On global short-periodic synchronous oscillations of the atmosphere     

Vojtěch Vítek  Reviewer J. Bednář 《Studia Geophysica et Geodaetica》1987,31(3):324-326

Summary The existence of global synchronous atmospheric oscillations with the period of about 1.4 hour is indicated in terms of a simple theoretical model of the circumpolar circulation.

Deep seismically active fracture zones in ecuador and northern peru     

Václav Hanuš  Jiří Vaněk  Reviewer J. Zahradník 《Studia Geophysica et Geodaetica》1987,31(1):8-25

Summary A system of 8 seismically active fracture zones was delineated on the basis of the distribution of earthquake foci in the continental lithosphere of Ecuador. The position and width of the outcrop, thickness, dip and maximum depth of the individual fracture zones were estimated and correlated with surface geological and tectonic phenomena, volcanism and hydrothermal manifestations. The existence and strike of the fracture zones was independently confirmed by the occurrence of historical disastrous earthquakes.

Seismotectonic scheme of Central and Eastern Europe     

Vladimír Schenk  Vít Kárník  Zdeňka Schenková  Reviewer A. Zátopek 《Studia Geophysica et Geodaetica》1982,26(2):132-144

Summary The distribution of earthquake foci in the crust and the upper mantle indicates the position of mobile zones. Comparing epicentral maps of Central and Eastern Europe, known tectonic lines, results of deep seismic sounding and gravimetric survey enables a scheme of potential seismogenic zones, which correspond to active fault zones separating plates and blocks in the area, to be compiled. The level of earthquake activity varies along the investigated boundaries and can be considered as a measure of the intensity of the present geodynamic processes.Paper presented at the joint symposium AlO of the XVIIth General Assembly of the European Seismological Commission and of the 7th Annual Meeting of the European Geophysical Society, Budapest (Hungary), Aug. 21. – 29., 1980.  相似文献

Time pattern of large earthquake sequences in Europe in 1976–1979     

Vít Kárník  Zdeňka Schenková  Vladimír Schenk  Reviewer K. Pěč 《Studia Geophysica et Geodaetica》1982,26(1):42-58

Summary The time development of three large sequences, Friuli 1976, Thessaloniki 1978 and Monte Negro-Albania 1979, was investigated by analysing the characteristics of the time distribution of magnitudes of the events, M(t), of average magnitudes, (t), and of the number of events, n(t), as well as the strain release curves and the magnitude-frequency relations, N(M). The existence of time gaps and of an anomalous decay of the numbers of shocks before major events, as well as the oscillation of ( const b^–1) may be considered as precursory phenomena. The clustering of events has been tested by the Poisson and negative binomial laws.Communication presented at the XVIIth General Assembly of the European Seismological Commission in Budapest, 21–29 August, 1980 under the title Properties of Seismic Regime and Recent Earthquake Sequences in Europe.  相似文献

Earthquakes in the Czech Republic and Surrounding Regions in 1995–1999     

Zedník  J.  Pospíšil  J.  Růžek  B.  Horálek  J.  Boušková  A.  Jedlička  P.  Skácelová  Z.  Nehybka  V.  Holub  K.  Rušajová  J. 《Studia Geophysica et Geodaetica》2001,45(3):267-282

In the time span from January 1995 to December 1999 the Czech National Seismological Network (CNSN), consisting of ten permanent digital broadband stations, several local networks and two data centers, detected and recorded 9530 regional natural seismic events, 27 greater than magnitude 2. Most of these events were located by the Czech Seismological Service (CSS), and the most prominent of them were analyzed in detail. A large number of quarry blasts were recorded as well but were not included in the analysis. We provide basic information on the configuration of the CNSN and on the way of routine data processing employed by the CSS in this paper. The over-all regional seismicity monitored by the CNSN in 1995–1999 is briefly reviewed. The main results of observations and evaluation of the local (NW-Bohemia/Vogtland, South Bohemia, Sudeten) and induced (Kladno, Píbram, Upper Silesia, Lubin/Poland) seismic activity within this period are presented in a condensed form. Finally, a summary on macroseismic observations on the territory of the Czech Republic in 1995–1999 is also presented.  相似文献   

Comparison between Pollutant Concentration in the Samples of Fog and Rime Water Collected at Mt. Milešovka     

Fišák  Jaroslav  Řezáčová  Daniela 《Studia Geophysica et Geodaetica》2001,45(3):319-324

The article aims at showing the differences in concentration of pollutants that are contained in the samples of fog and/or low cloud water in comparison with the water from rime. The results follow from the fog and rime measurements made at Mt. Mileovka (eské Stedohoí Mountains). They are compared with the results of other studies that also report the differences in fog and rime chemistry.  相似文献
