The resolution of this technique is very good. It is able to detect e.g., fractures due to their decreased mechanical resistance if they are covered, but in a shallow depth with a reasonable sampling distance. An example will be demonstrated where fracture system of a slowly-moving landslide was characterized enabling also its delineation. In spite of that its maximal penetration is only about 0.5 m it may also give information from remarkable depths in case if fractures reach close to the surface indicating the borders of geological structures in larger depth. An example from India will be shown to present such results. All results have been verified by geoelectric measurements. PreP may also indicate any kind of hidden holes indirectly.}, year = {2024}, eissn = {1587-3773}, pages = {358-363}, orcid-numbers = {Gribovszki, Katalin Eszter/0000-0003-2577-0127} } @misc{MTMT:34570407, title = {Seismicity map of the Circum-Pannonian region (456–2020) (M>2)}, url = {https://m2.mtmt.hu/api/publication/34570407}, author = {Győri, Erzsébet and Czecze, Barbara and Timkó, Máté and Bondár, István and Czanik, Csenge and Czifra, Tibor and Fodor, Csilla and Gráczer, Zoltán and Gribovszki, Katalin Eszter and Gyarmati, Anett and Kalmár, Dániel and Marótiné Kiszely, Márta and Kovács, István János and Mónus, Péter and Süle, Bálint and Szanyi, Gyöngyvér and Tóth, László and Varga, Péter and Zsíros, Tibor and Wéber, Zoltán}, doi = {10.23928/foldt.kozl.2023.153.4.mapA}, unique-id = {34570407}, year = {2023}, pages = {297}, orcid-numbers = {Bondár, István/0000-0002-4892-1074; Fodor, Csilla/0000-0001-9134-4017; Gribovszki, Katalin Eszter/0000-0003-2577-0127; Kovács, István János/0000-0002-3488-3716; Wéber, Zoltán/0000-0002-0017-3505} } @book{MTMT:34542660, title = {Hungarian National Seismological Bulletin 2022}, url = {https://m2.mtmt.hu/api/publication/34542660}, author = {Czanik, Csenge and Czecze, Barbara and Czifra, Tibor and Fodor, Csilla and Gribovszki, Katalin Eszter and Gyarmati, Anett and Győri, Erzsébet and Kalmár, Dániel and Marótiné Kiszely, Márta and Kovács, István János and Timkó, Máté and Varga, Péter and Wéber, Zoltán}, editor = {Süle, Bálint}, publisher = {HU-REN FI Kövesligethy Radó Szeizmológiai Obszervatórium}, unique-id = {34542660}, year = {2023}, orcid-numbers = {Fodor, Csilla/0000-0001-9134-4017; Gribovszki, Katalin Eszter/0000-0003-2577-0127; Kovács, István János/0000-0002-3488-3716; Wéber, Zoltán/0000-0002-0017-3505} } @article{MTMT:34216089, title = {Földrengések Répcelak környékén – 2021. szeptember}, url = {https://m2.mtmt.hu/api/publication/34216089}, author = {Győri, Erzsébet and Gribovszki, Katalin Eszter and Kovács, István János and Wéber, Zoltán}, journal-iso = {EPICENTRUM}, journal = {EPICENTRUM - A KÖVESLIGETHY RADÓ SZEIZMOLÓGIAI OBSZERVATÓRIUM ÉVKÖNYVE}, volume = {2021}, unique-id = {34216089}, issn = {2939-6085}, year = {2023}, eissn = {2939-6077}, pages = {37-43}, orcid-numbers = {Gribovszki, Katalin Eszter/0000-0003-2577-0127; Kovács, István János/0000-0002-3488-3716; Wéber, Zoltán/0000-0002-0017-3505} } @inbook{MTMT:34103098, title = {UTÁNPÓTLÓDÁS ÉS A NAPI TALAJVÍZSZINTINGADOZÁS}, url = {https://m2.mtmt.hu/api/publication/34103098}, author = {Gribovszki, Zoltán and Gribovszki, Katalin Eszter}, booktitle = {Az Erdőmérnöki Kar Tudományos Kiadványa}, unique-id = {34103098}, year = {2023}, pages = {106-110}, orcid-numbers = {Gribovszki, Katalin Eszter/0000-0003-2577-0127} } @article{MTMT:34102866, title = {3D finite element analysis of seismic response of a slender stalagmite}, url = {https://m2.mtmt.hu/api/publication/34102866}, author = {Marcin, Jaworski and Gribovszki, Katalin Eszter and Zbigniew, Zembaty and Piotr, Bonkowski and Piotr, Bobra}, journal-iso = {BULL GEOL SOC GR}, journal = {BULLETIN OF THE GEOLOGICAL SOCIETY OF GREECE}, volume = {Spec.

This is augmented by a case study where the authors carried out various cluster analyses of the focal mechanism solutions (FMS) estimated from local and teleseismic measurements and then performed stress inversions using the resulting clusters. This algorithm does not call for the setting of hyper-parameters by the users, thus greatly reducing the level of subjectivity introduced by user choice; the time required to finish the clustering can also be decreased. There is, however, an optional hyper-parameter which can be used for outlier detection, i.e. identify the data points considered to be noise in the input dataset, increasing the performance of the stress estimations. For probing the efficiency of their algorithm, systematic series of tests were executed on synthetic FMS data featuring clusters of various characteristics. During these tests, CluStress has been compared to other established clustering methods, namely, hierarchical density-based clustering for applications with noise (HDBSCAN) and agglomerative hierarchical analysis. Quantitative metrics, mainly the characteristic curves produced using the so-called silhouette-coefficient indicate that CluStress generates the most robust clusters for the stress inversions on synthetic data. A similar conclusion could be drawn from the same test performed using real FMS data of the investigated study area. As for this latter case, the resulting stress tensors show good agreement with the earlier published results with the notable exception of traces of extension, identified in some parts of the region after FMS clustering.}, year = {2023}, pages = {IUGG23-4514}, orcid-numbers = {Gribovszki, Katalin Eszter/0000-0003-2577-0127} } @article{MTMT:34101728, title = {A FORGÓLÉZERES SZINTKITŰZŐK VIZSGÁLATÁRÓL}, url = {https://m2.mtmt.hu/api/publication/34101728}, author = {Orbán, Aladár and Kalmár, János and Gribovszki, Katalin Eszter}, journal-iso = {GEOMAT KÖZL}, journal = {GEOMATIKAI KÖZLEMÉNYEK / PUBLICATIONS IN GEOMATICS}, volume = {26}, unique-id = {34101728}, issn = {1419-6492}, year = {2023}, orcid-numbers = {Gribovszki, Katalin Eszter/0000-0003-2577-0127} } @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} } @article{MTMT:33532115, title = {Improving ERT Imaging of Small-Size 2D Targets Using Different Strategies}, url = {https://m2.mtmt.hu/api/publication/33532115}, author = {Szalai, Sándor and Baracza, Mátyás Krisztián and Kárpi, Marcell and Szűcs, Péter and Metwaly, M. and Turai, Endre and Facskó, Gábor István and Zubair, M. and Szarka, László Csaba and Gribovszki, Katalin Eszter}, doi = {10.1007/s00024-022-03204-8}, journal-iso = {PURE APPL GEOPHYS}, journal = {PURE AND APPLIED GEOPHYSICS}, volume = {180}, unique-id = {33532115}, issn = {0033-4553}, year = {2023}, eissn = {1420-9136}, pages = {157-185}, orcid-numbers = {Facskó, Gábor István/0000-0001-9502-2816; Gribovszki, Katalin Eszter/0000-0003-2577-0127} }
