Abstract

As one of the largest cities in Indonesia, Bandung city consists of dense populations that geologically surrounded by earthquake hazards. Therefore, a study on Peak Ground Acceleration (PGA) of the bedrock to analyze seismic hazard is a necessity. This study used the latest updated seismic sources data to model seismic ground motion to a particular location. Furthermore, the Probability Seismic Hazard Analysis (PSHA) methods were applied using EZ-FRisk and OpenQuake software. As a result, PGA bedrock using EZ-FRisk software ranged between 0,48-0,62g, while OpenQuake showed 0,539-565g. These results validated using Indonesian Hazard Map 2017 using PGA on 2475 years return period, represented similar values about 0.50-0.60g. In order to provide spatial information, these results visualized using Geographic Information System (GIS) application. Furthermore, this study expected to give contributions to scientific information for development planning, especially for designing earthquake-resistant buildings.
