The basic geoelectric model in the Pannonian Basin is a (linear) tectonic zone (“dike”) and a series of dikes. In the second part the main crustal and mantle conductivity anomalies observed in the Pannonian Basin (PB) are summarized: (a) deep conductive crustal fractures and their relation to the occurrence of the earthquakes, boundary of the megablock(s) etc., (b) middle crustal conductors as indicators of decrease in stress and seismic activity depending on thermal regime, (c) the conductive asthenosphere and its lateral change in the PB in connection with the heat flow and tectonics. The general relation between the depth of the conductive asthenosphere and the regional heat flow is also presented, (d) MT anisotropy of the resistivity distribution in the PB and its tectonic explanation based on Haas’s tectonic map (2001, Fig. 1). All these observations and conclusions are considered as results for further investigations. © 2016, Akadémiai Kiadó.}, keywords = {electric conductivity; Tectonics; Levees; earthquakes; geodynamics; Hydraulic structures; Heat Transfer; Electrical conductivity; Calluna vulgaris; Seismic activity; Conductivity anomalies; Conductive asthenosphere; Resistivity distributions; Geoelectric models; General relations; Crustal conductors}, year = {2017}, eissn = {2213-5820}, pages = {205-228} } @CONFERENCE{MTMT:3165265, title = {Effect of ionospheric current system geometry on local surface EM observation - a theoretical model}, url = {https://m2.mtmt.hu/api/publication/3165265}, author = {Lemperger, István and Wesztergom, Viktor and Michel, Menvielle and Szalai, Sándor and Kis, Árpád and Novák, Attila and Ahmed, Lethy and Bencze, Pál and Kuslits, Lukács}, booktitle = {AGU Chapman Conference}, unique-id = {3165265}, year = {2016} } @{MTMT:3163258, title = {Ionospheric related research and development at the Geodetic and Geophysical Insitute}, url = {https://m2.mtmt.hu/api/publication/3163258}, author = {Barta, Veronika and Nagy, Tamás György and Berényi, Kitti Alexandra and Gergely, Pieler and Kalmár, János and Kovács, Károly and Sátori, Gabriella and Kis, Árpád and Bencze, Pál}, booktitle = {H-SPACE 2016}, unique-id = {3163258}, year = {2016}, pages = {27-28}, orcid-numbers = {Berényi, Kitti Alexandra/0000-0002-8799-5850} } @CONFERENCE{MTMT:3160859, title = {Q-bursts as Tools to Detect Structures of Anisotropic Conductivities in the Earth's Crust}, url = {https://m2.mtmt.hu/api/publication/3160859}, author = {Bór, József and Brigitta, Ludván and Péter, Steinbach and Novák, Attila and Barta, Veronika and Sátori, Gabriella}, booktitle = {AGU Fall meeting}, unique-id = {3160859}, year = {2016} } @article{MTMT:3077982, title = {Systematic deviations in source direction estimates of Q-bursts recorded at Nagycenk, Hungary}, url = {https://m2.mtmt.hu/api/publication/3077982}, author = {Bór, József and Ludván, Brigitta and Novák, Attila and Steinbach, Péter}, doi = {10.1002/2015JD024712}, journal-iso = {J GEOPHYS RES ATMOS}, journal = {JOURNAL OF GEOPHYSICAL RESEARCH: ATMOSPHERES}, volume = {121}, unique-id = {3077982}, issn = {2169-897X}, abstract = {Q-bursts are globally detectable extremely low frequency (ELF, 3-3000Hz) band wave packets produced by intense lightning discharges. Q-bursts recorded in the Széchenyi István Geophysical Observatory (NCK, 16.7°E, 47.6°N), Hungary, on 1 and 2 August 2012 have been analyzed to find azimuths of their sources. The location of parent lightning strokes of 320 and 205 Q-bursts on the 2days, respectively, have been identified in the records of the World Wide Lightning Location Network (WWLLN) using the detection times at NCK. ELF data-based source azimuths were found to differ systematically from source azimuths obtained from WWLLN lightning locations. The difference between the corresponding azimuth values depends on the azimuth of the source. This variation of the source azimuth error mirrors the symmetry of the conductance of the Earth's crust inferred from magnetotelluric measurements around NCK. After correction for the azimuthal dependence, the variation of the residual error shows a diurnal pattern with positive azimuth deviations occurring near midnight, local time. Füllekrug and Sukhorukov (1999) suggested that the anisotropic conductivity in the Earth's crust below the observatory and the different daytime and nighttime conductivities in the lower ionosphere, respectively, may cause the identified error terms. Our results emphasize the substantial effect of anisotropic conductivity in the Earth's crust around the recording station on the accuracy of ELF direction finding. The need for theoretical approach and more measurements is pointed in understanding the underlying mechanisms quantitatively and in investigating whether ELF observations can be used in geophysical prospecting. © 2016.
