Modeling the geoid and polar motion in geological tim

The main objective of our research is to: 1) conduct a correlation analysis of the relationship between geoid heights and topographic heights in the modern era using calculated moving correlation coefficients (MCC); 2) extrapolate the obtained correlation model to past geological epochs and determine the paleogeoid using known surface heights derived from paleoDEM continental reconstruction models (Scotese and Wright, 2018); 3) perform calculations of changes in "True Polar Wander" (TPW) based on the obtained paleogeoid height data sets resulting from the movement of lithospheric plates.

Earth crust of eastern segment of Ukrainian Carpathians in the regional profile RP-5 zone: structure, geodynamics, oil and gas bearing

The purpose of the work is to present widely to the scientific community and analyze in detail the structure and oil and gas bearing of the Bukovyna lithosphere (the eastern part of the Carpathian region of Ukraine) based on the unique data on the regional RWМ-CDP profile RP-5 and on the neighboring regional profiles with the involvement of other geological and geophysical data.

On the distribution of tangential mass forces in the Earth's lithosphere

The study aims to determine and interpret the distribution of the global tangential mass force (TMF) vector field by azimuthal orientation and intensity. Using cluster and correlation analysis, we compared the direction of the TMF vector field with the direction of movement of permanent GNSS stations and the direction of movement of the GSRM model continental velocities from the Global Strain Rate Map Project. Methodology. The author continues their study of additional planetary stresses in the lithosphere caused by distributed mass forces.

A study of the influence of water level fluctuations on the geodynamic situation in the natural and technical geosystem of the Dniester HPP and PSPP cascade

Purpose. Statistical information for the period from 2016 to 2021 was used to analyze seismic activity. Objective. The aim of the study is to identify the relationship between changes in water level and local seismic activity in the region. Using HPP and Psing filtering, the hypocenters of earthquakes within a radius of 30 km from the seismic station with the NDNU index were selected, and using geographic information technology tools, the hypocenters of earthquakes were compared with the geological structure of the region. Methodology.

Seismotectonics of the Oash and Transcarpathian deep faults junction zone (Ukrainian Transcarpathians)

The purpose of the work is to study the features of seismotectonics of the junction zone of the Oash and Transcarpathian faults in the Ukrainian Transcarpathians. The research methodology combines a complex analysis of geological-tectonic, seismological, geomorphological and geodetic data on the studied area. For the clarification of coordinates and depths of local earthquake foci we applied methods of their hypocenters specification, using a calculated seismological hodograph and kinematic corrections.

Impact assessment and tereyniv sutur to modern crustal movements in the Carpatho-Balkans of the GPS-measurements and geological-geophysical data

Velocities of displacements of permanent GPS stations, located in Carpathian and Balkans region are computed. As a result directions and velocities of regional and local geodynamic movements are obtained. The estimation of the influence tereynov and suture to the modern tectonic activitythe earth's crust in the region.

Construction of the geodynamic models of the seismic active regions of the earth (the Neftegorsk earthquake, Sakhalin island)

The constructed model for a deep structure of the lithospere under the Neftegorsk earthquake region shows that North Sakhalin consists of the North Sakhalin sedimentary basin, the Deryugin basin and the ophiolite complex located between them. The ophiolite complex composed of the the ultrabasic rocks, fixes the position of the ancient subduction zone which was active about 100-60 million years ago. On a surface the subduction zone manifests itself as deep faults running along Sakhalin.

Analysis of thermal-elastic geomechanical processes on the base of complex deformational monitoring data

The thesis applies for the original geodynamical investigations of the Transcarpathians territory. New laser-digital techniques of tension and weather-temperature observations on the base of author’s implementations were used. Such techniques  allow to observe and study sub-low geological processes and movements before, during and after earthquakes, create a of tension and weather-temperature data base, make complex analyses and processing of geophysical information.
