In this study, the sensitivity level of earthquake input motion in bedrock correlated with intensity arias and amplification occurring at the surface. The selected location of the study is an earthquake-prone area with the last record of a major earthquake in 2006, i.e., Yogyakarta Special Region. There are 3 (three) study areas with different geological environments. The analysis is determined by these steps: (1) Probabilistic Seismic Hazard Analysis/PSHA (2) disaggregation (3) selection of motion input and (4) wave propagation analysis to obtain a graph of Arias intensity and amplification value. All of those are aided by EzFrisk and DeepSoil software. The results of this study, i.e., the higher natural frequency at the site, then the lesser amplification developed. The highest amplification takes place at BH-04 which has the smallest natural frequency. On the other hand, the lowest value occurred at BH-02 on the highest natural frequency. There is a tendency that the smaller delta on the effective time arias intensity, the more significant amplification be occurred, except for Loma Prieta ground motion.[/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]Arias intensities,Disaggregation,Earthquake input,Effective time,Geological environment,Ground motions,Probabilistic seismic hazard analysis,Propagation analysis[/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/10.1088/1742-6596/1280/2/022069[/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]
