Abstract
The University of Tadulako suffered significant damage after a tectonic earthquake with a magnitude of M 7.5 with a depth of 20 km that occurred on September 28, 2018. This incident happened because of its location very close to the Palu-Koro fault. The Ministry of Public Works and Public Housing was assigned to reconstruct damaged educational infrastructure there. Seismic hazard analysis was needed to prepare reconstruction development projects and mitigation efforts. Many studies are related to predicting ground motion due to seismic fault activity, one of which is the attenuation NGA West 2 models. This study aims to determine the relationship between fault effects and ground motion to estimate liquefaction-induced settlement at this project. The results show that the relationship between the fault effects and ground motion affects various PGA values. PGA value resulting from the CY14 model was used to estimate settlement because it considers the worst condition aspect, where the most significant settlement occurred at the drill point DP-05 of 10.234 cm. This settlement can happen because the liquefied soil layer at the drill point was quite deep compared to other drill points.
