“…The coastal areas of Indonesia are also susceptible to land subsidence, particularly in the most densely populated island of Java. Large cities in the northern coast of Java are experiencing land subsidence at different rates, Jakarta and Semarang-Demak (1.0 to > 10.0 cm/year) [8][9][10], Pekalongan (4.8 cm/year) [10], and Surabaya (2.0 cm/year) [11]. The high rate of land subsidence in the coastal area is primarily related to the aquifer-aquitard system compaction due to the abstraction of groundwater [2,[12][13][14], although other factor such as natural compaction could coexist [15,16].…”

This article is currently under review oin Journal of Geosciences, MDPI. Authors: Dwi Sarah, Lambok Hutasoit, Robert Delinom, Imam A. Sadisun, Taufiq Wirabuana -- Semarang-Demak and other cities along the coast of North Java are vulnerable to land subsidence. The presence of saline groundwater in the coastal region is thought to affect the high subsidence rate, in this case the compressibility of the aquitard layer. We aimed to analyze the effects of groundwater salinity on the compression characteristics of the Semarang-Demak clay using physical analysis. Methods included the determination of groundwater salinity, clay mineralogy and fabrics, and consolidation tests under various salinity conditions. The Semarang-Demak clay is dominated by smectite of high activity and saline clay exists at the depth of 10 to 35 m. Consolidation tests reveals that the increase of salinity increases the average consolidation rate and hydraulic conductivity up to 42% and 37.5%, respectively. Clay fabric analysis showed that the groundwater salinity modified the interconnectivity of pores by changing the fabric into parallel alignments, facilitating faster porewater dissipation, hence the clay is more readily compressed. These findings are useful for explaining the mechanism of the fast-subsiding coastal plains of North Java.

“…This shows an indication of excessive land use and groundwater exploitation in the North Jakarta area, which has an impact on rapid land subsidence [21]. Land subsidence that occurs also has an impact on the occurrence of floods and other water disruptions, this indicates that conditions in the northern region are often hit by tidal floods [22].…”

DKI Jakarta, the capital city of Indonesia, as the center of growth and development has a high population. The high population has an impact on land use change in an effort to fulfill housing which directly impacts the increase in building density or Normalized Diffrence Built-up Index (NDBI). The purpose of this research is to analyze the rate of land subsidence in DKI Jakarta and analyze the effect of building density on land subsidence. The impact of high growth rates creates the potential for natural and anthropogenic disasters. This research uses the Differential Inferometry Synthetic Aperarure Radar (DinSAR) method, in observing land subsidence with accuracy reaching cm units. The data used in this research is Sentinel 1A image with observation time in 2018, 2020, and 2023. The results showed that land subsidence in DKI Jakarta was dominated in the North Jakarta area, the highest land subsidence value reached -26.08 cm/year. The fastest land subsidence occurs in densely populated areas prone to flooding. The correlation results show that there is no relationship between the high level of building density and land subsidence.

The QPS-InSAR technique appears in 2011 in [49], and in 2013 the SBAS technique is used for the the radar data from ALOS-2 satellite mission for subsidence monitoring in Surabaya, Indonesia [54]. Same year, the ISBAS technique is used for monitoring mining subsidence in South Derbyshire, U.K [62].…”

Mining activities represent one of the main causes leading to subsidence in the natural and urban environment. Sustainable urban planning and detection of potential hazards in mining areas involve the use of adequate instruments such as the continuous monitoring of land subsidence. The complexity of urban environment demands the utilization of new methods for monitoring and quantifying the effects of the mining processes. In the last decades, considering the technological developments from the remote sensing domain, the Synthetic Aperture Radar Interferometry (InSAR) techniques offer the opportunity for early detection and continuous monitoring of subsidence in mining areas, including urban centers. Considering various parameters of mining subsidence monitoring, a review of several tens of studies realized in different mining sites, based on InSAR techniques, is presented. As mining subsidence in urban areas has a direct impact on the quality of life, the review is completed with demographic indicators assessment, followed by a study case on the dynamics of the population in an urban mining area from Romania, Ocnele Mari.
