“…Similar local land-surface subsidence with a maximum line-of-sight deformation rate of 5 cm/yr associated with sinkhole development in a salt exploitation area was also detected by InSAR methodology at Solotvyno in Ukraine, close to the Romanian border, as reported by Sz űcs et al, 2021 [48].…”

Ground and infrastructure stability are important for our technologically based civilization. Infrastructure projects take into consideration the risk posed by ground displacement (e.g., seismicity, geological conditions and geomorphology). To address this risk, earth scientists and civil engineers employ a range of measurement technologies, such as optical/laser leveling, GNSS and, lately, SAR interferometry. Currently there is a rich source of measurement information provided in various formats that covers most of the industrialized world. Integration of this information becomes an issue that will only increase in importance in the future. This work describes a practical approach to address and validate integrated stability measurements through the development of a platform that could be easily used by a variety of groups, from geoscientists to civil engineers and also private citizens with no training in this field. The platform enables quick cross-validation between different data sources, easy detection of critical areas at all scales (from large-scale individual buildings to small-scale tectonics) and can be linked to end-users from various monitoring fields and countries for automated notifications. This work is closing the gap between the specialized monitoring work and the general public, delivering the full value of technology for societal benefits in a free and open manner. The platform is calibrated and validated by an application of SAR interferometry data to specific situations in the general area of the Romanian Carpathians and their foreland. The results demonstrate an interplay between anthropogenically induced changes and high-amplitude active tectono–sedimentary processes creating rapid regional and local topographic variations.

“…The subsidence often remains hidden for a longer period of time, and it is perceived only by building damages [4] or rapidly developing devastating surface distortions such as sinkholes [5]. Salt mines, which have hundreds of years of mining history, are in the focus of mining subsidence monitoring [6] due to their intense distortions and the potential to release salted water as pollution during the flooding of their caverns [7]. Therefore, the potential risk emerged by salt mine subsidence and collapses [8] is wellknown across Europe [9][10][11].…”

“…Waldir et al used integrated SAR analysis techniques to map surface deformation processes in an open pit iron mine in Brazil and concluded that the space-borne SAR data used together with field monitoring is an effective way of surface deformation monitoring [15]. Sz űcs et al [7] demonstrated the effectiveness of the use of an interferometric synthetic aperture radar (InSAR) for surface deformation and subsidence monitoring for the period between 2014 and 2018, using Sentinel-1 data for the Solotvyno area. They concluded that the evolution of the surface changes due to mining activities can be detected.…”

The historical Ukrainian rock-salt mining town of Solotvyno and its environmentally related problems are well-known. A complex monitoring system is needed to evaluate the current situation in order to revitalize the investigated area. In addition to other risks, surface deformation due to undermining is one of the major risks endangering building infrastructure in the inhabited area of the town. These processes are well-known in the area, and damages caused by the surface movement are often recognized. Measurement of the process’s intensity and identification of the impacted area are crucial for any revitalization work. Information on these processes is the most important element of the hazard management and spatial-developmental planning of the town. This study aimed to characterize the long-term surface deformation processes and to identify the spatial and temporal trends and changes of these processes to assist spatial planning. The first step was to understand the surface deformation history from 1992. An InSAR-based assessment of the surface displacement of the undermined Solotvyno area was performed using data from three satellites, namely the ERS, Envisat, and the Sentinel-1, covering the time period between 1992 and 2021. The derived quantitative analysis indicated an intensive surface displacement and subsidence over the mining area. However, these displacements have not been even in the last 30 years of the investigation. The identification of the stabilized areas and recently started movements indicated the dislocation of the processes, which requires adequate actions for geohazard management and strategic planning. The demonstrated technology (InSAR) has the potential to set up an appropriate alarm system and provides an automated mechanism for continuous risk detection. A complex systems development is able to significantly reduce the geohazards over the unstable built-up zones.

“…In recent years, radar has become the primary tool for identifying and understanding the evolution of sinkhole-caused surface deformation (Paine et al, 2012;Conway and Cook, 2013;Nof et al, 2013;Rucker et al, 2013;Caló et al, 2017;Szűcs et al, 2021). While prediction of the next sinkhole to form is extremely difficult even with many predictor variables (Orhan et al, 2020), there are recent signs that the next generations of synthetic aperture radar (Baer et al, 2018;Emil et al, 2021) and X-ray diffraction (Ghrefat et al, 2021) may offer advances over earlier radar technologies for early warning of sinkhole formation.…”

Sinkholes (or dolines) are an often-overlooked environmental hazard. The processes that lead to their formation are slow and insidious, which encourage a lack of awareness or concern for the potential danger, until the sudden, climactic formation leads to unexpected property damage and possibly human casualties. This research identifies the risk to residential properties to the sinkhole hazard, using Louisiana, United States as a case study. Risk is defined as the product of the hazard intensity and the loss to structure and contents within the building resulting from the hazard-related disaster. Results suggest that risk is highly scale-dependent. Although the risk due to sinkholes is small on a per capita basis statewide, especially when compared to the per capita risk of other natural hazards, the property risk for census tracts or census blocks partially or completely overlying a salt dome is substantial. At finer scales, Terrebonne Parish, in coastal southeastern Louisiana, has the greatest concentration of salt domes, while Madison Parish, which is east of Monroe, has the highest percentage of area at risk for sinkhole formation, and St. Mary Parish—immediately west of Terrebonne—has the greatest risk of property loss. An Acadia Parish census tract has the maximum annual property losses in 2050 projected at $40,047 (2010$), and the highest projected annual per building ($43) and per capita ($18) property loss are in the same St. Mary Parish census tract. At the census block level, maximum annual property loss ($7,040) is projected for a census block within Cameron Parish, with maximum annual per building loss ($85 within West Baton Rouge Parish), and maximum per capita annual property loss ($120 within Plaquemines Parish). The method presented in this paper is developed generally, allowing application for risk assessment in other locations. The results generated by the methodology are important to local, state, and national emergency management efforts. Further, the general public of Louisiana, and other areas where the developed method is applied, may benefit by considering sinkhole risk when purchasing, remodeling, and insuring a property, including as a basis of comparison to the risk from other types of hazard.
