“…Moreover, extended forested areas and snow coverage for long periods of the year represent a constraint in SAR measurement point detection and its uniform distribution in the alpine territories. In the literature [5,42,50,51], it is stated that the number, distribution, and density of SAR data impact the correct assessment of the local-scale kinematic behavior. A proper SAR data coverage analysis led to identifying areas or domains with a small number of measurement points and uneven distribution, poorly representative of a proper interpretation of local deformation.…”

Deep-seated gravitational slope deformations (DsGSDs) are slope-scale phenomena which are widespread in mountainous regions. Despite interacting with human infrastructures and settlements, only a few cases are monitored with ground-based systems. Remote sensing technologies have recently become a consolidated instrument for monitoring and studying such widespread and slow processes. This paper proposes a three-step novel methodology to analyze the morpho-structural domain of DsGSDs by exploiting the advanced Differential Synthetic Aperture Radar Interferometry (A-DInSAR) technique through (i) the analysis of A-DInSAR measurement point density and distribution defining a coverage threshold; (ii) the assessment of the actual ground deformation with respect to the orientation of phenomena based on slope, aspect, and C-index; and (iii) ground deformation mapping with previously ranked velocity interpolation. The methodology was tested on two differently oriented phenomena: the mainly north–south-oriented Croix de Fana and the mainly east–west-oriented Valtournenche DsGSD, located in the Aosta Valley Region, northern Italy. The results show a variation in the kinematic behavior between the morpho-structural domains, while also considering any other superimposed surficial deformations. This work provides the lines for the implementation of a rapid and low-cost tool based on the use of A-DInSAR measurements which are suitable for assessing the impact of any type of DsGSD on the anthropic facilities and infrastructures in mountainous areas.

“…The values of differential subsidence were categorized into 3 classes as shown in Figure 3c. (d) The water table drawdown was calculated from the difference between the water table level in 2011 and that in 2007; the data was obtained from the official CONAGUA website [43]. The magnitude of the drawdown was classified into 3 classes as shown in Figure 3d.…”

Determination of Susceptibility to the Generation of Discontinuities Related to Land Subsidence Using the Frequency Ratio Method in the City of Aguascalientes, Mexico

et al. 2023

Land subsidence in the Aguascalientes Valley, documented since the 1980s, has developed a large number of discontinuities that damage infrastructure. There is currently no methodology to accurately predict the site and time at which a discontinuity will occur, making it difficult to make decisions in urban planning or risk management. However, it is possible to determine the susceptibility of an area to the generation of fractures based on the factors associated with their formation. This study presents a zoning method based on the ground failure susceptibility index (GFSI) in the city of Aguascalientes, using the frequency ratio (FR) method and employing the depth of the basement, the subsidence rate, the subsidence gradient, and the groundwater level drawdown as variables. The zoning method included three categories of land subsidence susceptibility to fracturing, moderate, high, and very high, which were divided using the first (3.76) and second (4.24) quartiles of the GFSI. The zoning method was created with the discontinuities reported in 2010 and was validated with data from 2022. The results obtained show that 11.19% of the discontinuities developed between 2010 and 2022 were located in a zone of moderate susceptibility, 41.97% were located in a zone of high susceptibility, and 46.87% were located in a zone classified as having very high susceptibility.

“…More than 50 million data points with time series spanning from 2015 to December 2021 are included in the data set [30]. In 2022 the European Environment Agency launched the European Ground Motion Service (EGMS) 3 , which covers the majority of Europe. The pre-processing of the BBD data can be found in [30] and is briefly explained in our earlier work [21].…”

“…One consequence of this could be damage to buildings due to irregular or unforeseen ground subsidence. For climate-resilient urban planning, it therefore makes sense to identify risk areas and take countermeasures [3]. The analysis of previous ground movements in a region can help to estimate future behavior.…”

Thanks to the open publication in recent years, the general public can now view and evaluate ground motion data. However, the data offered in web portals are often only optimized for display, and there is no automatic detection of hotspots and their analysis. In this study, ground motion patterns are investigated using Persistent Scatterer Interferometry data from the Ground Motion Service Germany. We focus on the identification of regions with significant ground motion in cities using a Ground Motion Analyzer, time series analysis and external data. A case study in Frankfurt am Main shows significant subsidence in the city presumably due to groundwater extraction during the construction phase of various buildings. Another case study in Crumstadt in the northern Upper Rhine Graben reveals pronounced seasonal fluctuations, probably due to factors such as temperature and activity in a nearby underground storage facility. We show that it is important to include external data such as temperature, precipitation and gas storage levels in order to comprehensively analyze the causes of ground movements. Our results contribute to understanding and mitigating the effects of ground motion and highlight the need to analyze time-varying motion in addition to linear velocities.
