RE: seismic intensity values
If I remember right it is a Mercalli style scale and is not used directly in design.
Have you tried Google?

Found that EQ measurement in "balls" is the Russian Medvedev scale, abbreviated MSK.
Did a search for:

And there are many, many, many seemingly useful results. Good luck!
