Here we address the topic of lithospheric structure by a combined geochemical and magnetotelluric analysis, which has been carried out in the framework of the Pannon LitH2Oscope project. The main objective was to detect the resistivity distribution over the entire lithosphere by magnetotelluric measurements, considering the lithological resistivity properties and relate the results to the structure and evolution of the Pannonian Basin. The Pannon LitH 2 Oscope MT array was used to estimate the depth of the Lithosphere-Asthenosphere Boundary (LAB), considering the legacy MT data and compared to previous estimates for the region. Using the MT and geomagnetic response functions, major structural zones of the Pannonian basin, such as the Mid-Hungarian Shear Zone or fault systems like the Makó Trough and the Békés Basin, were also imaged. In addition, we used the apparent resistivity soundings to compare 1D resistivity models computed from geochemistry and obtained from field MT measurements. This comparison provided new constrains for the composition, fluid and melt content variations at the local lithosphere-asthenosphere boundary. The Pannon LitH 2 Oscope MT dataset and the results presented in this paper provide input for more complex 3D inversions and further investigations of the lithospheric structure in the Carpathian-Pannonian region.}, year = {2024}, eissn = {2213-5820}, orcid-numbers = {Rubóczki, Tibor/0009-0008-1937-2580; Liptai, Nóra/0000-0002-2464-2468; Porkoláb, Kristóf/0000-0001-7470-8296; Galsa, Attila/0000-0002-7198-4524; Molnár, Gábor/0000-0001-9309-3418; Kovács, István János/0000-0002-3488-3716} } @CONFERENCE{MTMT:34644912, title = {Constructing a source model of the geodynamo using deep learning}, url = {https://m2.mtmt.hu/api/publication/34644912}, author = {Kuslits, Lukács and Lemperger, István and Horváth, András and Czirok, Lili and Wesztergom, Viktor}, booktitle = {XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG) (Berlin 2023)}, doi = {10.57757/IUGG23-4545}, unique-id = {34644912}, year = {2023} } @misc{MTMT:34580008, title = {Magyarország szeizmotektonikai térképe}, url = {https://m2.mtmt.hu/api/publication/34580008}, author = {Koroknai, B and Békési, Eszter and Bondár, István and Czecze, Barbara and Győri, Erzsébet and Kovács, Gábor and Porkoláb, Kristóf and Tóth, T and Wesztergom, Viktor and Wéber, Zoltán and Wórum, G}, doi = {10.23928/foldt.kozl.2023.153.4.mapD}, unique-id = {34580008}, year = {2023}, pages = {353}, orcid-numbers = {Békési, Eszter/0000-0003-3561-1656; Bondár, István/0000-0002-4892-1074; Kovács, Gábor/0000-0001-6720-3126; Porkoláb, Kristóf/0000-0001-7470-8296; Wéber, Zoltán/0000-0002-0017-3505} } @misc{MTMT:34576741, title = {GNSS-based strain rate pattern of the Pannonian region}, url = {https://m2.mtmt.hu/api/publication/34576741}, author = {Porkoláb, Kristóf and Taco, Broerse and Kenyeres, Ambrus and Békési, Eszter and Tóth, Sándor and Magyar, Bálint and Wesztergom, Viktor}, doi = {10.23928/foldt.kozl.2023.153.4.mapC}, unique-id = {34576741}, year = {2023}, pages = {311}, orcid-numbers = {Porkoláb, Kristóf/0000-0001-7470-8296; Kenyeres, Ambrus/0000-0003-2714-6555; Békési, Eszter/0000-0003-3561-1656; Tóth, Sándor/0000-0001-8445-9027; Magyar, Bálint/0000-0002-2464-6805} } @misc{MTMT:34526451, title = {Application of PS and SBAS radar interferometry for large-scale investigation of surface motions in Hungary}, url = {https://m2.mtmt.hu/api/publication/34526451}, author = {Bozsó, István and Szűcs, Eszter and Szárnya, Csilla and Wesztergom, Viktor}, unique-id = {34526451}, abstract = {Satellite based synthetic aperture radar (SAR) interferometry (InSAR) has become a widely used tool for mapping and monitoring surface displacements alongside