Abstract (English): 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-In-SAR) data to identify comprehensive subsidence and uplift patterns across Java Island. 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. [ABSTRACT FROM AUTHOR]
Abstract (Croatian): Otok Java doživljava složene i nelinearne deformacije tla uzrokovane interakcijom prirodnih i antropogenih čimbenika. Dosadašnja istraživanja uglavnom su bila usmjerena na slijeganje tla u urbanim sredinama ostavljajući obrasce deformacija na razini cijeloga otoka nedovoljno istraženima. Ovo istraživanje rješava taj nedostatak korištenjem viševremenske interferometrije sintetičkoga radara s otvorom antene (engl. Multi-Temporal Interferometric Synthetic Aperture Radar, MT-InSAR), kojom se identificiraju opsežni obrasci slijeganja i izdizanja tla na čitavome otoku Java. Rezultati pokazuju prethodno nedovoljno istraženo slijeganje tla u Karawangu (-1795 mm), Cilacapu (-902 mm) i Madiunu (-742 mm), koje premašuje slijeganje u priobalnome području Jakarte. Važno je istaknuti da se najizraženije slijeganje na području Velike Jakarte odvija u unutrašnjosti, kod Bekasija i Cikaranga, čime se osporavaju tradicionalne pretpostavke o slijeganju u urbanim zonama te pruža šire razumijevanje regionalne geodinamike otoka Java. Integracijom analize žarišnih područja i MT-InSAR metodologije unapređuje se praćenje deformacija tla te se naglašava važnost kontinuiranoga monitoringa za učinkovito upravljanje zemljištem i planiranje infrastrukture, posebice u visokorizičnim područjima koja nisu dovoljno pokrivena mjerenjima, kao što su Karawang, Cilacap i Madiun. Dobiveni rezultati mogu se primijeniti u geološkim istraživanjima, urbanističkome planiranju te donošenju politika u svrhu ublažavanja geoloških opasnosti i osiguravanja održivoga razvoja.
