Improvement in seismic hazard analysis and careful inclusion of recent seismic records were augmented. Seismic sources were modeled by background, fault, and subduction zones considering truncated exponential model, pure characteristic model or both. Several well-known attenuation functions were selected including the Next Generation Attenuation (NGA). Maps of Peak Ground Acceleration (PGA) and Spectral Response Acceleration (SRA) for 0.2 s (short periods) and 1.0-s period for 2% probability of exceedance in 50 years were developed using PSHA. Additional geotechnical and tsunami hazard assessment researchs for Banda Aceh city, the capital of Aceh Province were also submitted. The results of site response analysis and liquefaction study at several points were utilized to generate contours of acceleration, amplification factor, design response spectra, and potential of liquefaction for Banda Aceh. The tsunami hazard study was conducted using mathematical simulation and modeling leading to estimate the potential tsunami that may occur in the future which covers tsunami inundation, run-up, and developing tsunami zonation map. The output of geotechnical and tsunami hazard assessment was then overlayed on top of the land use city planning in a Geographical Information Systems (GIS) database and used as criteria for tsunami warning system, an input in developing land use management for Banda Aceh, and enriching the basic regulation for new infrastructures and local building codes. © Springer Science+Business Media B.V. 2011.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1007/978-94-007-0470-1_8[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
