“…There are various techniques to select pixels, either dominated by a single scatterer or using averaged (multi-looked) noise-reduced distributed scatterers. These measurement points form the base of the time series analysis of differential interferograms computed from either a single-reference or a multi-reference stack (for more details on the comparison of different techniques see, e.g., Crosetto et al, 2016;Osmanoglu et al, 2016;Manunta et al, 2019). To capture the high deformation rate of sequential depression and to maximize the coherence offered by the short spatial baselines and high revisit time of the Sentinel-1 mission, we used a multi-baseline approach of interferogram formation (usually called small baseline subset -SBAS; Berardino et al, 2002).…”

Abstract. Rock salt has remarkable mechanical properties and high economic importance; however, the strength of salt compared to other rocks makes it a rather vulnerable material. Human activities could lead to acceleration of the dissolution of soluble rock salt and collapse of subsurface caverns. Although sinkhole development can be considered a local geological disaster regarding the characteristic size of surface depressions, the deformations can result in catastrophic events. In this study we report the spatiotemporal evolution of surface deformation in the Solotvyno salt mine area in Ukraine based on Sentinel-1 interferometric synthetic aperture radar measurements. Although the mining operations were finished in 2010, several sinkholes have been opened up since then. Our results show that despite the enormous risk management efforts, the sinkholes continue to expand with a maximum line-of-sight deformation rate of 5 cm/yr. The deformation time series show a rather linear feature, and unfortunately no slowdown of the processes can be recognized based on the investigated 4.5-year-long data set. We utilized both ascending and descending satellite passes to discriminate the horizontal and vertical deformations, and our results revealed that vertical deformation is much more pronounced in the area. Analytical source modeling confirmed that the complex deformation pattern observed by Sentinel-1 radar interferometry has a direct connection to the former mining activity and is confined to the mining territory. With the 6 d repetition time of Sentinel-1 observations, the evolution of surface changes can be detected in quasi real time, which can facilitate disaster response and recovery.

“…These countries have studied the measurement methods, formation mechanism, and prediction methods of mining ground fractures. Ground collapse pits formed by underground mining are also the main forms of discontinuous deformation, which occur less in China, mainly in Poland [17][18][19][20][21][22], India [23][24][25][26], South Africa [27,28], UK [29,30], Japan [31], Spain [32], Korea [33], Turkey [34], etc. Taking Poland as an example, the monitoring, formation mechanism and prediction model of coal mining collapse pit are focused on.…”

The surface discontinuous deformation caused by coal mining has great damage to the ecological environment and threatens the safety of human lives. Focusing on the problem of discontinuous deformation (ground fissures and collapsed pits) in mining areas with a thick loess and thin bedrock, this paper uses a coal panel in southern Shanxi in China as research background, and uses field investigation, theoretical analysis and the particle flow code 2D (PFC2D) numerical simulation method to study the movement of overburden and discontinuous ground deformation of mining areas with a thick loess layer and a thin bedrock. The results show that with the continual advance of the working face, the failure of the overlying rock, the changing of force chain shape and the development of cracks under this geological and mining condition have their unique rules. This study analyzes the law of movement of overburden in coal seam mining, explains why discontinuous deformation of the surface occurs in case of a thick loess layer and thin bedrock, and provides reference for the prediction of fracture development under the same geological conditions and the application of the PFC2D in coal seam mining in different geological conditions.

“…However, the literature documenting detection of precursor phenomena through remote sensing is very limited. Many researchers (Intrieri et al, 2015;Gutiérrez et al, 2019;Malinowska et al, 2019), mention, that there is a need for an identification of precursory deformation prior to the catastrophic main sinkhole events. Baer et al (2018) suggest that the temporal relationships between subsidence and sinkhole collapse and particularly the factors controlling the duration of the precursory subsidence are still poorly understood.…”

“…Tshwane municipality also sources more than 40 million litters of drinking water per day (5 %-8 % of requirements) from the dolomite aquifers, (Dippenaar et al, 2019). Nof et al (2019) propose that sinkhole potential maps are mandatory for the planning and licensing of new infrastructure. The necessity for effective monitoring and installation of early warning systems is required to reduce the risk for people, infrastructure, and property.…”

Detection of sinkhole occurrence, experiences from South Africa

Sinkholes are alarming and dangerous events, they have a worldwide occurrence, and are imposing a potential risk to urban communities and the widely developed built environment. Losses due to catastrophic sinkhole collapse, foundation, pavement and structural repairs, occur more often, due to the increased pressure to develop even on sinkhole prone land, and the aging of existing water supply infrastructure in the majority of cities. Remote sensing earth observation methods have proved to be valuable tools during the last two decades in long-term sinkhole hazard assessment. Satellite air borne and ground earth observation methods have primarily facilitated the wide detection of continuous displacement on the earth's crust. National sinkholes catalogues are necessary for town planers decision makers, and government authorities. In many instances the ground collapse is the result of water ingress from old poorly maintained leaking pipelines, or extensive dewatering activities. In the current study a comprehensive review of the current literature is presented in order to show experiences from South Africa and present recent mapping using PSInSAR methodology in Centurion South Africa.
