Atmospheric tide obtained by the microbarograph developed at the Geodetic and Geophysical Research Institute of the Hungarian Academy of Sciences
Acta Geodaetica et Geophysica Hungarica - Tập 39 - Trang 39-48 - 2013
Gy. Mentes
The air pressure variations due to lunisolar effects cause a part of the deformation of the Earth and therefore directly and indirectly influence several geodynamical phenomena. For a better understanding of these effects a microbarograph of high sensitivity was developed at the Geodetic and Geophysical Research Institute of the Hungarian Academy of Sciences in 1991. In this paper the construction...... hiện toàn bộ
Identification of local seismicity observed south of Aswan city — Egypt
Acta Geodaetica et Geophysica Hungarica - Tập 43 - Trang 93-103 - 2013
S. A. Dahy, G. H. Hassib, Abdel-Monem S. Mohamed, A. Hassoup
Suddenly, Aswan Seismic Network detected and observed a number of events beside Aswan city. The magnitude of these events ranged from 0.9 to 2.6. These events were considered very important events because they were located not far from the Aswan High Dam. The main purpose of this work is to investigate and identification of these events using different seismic methods. Small earthquakes and explos...... hiện toàn bộ

Effect of positional inaccuracies on multielectrode results
Acta Geodaetica et Geophysica Hungarica - Tập 43 - Trang 33-42 - 2013
S. Szalai, A. Koppán, L. Szarka
This paper investigates the effect of electrode positioning errors on the inverted pseudosection. Instead of random spacing errors (as usually assumed in geoelectrics) we exactly measured this effect among field conditions. In the field, in spite of the greatest possible care, the electrode positions contain some inaccuracy: either in case of dense undergrowth, or varied topography, or very rocky ...... hiện toàn bộ
Research for seismogenic zones in the Pannonian Basin — a deterministic seismic hazard estimation for Budapest
Acta Geodaetica et Geophysica Hungarica - Tập 36 - Trang 417-438 - 2013
Gy Szeidovitz, Z. Bus, K. Gribovszki
In this paper, a theory describing the possible origin of shallow depth earthquakes occurring within the sedimentary depressions of the Pannonian Basin is presented. In addition, the seismicity of Budapest is re-evaluated by synthetic seismogram based deterministic seismic hazard estimation.
Effectiveness of the surplus error method in function of the numberNof the applied surplus error sets

Nighttime Enhancements in IEC at Low Latitudes — A Study with Reference to F Region Dynamics
Acta Geodaetica et Geophysica Hungarica - - 2013
D. S. V. V. D. Prasad, P. V. S. Rama Rao, P. Sri Ram, K. Niranjan
The nighttime enhancement (NTE) in the ionospheric electron content (IEC) are observed over Waltair (17.7°N) and Calcutta (22°N), when the equatorial F region rises to higher altitudes during the post-sunset hours over Kodaikanal (10°N). No significant enhancement is seen at either of the stations if the altitude of the F region near the equatorial region is confined to lower altitudes. In additio...... hiện toàn bộ
Evidence of strong lateral inhomogeneous structure beneath SE Carpathians and specific mantle flow patterns
Acta Geodaetica et Geophysica Hungarica - Tập 43 - Trang 119-130 - 2013
F. Borleanu, M. Popa, M. Radulian, C. Panaiotu
The Vrancea region, in the South-Eastern Carpathians (Romania), represents a unique case among the seismic areas in the world taking into account the extreme concentration and persistence of seismicity and tectonic stress field. Our goal is to show that the particular shape of attenuation and shear wave splitting properties can be interpreted in the light of the decoupling and slab retreat process...... hiện toàn bộ
Historical Seismicity of Egypt
Acta Geodaetica et Geophysica Hungarica - Tập 34 - Trang 119-135 - 2013
A. Badawy
The historical earthquakes that have been felt in Egypt were compiled from Arabic documents and earlier earthquake catalogues. About 83 earthquakes were found during the period from 2200BC to 1899AD. The time distribution of these earthquakes shows that, only seven earthquakes have been reported in the period before Christ (BC). Up to the end of the ninth century the secular number of reported ear...... hiện toàn bộ
Rediscovering the old treasures of cartography — What an almost 500-year-old map can tell to a geoscientist
Acta Geodaetica et Geophysica Hungarica - Tập 44 - Trang 3-16 - 2013
B. Székely
Tabula Hungariae (1528), created by Lazarus (Secretarius), is an almost 500 year-old map depicting the whole Pannonian Basin. It has been used for several geographic and regional science studies because of its highly valued information context. From geoscientific point of view this information can also be evaluated. In this contribution an attempt is made to analyse in som...... hiện toàn bộ
