Lovely response, much more than I'd hoped for. Thank you sir.

I suppose another issue that then arises, even if we did have decent prediction, is how to present and use predictive info. A "traffic light" system leading up to a countdown? How not to scare people, destroy economies with false positives and off-timing?

A strange conclusion from my study (for sound) is that where eathquakes are concerned the next best thing to none at all is regular earthquakes.