GNSS. The launch of the Sentinel-1 satellites, providing high-quality SAR images in C-band (5.405 GHz) at a very high temporal frequency (every 6 days until the end of 2021). The advancements both in computing capacity and processing algorithms enabled the determination of surface displacements on regional and even continental scale. C-band based InSAR processing has many limitations however, when applied in temperate regions. Seasonal change in soil moisture, vegetation foliage, surface coverage (snow cover) and agricultural activities (plowing, seeding, crop development) can all lead to loss of coherence and consequently loss of deformation information. These factors can render the determination of surface motions very difficult in areas where the velocity of these motions is low (< 1-2 mm / year). In this contribution the authors wish to present results of InSAR processing applied to an area (Hungary in Central Europe) where the mentioned limitations (temperate region, low expected displacement velocities) are present. Approximately 250 Sentinel-1 images, both ascending and descending direction, between 2016 and 2021 were processed covering the area of interest. The images were processed using the Gamma software package (https://www.gamma-rs.ch/software) with both Persistent Scatterer (PS) and Small Baseline (SBAS) InSAR processing methods. We present the results of the two processing strategies, discuss the advantages and shortcomings, and provide an outlook on future work, with recommendations on how to plan and execute such large-scale analysis.}, keywords = {Space geodesy; InSAR; PSInSAR; SBAS-InSAR}, year = {2023}, orcid-numbers = {Szűcs, Eszter/0000-0001-6781-4269; Szárnya, Csilla/0000-0002-8880-194X} } @article{MTMT:34502759, title = {HUNGARIAN CONTRIBUTION TO THE RESEARCH ON OBSERVATORY, INSTRUMENTS, SURVEYS AND ANALYSIS (2019-2022) - IAGA DIVISION V}, url = {https://m2.mtmt.hu/api/publication/34502759}, author = {Lemperger, István and Csontos, András Attila and Heilig, Balázs and Szabados, László and Kovács, Péter Gábor and Szendrői, Judit and Wesztergom, Viktor}, journal-iso = {GEOMAT KÖZL}, journal = {GEOMATIKAI KÖZLEMÉNYEK / PUBLICATIONS IN GEOMATICS}, volume = {25}, unique-id = {34502759}, issn = {1419-6492}, year = {2023}, pages = {81-86}, orcid-numbers = {Heilig, Balázs/0000-0002-7964-0048} } @book{MTMT:34494666, title = {Magyar Űrkutatási Fórum 2023 - Válogatott közlemények}, url = {https://m2.mtmt.hu/api/publication/34494666}, isbn = {9789637367335}, editor = {Bacsárdi, László and Barta, Veronika and Szárnya, Csilla and Wesztergom, Viktor}, publisher = {Hungarian Astronautical Society}, unique-id = {34494666}, year = {2023}, orcid-numbers = {Bacsárdi, László/0000-0002-7337-317X; Szárnya, Csilla/0000-0002-8880-194X} } @CONFERENCE{MTMT:34069125, title = {Integrated Geodynamic Stations in Central Europe}, url = {https://m2.mtmt.hu/api/publication/34069125}, author = {Kovács, István János and Szabó, Csaba and Szakács, Alexandru and Lange, Thomas Pieter and Kővágó, Ákos and Gelencsér, Orsolya and Gál, Ágnes and Berkesi, Márta and Liptai, Nóra and Patkó, Levente and Palcsu, László and Bozsó, István and Gergely, Szilveszter and Süle, Bálint and Novák, Attila and Wesztergom, Viktor}, booktitle = {Goldschmidt 2023 Conference: abstracts}, unique-id = {34069125}, year = {2023}, pages = {20764}, orcid-numbers = {Kovács, István János/0000-0002-3488-3716; Szabó, Csaba/0000-0002-1580-6344; Lange, Thomas Pieter/0000-0002-8709-9239; Gelencsér, Orsolya/0000-0001-8615-9298; Gál, Ágnes/0000-0001-5366-3340; Berkesi, Márta/0000-0003-4380-057X; Liptai, Nóra/0000-0002-2464-2468; Patkó, Levente/0000-0001-6007-3103; Gergely, Szilveszter/0000-0003-1945-526X} } @article{MTMT:34059446, title = {Hungarian