| dc.description.abstract | The Cugenang Fault is a new identified fault that caused the Cianjur Earthquake that occurred in November 2022, but the existence of the fault still hasn’t been clearly understood in the context of regional geology. In this study, satellite-based data is used to identify the fault, specifically GGMPlus gravity data to obtain the bouguer anomaly through gravity data correction, including terrain correction that utilizes Fatiando a Terra to calculate prism layer based on topography. The anomaly will be separated into regional and residual using upward continuation, and Horizontal Gradient Magnitude (HGM) calculation to identify structure boundaries including the fault itself. To validate the gravity processing, EMAG Magnetic data is used to delineate Total Magnetic Intensity (TMI) in the research area. Although the Cugenang Fault is not clearly delineated, several struc-
tural indications appear in the residual and HGM results, suggesting possible subsurface features. These findings emphasize the potential of gravity data integration to enhance fault mapping in complex geological settings, and further investigation with land high-resolution gravity data is recommended. | en_US |
