Abstract This research was conducted to determine and mapping the value of the PGA in Indonesian territory using two empirical models of attenuation equations from the transition of the second generation to the third generation. The research was conducted by applying the Frisenda’s and Luzi’s. The calculation is based on a catalog of earthquakes that occurred from 1 January 1970 - 31 December 2020 with a variable earthquake magnitude ≥ 5 SR and hypocentre depth ≤ 60 km (destructive earthquake). The calculation results in the maximum value of PGA respectively 0.6613 g for Frisenda, and 12.257 g in the Luzi. The maximum PGA value in Luzi model is the effects of the Andaman Islands earthquake on December 26 th , 2004, with a magnitude of 9,1 SR, and the maximum PGA value in the Frisenda model is the effects of the Flying Fish Cove, Christmas Island earthquake on June 13 th , 2013, with the magnitude 6.7 SR. In general, these two maps show different or even opposite patterns.
