Do the U.S. still get their seismic data by the zone class? seismic zone 1,2,3,4, etc...
if so, how does one obtain the Sa values etc.... for the specific area.
Thanks in advance

(seismic hazard analysis may help)
essentially, you need Ss and S1 as well as the seismic site class to determine Fa and Fv. these together get you to Sds and Sd1.
