Abstract
Mount Ungaran, a stratovolcano in Central Java, Indonesia, exhibits complex morphological and structural characteristics that remain relatively underexplored. Understanding its volcanostratigraphy and internal structure is crucial for reconstructing its eruptive history and assessing potential geological hazards. This study employs a high-resolution drone-based remote sensing approach integrated with petrological analysis to investigate the volcano^s morphological anatomy, structural framework, and volcanostratigraphic evolution. High-resolution aerial imagery drone were generated to analyze topographic variations, volcanic landforms, and structural features such as faults, fractures, and lava flow distributions. The remote sensing data were complemented by field observations and petrographic analysis of rock samples to characterize lithological variations and identify key eruptive phases. Structural analysis focused on fault patterns and deformation features to understand the volcano^s tectonic influences and potential instability zones. Preliminary results reveal distinct stratigraphic sequences that indicate multiple eruptive stages, with significant variations in lava composition and depositional environments. Fault structures and fractures suggest interplay between regional tectonics and volcanic activity, contributing to the formation of the current morphology. The integration of remote sensing and petrology provides a more comprehensive understanding of Mount Ungaran^s geological evolution, allowing for improved hazard assessment and risk mitigation strategies.
