thing back in 1979 when they had the six-and-a-half magnitude quake down in Brawley.
