EQ,

Let's get to the heart of the matter. What pattern of tides do you think is going to be a precursor to earthquakes?

It is not clear to me whether you are looking for patterns in space, time, or something else.

And in order to actually code this scheme up in a way that works, you would need to use eigenvectors, Green's functions, and deal with tensor stress and the mechanisms of the earthquakes. Please couch your plan in a way that would work.

I continue to have the feeling that your vagueness is a cover for not being able to do what you propose, nor even knowing what you're proposing. Plotting one chart above another, like your web page, is not a powerful tool.
