The Eastern Indonesian region is marked by a complex tectonic zone as a result of the collision of three main plates in the world. Those are the Eurasian plate, the Australian plate and the Pacific plate. In a more detailed scale, the Sulawesi Island previously was formed by effects of collision of the Southeast Sunda Block and the Sula Block. Furthermore, the collision also created the Palu-Koro fault, the Matano fault and the subduction beneath in North Sulawesi Island's arm.<p> <br /> <br /> <br /> <br /> <br /> <br /> <br /> The regional tectonic activity caused this area as an active tectonic zone in Indonesia. So that a case study and evaluation on earthquake hazard in this area are needed. For that purpose, we used the Probabilistic Seismic Hazard Analysis (PSHA) method to analyze data consisting of earthquake source, fault source, subduction source.<p> <br /> <br /> <br /> <br /> <br /> <br /> <br /> Based on the resulting map of seismic hazard, that was produced using the PSHA method, it is known that Palu has the highest value of PGA, then followed by Gorontalo and Manado. Values of PGA decrease southward along Sulawesi. The dominant effects of seismic hazard in the main cities in Sulawesi are found in Manado, Makassar, Kendari and Mamuju, which were caused by the earthquake source, and in Palu and Gorontalo, which were caused by the fault source.
