摘要：
Sumbawa Island, West Nusa Tenggara Province, is one of the regions in Indonesia that has a relatively moderate to high seismic activity because the area is flanked by two earthquake sources. These two sources cause an area prone to earthquake hazards. This research aims to determine the seismic risk in Sumbawa Island based on seismicity and Peak Ground Acceleration (PGA) value. The results of Gutenberg-Richter parameters are a-value 7.43 and b-value 0.80 that indicated medium to high categories of seismicity. The PGA value of earthquake events is between 0.001g and 0.203g. The result of this analysis is shown within the probabilistic seismic hazard curve that indicates seismic risk level at Sumbawa Island.
