"Roger will never accept my prediction since he does not understand my method so far."

Shan, does anybody besides yourself understand your method? I am under the impression that you refuse to divulge the details of your method. Forgive me if I am wrong on that. But, if I am right, then is not the statement that Roger does not understand your method kind of silly considering you are the only one who does understand it?

"Accidents normally took place in heavy traffic places rather than normal."

Which, I believe, is what Roger is trying to say. If your analogy is to draw a comparison to accidents with cars, of course more accidents happen where there are more cars. And Roger is saying that you will have more hits if your predictions are where there are more earthquakes. Heck, that's the whole basis of my little prediction scheme.

"As on observer I do my work sincerely."

I do not doubt your sincerity. But even the most sincere people can simply be wrong. (not that being wrong is intrinsically bad)

Just some observations on your way of thinking.
