Dear Pelelo,
most method used to calculate PGA (peak ground acceleration) are probabilistic and determinisitic.
for the first one, A Cornell (1968) is the most known in which you may use seismic zones, attenutation law and B-values. for this task, softwares like crisis or seisrisk III can help assassing PGA for different return periof and probabilities of exceedance (in most case, 10 % of exceedance for 50 years but nowadays new american shakemaps are based on 2% of exceedance).
But the most accurate method is to modelise your soil and seismic wave propagation in order to calculate ground acceleration taking into account you soil behaviour wich can not be the same as those used for attenuation laws calibration. If you can't you can produce shakemaps by Wald model, you can transmit a scnario (fault, epicenter, magnitude) and they will provide a map for your region: they are all the time procuding such maps :
Hope I was helpful
