“…It was observed that there were eight faults around Kunming, which controlled the formation and development of the basin. As many studies have indicated, the spatial distribution and shape of subsidence might be related with the faults [19,20,21]. In this study, Guandu subsiding region presented in the shape of a narrow funnel and extended in an approximate south-north direction, which followed the general trends of the surrounding F 149 and F 150 faults.…”

“…In this field, current research is focused on three aspects. The first aspect is applying the multi-sensor InSAR to derive the long-term ground deformation, such as in Tehran (Iran) [19], Xi’an (China) [20], Baja California (Mexico) [21], Urayasu (Japan) [22], the Italian Peninsula [23], Istanbul (Turkey) [24], and Semarang (Indonesia) [25]. The second aspect is resolving two- or three-dimensional ground motion through the multi-sensor SAR images merging technique, which has been used in an urban subsiding area [26], mining subsiding area [27], and co-seismic deformation area [28].…”

Large-scale urbanization has brought about severe ground subsidence in Kunming (China), threatening the stability of urban infrastructure. Mapping of the spatiotemporal variations of ground deformation is urgently needed, along with summarization of the causes of the subsidence over Kunming with the purpose of disaster prevention and mitigation. In this study, for the first time, a multi-temporal interferometric synthetic aperture radar (InSAR) technique with L-band Advanced Land Observation Satellite (ALOS-1) and X-band Constellation of Small Satellites for Mediterranean basin Observation (COSMO-SkyMed) data was applied to Kunming to derive the time series deformation from 2007 to 2016. The annual deformation velocity revealed two severe subsiding regions in Kunming, with a maximum subsidence of 35 mm/y. The comparison of the deformation between InSAR and leveling showed root-mean-square error (RMSE) values of about 4.5 mm for the L-band and 3.7 mm for the X-band, indicating that our results were reliable. We also found that the L-band illustrated a larger amount of subsidence than the X-band in the tested regions. This difference was mainly caused by the different synthetic aperture radar (SAR)-acquired times and imaging geometries between the L- and X-band SAR images. The vertical time series deformation over two severe subsiding regions presented an approximate linear variation with time, where the cumulative subsidence reached 209 mm during the period of 2007–2016. In view of relevant analyses, we found that the subsidence in Kunming was the result of soft soil consolidation, building load, and groundwater extraction. Our results may provide scientific evidence regarding the sound management of urban construction to mitigate potential damage to infrastructure and the environment.

“…The main geohazards include surface sinking, landslides, collapse of unstable rock masses, debris flows, and land subsidence. The human casualties and property damage caused by these geo-hazards necessitates urban subsidence monitoring to preserve the safety and integrity of infrastructure, and to responsibly manage urban planning [6]. At least 29 geo-hazards associated with surface sinking have been recorded in Wuhan from 1977 to 2014 [7].…”

Ground Deformation of Wuhan, China, Revealed by Multi-Temporal InSAR Analysis

et al. 2020

Wuhan, the largest city in central China, has experienced rapid urban development leading to land subsidence as well as environmental concerns in recent years. Although a few studies have analyzed the land subsidence of Wuhan based on ALOS-1, Envisat, and Sentinel-1 datasets, the research on long-term land subsidence is still lacking. In this study, we employed multi-temporal InSAR to investigate and reveal the spatiotemporal evolution of land subsidence over Wuhan with ALOS-1, Envisat, and Sentinel-1 images from 2007–2010, 2008–2010, 2015–2019, respectively. The results detected by InSAR were cross-validated by two independent SAR datasets, and leveling observations were applied to the calibration of InSAR-derived measurements. The correlation coefficient between the leveling and InSAR has reached 0.89. The study detected six main land subsidence zones during the monitoring period, with the maximum land subsidence velocity of −46 mm/a during the 2015–2019 analysis. Both the magnitude and the extent of the land subsidence have reduced since 2017. The causes of land subsidence are discussed in terms of urban construction, Yangtze river water level changes, and subsurface water level changes. Our results provide insight for understanding the causes of land subsidence in Wuhan and serve as reference for city management for reducing the land subsidence in Wuhan and mitigating the potential hazards.

“…If at some point the underground water level decrease becomes severe enough to cause stresses that exceed the preconsolidation stresses, a rearrangement of the granural material of the aquitards could occur. Then, the area will start experiencing inelastic deformation (e.g., [54][55][56][57][58]). In this case, the results would be irreversible or only partially reversible, even in the case of an aquifer recharge [59].…”

InSAR Campaign Reveals Ongoing Displacement Trends at High Impact Sites of Thessaloniki and Chalkidiki, Greece

et al. 2020

We studied the broader area of Thessaloniki in northern Greece and Chalkidiki and performed an InSAR campaign to study the surface deformation phenomena that have been known to exist for at least two decades. Sentinel-1 data (2015–2019) together with drill measurements were exploited to focus on specific sites of interest. Our results indicate an ongoing displacement field. At the region of Kalochori and Sindos—where intense subsidence in the 1990s was previously found to have had a natural surface rebound in the 2000s—a new period of subsidence, caused by the enlivenment of the groundwater overexploitation, was reported. The uplifting trend of Oreokastro is still active and subsidence in Anthemountas graben is ongoing; special focus was set on the Makedonia Airport, where significant displacement is occurring. The study also reveals a new area at Nea Moudania, that was not known previously to deform; another case corresponding to anthropogenic-induced surface displacement. Thessaloniki is surrounded by different persistent displacement phenomena, whose main driving mechanisms are anthropogenic. The sensitivity of the surface displacements to the water trends is highlighted in parts of the study area. Results highlight the plan of a water resources management as a high priority for the area.
