“…The study of spatio-temporal deformation changes in technogenically destabilized territories includes a number of geodetic, geological, geophysical, geotechnical methods or their combinations, which are presented in the works of Ukrainian [Mordvinov et al, 2018;Palamar & Syzova, 2015;Savchyn et al, 2019;Tretyak et al, 2015;Zakharova et al, 2020;Zayats et al, 2017] and foreign [Akgun et al, 2012;Beavan & Litchfield, 2012;Calcaterra et al, 2012;Casagli et al, 2017;Jaboyedoff et al, 2012;Sabuncu & Ozener, 2014] scientists. The choice of study method directly depends on the research goal and object, as well as available devices and instruments for conducting experiments to obtain input data.…”

“…To conduct continuous monitoring of a certain area with inclinometers, a network of several instruments is required, being installed at special inclination stations, where electricity, access to the Internet and connection to a computer with specialized software should be provided [Zayats et al, 2017]. For monitoring purposes, inclinometric observations are combined with GNSS, which allows data correlation [Mordvinov et al, 2018;Calcaterra et al, 2012;Savchyn et al, 2019].…”

The aim of the work is to analyze and evaluate current methods for studying Earth’s surface subsidence-dip deformation processes of technogenically impacted areas and to classify these methods. The analysis of existed methods for studying the spatio-temporal changes in the Earth’s surface consists in their critical assessment based on studied literary sources and highlighting advantages and disadvantages of the geodetic methods for studying the deformation processes of hazardous territories (with landslides and failures). Applying the classification method, a scheme of geodetic methods used in the Earth’s surface monitoring of technogenically loaded areas was developed. The analysis and evaluation of actual geodetic methods for studying the quantitative parameters of subsidence-dip deformation processes has been carried out. Literary sources written by Ukrainian and foreign scientists are processed. The advantages and disadvantages of the studied methods are presented. The classification of geodetic methods for studying and monitoring Earth’s surface deformations has been developed. The obtained results can serve as a theoretical basis that allows for further improvement of the technology for studying subsidence-dip deformation processes of technogenically impacted territories in order to predict technogenic disasters, improve the environmental situation and ensure life safety. The presented classification structures the current geodetic methods of studying the quantitative parameters of the spatio-temporal changes of the Earth’s surface.

“…Karst phenomena violated the integrity of functioning structures, buildings, and utilities. The deposit development caused surface deflection [Savchyn et al, 2019;Zaiats et al, 2017], underground and surface karst formation. Its number and intensity, despite the mining cessation due to complicated hydrogeological conditions, increases over time [Chepurna, Samborska, 2017].…”

“…The landslides that occurred on the territory testify that the regulations for the potash salts extraction were not executed and the environmental foundations of mine conservation after their closure were neglected. This can lead to landslides in other parts of mines, where residential buildings, highways, hydro and power supply facilities are located [Savchyn et al, 2019;Zaiats et al, 2017]. This indicates dangerous technogenic activity in the region that impend the population and infrastructure.…”

The study analyzes the coordinate time series of five permanent International GNSS Service (IGS) stations located in New Zealand. It also considers their annual movement from 2009 to 2018. The raw data in the form of Receiver Independence Exchange (RINEX) files were taken from IGS database and processes by means of online processing service AUSPOS. Using coordinate time series, horizontal and vertical displacement rates were calculated covering the ten-year study period. According to the results, stations located at the North Island of New Zealand revealed an uplift of 31-32 mm/yr. At the same time, stations placed on the South Island showed the 21-22 mm/yr of positive vertical displacement. Regarding the horizontal displacements, their rates increase in North-South direction over the study region. In particular, two stations of North Island, located at the North-Western part, appeared in 24-25 mm/yr displacement, and one station at the Southern part of North Island showed the 35 mm/yr displacement rate. Stations, established at South Island, showed the horizontal displacement rates of 41-56 mm/yr. This research confirms the main contribution made to the field of crustal deformation studies, including the updated values of displacements along with their directions over the recent years. The results of this study can be used for further geodynamics investigations as well as for finding the most likely earthquake locations of the current study area.

“…Detection of such displacements and simultaneous confirmation between different pairs of GNSS stations will automate the search for local or regional geodynamic processes in the area, and further support in the study of the causes and assessment of the effects of similar spatial displacements. Such geodynamic processes could have a special impact on the results of GNSS monitoring of large electricity produced objects such as Hydroelectric Power Plants (HPP) [Tretyak, et al, 2014[Tretyak, et al, , 2017, Pumped Storage Power Stations (PSPS), Nuclear Power Plants (NPP), because sudden shifts can be interpreted as a dangerous situation, and also regions where active landslides occurred [Savchyn, et al, 2019].…”

Purpose. The purpose of this work is obtaining connections between the Baltic and European height systems based on the I class leveling between the Ukrainian and Polish control points of the base vertical networks and construction of the quasigeoid surface on the border area. Method. Full integration of the hight system of Ukraine into the European vertical reference system (EVRS) consists of two stages: modernization of the height network of Ukraine through its integration into the United European leveling network UELN; construction and use as a regional vertical date the model of high-precision quasigeoid, which will be consistent with the European geoid EGG2015. The analysis of methods of high-precision leveling in Ukraine and Poland, and also the analysis of methods of construction of quasigeoid models in these countries is performed. Results. For integrating the Ukrainian hight system into the UELN/EVRS2000 system, the Ukrainian side performed I class geometric leveling along two lines: Lviv - Shehyni - Przemysl and Kovel - Yagodyn - Chelm with total length of 196 km. The root mean square systematic error on both lines of leveling was s<0.01 mm/km. In turn, the mean square random error along the line Lviv - Shehyni - Przemysl is h=0.29 mm/km, and along the line Kovel - Yagodyn - Chelm is h=0.27 mm/km. For double control on the cross-border part, the Polish side performed high-precision leveling with a length of 33 km. The differences between the Ukrainian and Polish leveling in all sections are within the tolerance. The analysis of influence of geodynamic phenomena on control of high-precision leveling is carried out. GNSS-leveling was performed on all fundamental and ground benchmarks, as well as horizontal marks. These measurements were used to build a quasigeoid model for the border area of Ukraine. The MSE of the obtained quasigeoid model is about 2 cm, which corresponds to the accuracy of the input information. Scientific novelty and practical significance. The connection of the Ukrainian and European height systems will ensure Ukraine’s integration into the European economic system, participation in international research of global ecological and geodynamic processes, study of the Earth’s shape and gravitational field and mapping of Ukraine using navigational and remote-sensing satellite technologies. Calculation of a high-precision model of a quasigeoid on the Ukraine area in relation to the European height system, agreed with the European geoid EGG2015, will allow to obtain gravity-dependent heights using modern satellite technologies.
