u.s. seismic zones
 

u.s. seismic zones
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

check out our whitepaper library.
the newer standards don't use the zones- see asce 7-05.
