Seismicity analysis can be carried out using deterministic and probabilistic methods. One approach that can be done with the help of OpenQuake is the Scenario Seismic Hazard Analysis (SSHA) and Probabilistic Seismic Hazard Analysis (PSHA) methods. The question arises regarding the equivalence between the two methods in producing earthquake acceleration values. In this study, it was tested using a single earthquake source, namely the Lembang Fault. The observed area is in the Bandung Basin area, bounded by mountains on the north and south sides. The method compares the acceleration values (PGA/Peak Ground Acceleration) between PSHA return periods of 500, 1000, 2500, 5000 and 10000 years with SSHA. The results obtained are a value agreement between PSHA with a return period of 5000 years and SSHA. The resulting acceleration (PGA) near the Lembang Fault is 0.5-0.6g.
