The volcano-geology map is basis information, not only for hazard mitigation related to volcanic activity, but also for resource exploration as well as scientific purposes. Therefore, the accurate detection and observation of volcanic products and their genetics are necessary for volcano-geology mapping. The classical problem at Torrid Zone such as cloud, dense vegetation, heavy weathering, and erosion usually hamper the detection and observation of volcanic products and their structures. Moreover, the stratigraphic of volcanic products generally follows paleotopography which was buried by the products. Overcoming the problem, we exploited the applicability of remotely sensed data to provide the great assistance for field based observations at volcanic field in Indonesia. The Geomorphologic and Structural Features (GSF) of the Synthetic Aperture Radar (SAR) are the selected parameters to define the distribution of the volcanic products. We explained about the significant of SAR identification to detect and interpret volcano-geology parameters such as eruption centers, volcanic products, depositional mechanisms, and volcanic structures especially at complex of volcanoes. The fall and flowing mechanisms controlled the depositional process were also analyzed to obtain the genetic of volcanic products. For young volcanoes, the quantitative techniques based on SAR surface roughness and polarized signatures are effective to identify volcanic formations and their sources. However, for old volcanoes the visual analyses of GSF is superior to identify the volcanic units and structures. We selected two volcanic complexes at Mts. Guntur and Malabar in West Java (Indonesia) presenting the young and old volcanic field characteristics under Torrid Zone condition.[/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]This research was supported by IPTEKS research scheme from Kemenristekdikti Indonesia PALSAR data were provided by The Remote Sensing Technology Center (RESTEC) Japan.[/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/10.1063/1.4987093[/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]
