Jim Berklund of Orange County, Los Angeles, Ca is now a retired Geologist, who worked for Orange County. He is a very accurate earthquake predictor.
His system is simple, he counts the number of Lost Pets ads in the paper everyday. When he notes a dramatic increase in "Lost" ads, he looks at where the various animals were lost at, area wise. That tells him where an earthquake is about to occur and how strong the earthquake will be.
Item to note: all those critters (sea lions???) that took over Pier 39 in San Francisco, have suddenly got up and left to parts unknown. I'm glad I don't live in San Francisco or anywhere thereabouts, right now.....
