Don, I'm tempted to send you the book but not sure if you'd read it. Not only did I personally witness many eq warnings before the foreshock and mainshock of Loma Prieta, but so did countless people. I am so sorry that you don't "see a warning or an indication" of oncoming quakes. Perhaps if you study my book you can be a bit more in tune to Mother Nature. And yes, it may save your own life one day.
