Recently, in 2010, the Indonesian seismic hazard map was revised by our Indonesian Team from the 2002 map to a new hazard map. The revised map has adopted the most recent data and current state of knowledge in probabilistic and deterministic seismic hazard assessment methodologies, and through the use of the most recent ground motion predictive equations. So-called risk-targeted ground motions (RTGM) have also been developed. The risk-targeted ground motions for Indonesia are calculated as spectral response accelerations that result in 1% probability of building collapse in 50 years through a similar methodology as conducted by Luco et al. (2007). The authors do so by adopting generic fragility curves with alogarithmic standard deviation, β, value considered to be representative of Indonesian buildings. The risk-targeted ground motions mapped for the whole of Indonesia have been developed for short and 1.0 second spectral periods. These maps have become the risk-targeted maximum considered earthquake (MCER) maps in the new SNI 1726-2012.[/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]Building collapse,Fragility curves,Maximum considered earthquakes,Predictive equations,Seismic hazard assessment,Seismic hazard maps,Spectral response,Standard deviation[/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][/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]
