Java Island experiences complex and nonlinear land deformation resulting from the interplay of natural and anthropogenic factors. Previous studies predominantly investigated urban subsidence, leaving island-wide patterns less understood. This research addresses that gap by utilizing Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) data to identify comprehensive subsidence and uplift patterns across Java Island. Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) data reveal previously underrepresented subsidence at Karawang (-1795 mm), Cilacap (-902 mm), and Madiun (-742 mm) to be higher than coastal Jakarta's subsidence. Notably, Greater Jakarta's most severe subsidence occurs inland at Bekasi and Cikarang, which challenges common assumptions for urban subsidence. This challenges traditional perspectives on urban subsidence, offering a broader understanding of Java's regional geodynamics. By integrating hotspot analysis and MT-InSAR, the study enhances land deformation monitoring and requires continuous monitoring to enable efficient land management and infrastructure planning, particularly in high-risk, poorly monitored areas such as Karawang, Cilacap, and Madiun. These findings can be applied by geologists, urban planners, and policymakers to mitigate geological hazards and ensure sustainable development.