Contribution in EM methods (2019-2022) - IAGA Division VI : Electromagnetic Induction in the Earth and Planetary Bodies}, url = {https://m2.mtmt.hu/api/publication/34059446}, author = {Szarka, László Csaba and Ádám, Antal and Novák, Attila and Rubóczki, Tibor and Lemperger, István and Prácser, Ernő and Szalai, Sándor and Wesztergom, Viktor and Kiss, János and László, Zilahi-Sebess and Károly, Rádi and Fancsik, Tamás and Turai, Endre and Szabó, Norbert Péter and Nádasi, Endre and Baracza, Mátyás Krisztián and Vass, Péter and Szűcs, Péter and Dobróka, Mihály}, journal-iso = {GEOMAT KÖZL}, journal = {GEOMATIKAI KÖZLEMÉNYEK / PUBLICATIONS IN GEOMATICS}, volume = {25}, unique-id = {34059446}, issn = {1419-6492}, abstract = {The purpose of the journal is to provide the home researchers and experts a forum to publish, mainly in Hungarian language, their new scientific results in the field of geosciences (geodesy, photogrammetry, geoinformatics, physical geodesy, geophysics, Earth magnetism, geodynamics, research of the inner structure of the Earth and the physics of its troposphere and solar-terrestrial environment) obtained from the analysis of spatial-temporal data using the methods of geomatics.}, year = {2023}, pages = {87-92}, orcid-numbers = {Kiss, János/0000-0001-8589-1364; Nádasi, Endre/0000-0001-5325-6657; Dobróka, Mihály/0000-0003-3956-2070} } @article{MTMT:34049353, title = {Monitoring Strategy of Geological Hazards Using Integrated Three-dimensional InSAR and GNSS Technologies with Case Study}, url = {https://m2.mtmt.hu/api/publication/34049353}, author = {Bányai, László and Bozsó, István and Szűcs, Eszter and Gribovszki, Katalin Eszter and Wesztergom, Viktor}, doi = {10.3311/PPci.20009}, journal-iso = {PERIOD POLYTECH CIV ENG}, journal = {PERIODICA POLYTECHNICA-CIVIL ENGINEERING}, volume = {67}, unique-id = {34049353}, issn = {0553-6626}, abstract = {Geodetic/geodynamic benchmarks, equipped with both ascending and descending radar corner reflectors, and a method for integrated InSAR and GNSS/GPS network observation were developed and applied as the continuation of the former geodetic monitoring at the Dunaszekcső landslide, Hungary. The attempts to apply InSAR technologies using archive and Sentinel-1 data practically failed on the most intensive landside areas (“Vár” and “Szent János” hills), where proper persistent or distributed scatterers were not found. Our concept solved this problem, where the Simple Look Complex (SLC) images are used to interpolate the movements between two GNSS network observations using the integrated benchmarks and the method of Kalman-filtering. Since the InSAR line-of-sight (LOS) changes are barely sensitive to the north movements, this information is essentially provided by GNSS measurement alone, moreover, the GNSS measurements are used to: a) identify the benchmarks, b) detect the unwrapping errors and missing cycles and c) provide the boundary values of Kalman-filtering.After the installation of benchmarks three GPS observations were carried out and 69 ascending and 61 descending Sentinel-1 A and B images were processed. The data processing properly indicated the general movement history, which fit the curves of former geodetic observations, as well. The dense data points of the East and Up (vertical) components made possible more detailed geomorphologic interpretations of the ongoing process between two GPS observations. During the investigated periods the deceleration of movements was experienced, however, the deceleration of the dormant state needs the continuation of the monitoring.}, year = {2023}, eissn = {1587-3773}, pages = {992-1000}, orcid-numbers = {Szűcs, Eszter/0000-0001-6781-4269; Gribovszki, Katalin Eszter/0000-0003-2577-0127} }
