This is a semi dynamic datum in natural, which the reference epoch define at 2012.0 and the coordinates change due to plate motion and earthquake was accommodate using a deformation model. One of the components of deformation model is co-seismic deformation due to earthquake. In this study we estimate the co-seismic deformation model based on GPS time series data and earthquake geometry parameter. We used 4 major earthquakes with the magnitude > 8 Mw that occurred in the Indonesia region since 2004. Our result shows the rmse of residual co-seismic deformation from both method (GPS and earthquake modeling) in the East and North components is 4.10 mm and 5.26 mm for Sumatra Andaman 2004 EQ, 46.68 mm and 178.92 mm for Sumatra Utara 2005 EQ, 140.42 mm and 171.00 mm for Sumatra Selatan 2007 EQ, and 14.29 mm and 9.73 mm for Wharton Basin 2012 EQ. The preliminary model should be improved by including several earthquakes to get best co-seismic deformation model to support IGRS2013.[/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]Coseismic,Deformation model,SRGI2013[/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]This research is supported by Graduate Research in Earthquakes and Active Tectonics Program ITB and Geospatial Information Agency of Indonesia.
