All rights reserved.The shakemap were usually generated based on strong ground motion calculations on attenuation equations of the Ground Motion Prediction Equation (GMPE). However, the GMPE is a general equation which does not take into account the structural model of each layer of the subsurface. It considers only the structure of the surface layer known as Vs30 calculated as amplification in shakemap calculation. In this paper, the realistic calculation of shakemap for Pidie Jaya earthquake of 7 December 2016 with magnitude M6.5 is performed. Shakemap is generated from a number of synthetics seismogram calculations from source to site-based capital calculation summation Technique. Neo Deterministic Seismic Hazard Analysis (NDSHA) has included in the calculation of the synthetics seismograph. Before engaging the Vs30 effect, the realistic shakemap capable of producing effects of the angular distribution of a double-couple model in a realistic calculation. This could give an advantage of realistic shakemap while the GMPE based shakemap had not taken into account the double couple model. The realistic calculation of modal summation technique for shakemap can be further developed by involving local structural models in a more comprehensive manner.[/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]Attenuation equation,Deterministic seismic hazard analysis,General equations,Ground-motion prediction equations,Modal summation techniques,Strong ground motion,Structural modeling,Structural models[/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]We thank seismology research group from Trieste University who provided remote computation facilities. We also thank USGS for providing the GMPE-based shakemap data. This research financially was supported by research project PUU-PNBP Universitas Syiah Kuala 2018 entitle “Updating Aceh Province Seismic Hazard Maps with Probabilistic and Neo-Deterministic Approach and Application for Pidie Jaya Microzonation”. The urgent research should be completed in 3 years, unfortunately, the project terminated funding support for 2019. We hope the research funding will be continued in 2020 in order to provide precise seismic hazard map for earthquake disaster mitigation in Aceh Province.[/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/10.1088/1755-1315/318/1/012005[/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]
