Merapi and its vicinity based on seismic tomographic imaging. The DOMERAPI seismic network was running from October 2013 to April 2015 consisting of 53 broad-band seismometers, covering Mt. Merapi and Mt. Merbabu, and some geological features such as Opak and Dengkeng faults. Earthquake hypocenter determination conducted in this study is an important step before seismic tomographic imaging. The earthquake events were identified and picked manually and carefully. The majority of earthquakes occured outside the DOMERAPI network. The ray paths of seismic waves from these earthquakes passed through the deep part of the study area around Merapi. The joint data of BMKG and DOMERAPI networks can minimize the azimuthal gap, which is often used to obtain an indication of the reliability of the epicentral solution. Our preliminary results show 279 events from October 2013 to mid August 2014. For future work, we will incorporate the BPPTKG (Center for Research and Technology Development of Geological Disaster) data catalogue in order to enrich seismic ray paths. The combined data catalogues will provide information as input for further advanced studies and volcano hazards mitigation.[/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][/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/10.1063/1.4947377[/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]
