A Study of Lineament Density and Correlation Residual Gravity Anomalies to Identify Pacul Fault in Mount Pandan, East Java

Abstract This study analyzes the identified Pacul Fault using lineament density and residual gravity anomalies in Mount Pandan, East Java. The study utilizes DEMNAS data, geological data, and gravity satellites. The research process includes creating hill shades from DEM data, extracting lineaments using PCI Geomatica software, and interpolating data to create a lineament density map. Further analysis correlates lineament density and residual anomaly with the fault zone around the Pacul Fault. The results show that fault zones are located in areas with moderate to high lineament density and at anomaly contrast from residual anomaly. The complete Bouguer anomaly map indicates low anomalies likely representing fault planes. This study confirms a positive correlation between lineament density and contrast anomaly according to the pacul fault presence of Mount Pandan.
