The only partially reliabilty in EQ forecasting is to read the Lost Pets section of a local newspaper everyday and count the number of ads. When the number of ads dramatically increase, one may expect an EQ within 72 hrs. The more dramatic the increase in ads, the stronger the EQ will be.

This was all figured out by Jim Berkley (sp?). A Geologist with the Orange County geological office. He's retired now but I think he wrote a book or two on the subject.
