The clouds and thick vegetation always became an obstacle for remote sensing sensor to reveal surface geology feature. Therefore, the benefit of satellite data for geology exploration as well as hazard mitigation might be less effective. Nowadays, remote sensing technology seems to be approaching a new era in the use of microwave region onboard space borne termed as Synthetic Aperture Radar (SAR) sensor. In contrast with optical sensor, the SAR satellite generates its own signal in microwave frequency and receives the back-scattering intensity from material at surface, the sensor works regardless time acquisition and clouds cover especially at low frequency. In this paper, we present our achievements in the use of SAR sensor especially at C and L-band frequencies for geological explorations. The effectiveness of fusion data to detect the alteration zones and fluid paths of geothermal system were discussed, respectively. The capability of PolarimetricSAR to detect rock type distribution at active volcanoes was also explained even though ash and smoke covered the summit. We present the significant results for: (1) mapping alteration zones; (2) quantifying geological structures; and (3) identifying rock type distribution. The ground check and published data are always used for validating our result.[/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]Geological exploration,Geological structures,Geothermal,Geothermal systems,L-band frequencies,Remote sensing sensors,Remote sensing technology,SAR[/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]Explorations,Geology,Geothermal,SAR[/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][/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]
