Much of the analog paper records from this time period are preserved in the Tbilisi archives because Georgia served as the regional data center. In the 1990s, due to the collapse of the Soviet Union and the political turmoil in the region, the analog networks and the communication between the newly formed national networks deteriorated. In Georgia, for the next 13 yr, the seismic network coverage was poor until the 2002 Tbilisi earthquake. Following this earthquake, the first permanent digital seismic station in Georgia was established in Tbilisi in 2003. The digital era progressively improved the ability to collect and archive data and today more than a hundred broadband seismic stations (including temporary arrays) are operating in the southern Caucasus. Until recently, the region lacked a coordinated effort to catalog all analog and digital era data collected by different countries into a single repository. As a result of collaboration between Lawrence Livermore National Laboratory, the Ilia State University, and the Republican Seismic Survey Center of Azerbaijan, a comprehensive earthquake catalog was compiled for the Caucasus and neighboring areas as part of a broader probabilistic seismic hazard assessment project. This project digitized Soviet-era paper bulletins, compiled a unified earthquake catalog from regional bulletins, developed 1D reference velocity model, and used it to relocate the events. The final catalog contains 16,963 events with magnitudes 3.7 and above, bringing together all the available data sets in the Caucasus region from 1900 to 2015, significantly improving locations, and generating the most complete earthquake catalog in the region, temporally and geographically.}, year = {2024}, eissn = {1938-2057}, pages = {1066-1081}, orcid-numbers = {Gök, R/0000-0002-8479-675X; Bondár, István/0000-0002-4892-1074; Nabelek, J/0000-0001-6433-207X; Yetirmishli, G/0000-0002-0542-2443; Sandvol, E/0000-0002-3082-9149; Kadirioğlu, FT/0000-0002-5238-331X; Chiang, A/0000-0001-8513-4363} } @article{MTMT:34336608, title = {Relocation of the Seismicity of the Caucasus Region}, url = {https://m2.mtmt.hu/api/publication/34336608}, author = {Bondár, István and Godoladze, T and Cowgill, E and Yetirmishli, G and Myers, SC. and Gunia, I and Buzaladze, A and Czecze, Barbara and Onur, T and Gök, R and Chiang, A}, doi = {10.1785/0120230155}, journal-iso = {B SEISMOL SOC AM}, journal = {BULLETIN OF THE SEISMOLOGICAL SOCIETY OF AMERICA}, volume = {114}, unique-id = {34336608}, issn = {0037-1106}, abstract = {Our objective is to improve the view of the seismicity in the Caucasus region using instrumental data between 1951 and 2019. To create a comprehensive catalog, we combine the bulletins of local agencies and the International Seismological Centre, and use an advanced single-event location algorithm, iLoc, to obtain better locations. We show that relocations with iLoc, using travel-time predictions from the 3D upper mantle velocity model, Regional Seismic Travel Time, improve the locations. Then, using the iLoc results as initial locations and the ground-truth events identified in the iLoc results as fix points, we apply Bayesloc, a multiple-event location algorithm, to simultaneously relocate the entire seismicity of the Caucasus region. We demonstrate that the simultaneous relocation of the seismicity with Bayesloc clarifies the location and geometry of major active structures accommodating ongoing convergence between the Arabian and Eurasian continents between the Black and Caspian Seas. Among our major findings is the confirmation of widespread seismicity in the mantle beneath the northern flank of the Greater Caucasus and central Caspian, resulting from north-dipping subduction of the Kura and South Caspian basins and the identification of a discrete band of crustal seismicity beneath the southern flank of the Greater Caucasus.}, year = {2024}, eissn = {1943-3573}, pages = {857-872}, orcid-numbers = {Bondár, István/0000-0002-4892-1074; Cowgill, E/0000-0001-6017-4748; Yetirmishli, G/0000-0002-0542-2443; Myers, SC./0000-0002-0315-5599; Gök, R/0000-0002-8479-675X; Chiang, A/0000-0001-8513-4363} } @misc{MTMT:34580147, title = {Magyarország szeizmotektonikai veszélyeztetettségi térképe}, url = {https://m2.mtmt.hu/api/publication/34580147}, author = {Kovács, Gábor and Koroknai, B and Győri, Erzsébet and Németh, Viktória and Balázs, László and Bondár, István and Wórum, G and Szabó, G and Kegyes-Brassai, Orsolya Katalin and Tóth, Tamás}, doi = {10.23928/foldt.kozl.2023.153.4.mapE}, unique-id = {34580147}, year = {2023}, pages = {355}, orcid-numbers = {Kovács, Gábor/0000-0001-6720-3126; Balázs, László/0000-0003-1544-5734; Bondár, István/0000-0002-4892-1074; Kegyes-Brassai, Orsolya Katalin/0000-0001-8944-2742} } @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: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} } @CONFERENCE{MTMT:34087926, title = {Infrasound signal discrimination using machine learning}, url = {https://m2.mtmt.hu/api/publication/34087926}, author = {Pásztor, Marcell Sebestyén and Bondár, István}, booktitle = {CTBTO Infrasound Technology Workshop 2022 (ITW2022)}, unique-id = {34087926}, year = {2023}, orcid-numbers = {Bondár, István/0000-0002-4892-1074} } @CONFERENCE{MTMT:34087142, title = {Seismicity and Tectonics of the Caucasus Region Revisited}, url = {https://m2.mtmt.hu/api/publication/34087142}, author = {Bondár, István and Godoladze, T and Cowgill, E and Yetirmishli, G and Myers, S and Onur, T and Gunia, I and Buzaladze, A and Gök, R and Chiang, A}, booktitle = {IUGG Berlin 2023}, doi = {10.57757/IUGG23-1649}, unique-id = {34087142}, year = {2023}, orcid-numbers = {Bondár, István/0000-0002-4892-1074} } @CONFERENCE{MTMT:34087140, title = {CEEIN: The Central and Eastern European Infrasound Network}, url = {https://m2.mtmt.hu/api/publication/34087140}, author = {Bondár, István and Šindelářová, T and Ghica, D and Mitterbauer, U and Liashchuk, A and Neagoe, C and Pásztor, Marcell Sebestyén and Baše, J and Chum, J and Ionescu, C and Czecze, Barbara and Le Pichon, A}, booktitle = {IUGG Berlin 2023}, doi = {10.57757/IUGG23-1624}, unique-id = {34087140}, year = {2023}, orcid-numbers = {Bondár, István/0000-0002-4892-1074} } @CONFERENCE{MTMT:34087133, title = {Machine learning approach for automatic infrasound signal classification}, url = {https://m2.mtmt.hu/api/publication/34087133}, author = {Pásztor, Marcell Sebestyén and Bondár, István}, booktitle = {IUGG Berlin 2023}, doi = {10.57757/IUGG23-2618}, unique-id = {34087133}, year = {2023}, orcid-numbers = {Bondár, István/0000-0002-4892-1074} }
