The data (from USA) is provided for YOU, I thought you were interested in this field and you had been doing research on this. It just to show you that you can do something and prove whether the theory you have believed is solid.
About 耿庆国's theory, YOU need find the data from 5 sources and show us how to CALCULATE the possibility if you say it was 79% in this region, or anyone else claimed there would be a earthquake with some sort of possibility. If you fails, you, as a non-expert in this field, have to trust most (or majority) of the professionals in this field, not the particular one.
That's all I want to say.
