Abstract

Because Indonesia is countries between three major plates—the Indo-Australian plate in the south, the Pacific plate in the northeast, and the Eurasian plate in the north—high-intensity earthquakes are common in this region. Indonesia has a high seismicity level both on land and at sea as a result of these three plates coming together. Bali is one of the provinces that is particularly susceptible to earthquakes. Seismic hazards can be used to plan buildings resistant to earthquakes and describe the effects of an earthquake at a location, which can help anticipate community preparedness and efforts to mitigate earthquake disasters. The probabilistic seismic hazard analysis (PSHA) method is used for seismic hazard data processing in this type of descriptive research, which entails obtaining data from the NEIC/USGS earthquake catalogue for the years 1900 through 2015. The earthquake parameters that cause the greatest ground motion serve as the foundation for PSHA. The PGA results got from the Megathrust seismic tremor source peril map for the long-term return time frame went from 0.10 g to 0.30 g and the long-term return time frame went from 0.12 g to 0.45 g. For the PGA results obtained on the source risk guide of the Benioff model for a return time of 500 years, specifically 0.10 g to 0.12 g and for a return time of 2500 years, a worth of 0.12 g to 0.25 g is acquired.
