Seismic attenuation analysis of this subduction earthquake and probabilistic seismic hazard analysis (PSHA) post-Aceh earthquake as well as its associated geotechnical engineering issues for city of Banda Aceh is presented. It is indicated from seismic attenuation analysis that peak ground acceleration (PGA) at bedrock is estimated to be approximately a 400 years return period event as resulted from preliminary PHSA. Both subduction and Sumatra Fault Zones are considered in the PSHA. The analysis is conducted to provide recommendation on seismic peak ground acceleration criteria for rehabilitation and reconstruction of buildings and infrastructures of the city. Some geotechnical earthquake engineering issues observed from a reconnaissance survey conducted several weeks after the event and potential future geotechnical issues are addressed. Finally some input to potential future earthquake disaster mitigation strategies is provided.[/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]Ground motion analysis,Ground motions,Peak ground acceleration,Probabilistic seismic hazard analysis,Reconnaissance surveys,Seismic hazards,Subduction earthquakes,Sumatra fault zone[/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]Aceh earthquake,Geotechnical engineering,Ground motion,Probability seismic hazard,Reconnaissance Survey,Sumatra Fault Zone[/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][/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]
