Abstract

This study is performed to develop spectral hazard map for Indonesia with a Return Period of 2500 years earthquake. It will be proposed for revision of the Indonesian hazard map in SNI-03-1726-2002 as response to the meeting organized by the Department of Public Works on 27- October-2008 in Jakarta. The meeting has decided to revise the Indonesia hazard map by referring to IBC-2006 where spectral acceleration values at Peak Ground Acceleration/PGA, 0.2 and 1.0 second with a return period of 2500 year will be applied for general buildings. The spectral hazard map was analyzed using total probability method and three dimensional (3-D) source models with recent seismotectonic parameters. Four source models were used in this analysis, namely: shallow background, deep background, fault, and subduction source models. Generally, the results of analysis show the values of PGA with a return period of 2500 years relatively higher 1.2-3.0 times than in SNI-03-1726-2002.

Abstract

The tectonic plate movement that limits the Indonesian territory causes frequent earthquakes because the plates have dynamic rocks properties with varying strengths. The collision of the plates causes fault zones, such as in Bengkulu, a region traversed by the Sumatran fault with a record of many earthquakes. The rapid growth and development of technology could support increased infrastructure development by considering earthquakes a major global hazard. Therefore, this study aimed to create a PGA hazard curve useful in improving infrastructure development in Bengkulu's big cities. Data were sourced from the Book of Indonesian Earthquake Hazard and Source 2017. The United States Geological States Probabilistic Seismic Hazard Analysis (USGS PSHA) software was modified regarding the Ground Motion Prediction Equation (GMPE) database. The GMPE used in this study are (1) BC Hydro (2012) updated for subduction source; (2) Campbel Bozorgnia (2014), Boore Atkinson (2014) and Chiou Young (2014) for shallow crustal source, and (3) Zhao et al. (2006) and Abrahamson et al. (2018) for intraslab, with 500, 1,000, 2,500, 5,000, and 10,000 years return periods. The results obtained using the new GMPE showed a change in the maximum acceleration. The Hazard Curve (HC) and PGA map showed that the Kepahiang and Lebong Districts have the highest PGA values of 1.8070 and 1.8433 g, respectively, for the 10,000 year return period. The lowest value was 0.297g recorded in Rejang Lebong for 500 year return period.

Abstract

Buildings throughout Indonesia are at risk of experiencing damaging earthquake events from multiple sources within shallow crustal and subduction zones. Seismic assessments per SNI 9273: 2024 require earthquake acceleration time series, but a public web-based platform that can facilitate this need was not yet available. Thereby, it became urgent to investigate the possibility of developing an automated engineering tool that can determine hazard-consistent ground motion set with good target-match accuracy for regions where multiple seismic source contribution is prevalent. The investigation was conducted through the development of a fully-automated ground motion selection and scaling platform specifically customized to facilitate the seismic evaluation and retrofit of existing buildings throughout Indonesia, limited to upper bound period range of 3 s. This platform has been officially launched for public access by the Indonesian Ministry of Public Works to enhance the efficiency and accuracy of seismic assessments with the broader goal of improving seismic safety. Completion and test case validation of the platform confirmed that such useful tool can be developed provided that the following key features are incorporated: (1) specifically-defined scope of application; (2) comprehensive data integration to consider multiple seismic source contribution; and (3) modified greedy selection algorithm to enhance target-match accuracy
