seismic classification

Hi,
I've found this specification related to seismic classification : Classe 1 , zone2 , AS PER RPC 200, i need to know it's meaning, :-( i didn't found anything on google

Since this is the engineering part of the fourum, I'm doubtful my answer will be a very good one. I could be underestimating the folks here. But, this looks like a question some civil engineer would be best to answer. Not to say there aren't any hanging out at edaboard, but .... maybe a different forum would have more experts in this matter:

I got these from a page at: http://cescientist.com/list-of-civil-engineering-forums/ I just posted some links in case the page dies.

Good luck
