Summary The investigated region covers the territories of Bulgaria, Czechoslovakia, the G.D.R., Hungary, Moldavia, Poland, Romania and the south-western Ukraine and parts of Austria, Greece, and Yugoslavia. Maps of epicentres demonstrate the geographical distribution of activity. Earthquakes occur in several seismogenic belts (provinces) related to neotectonic features of the region. A special phenomenon is the intermediate-depth focus of Vrancea releasing in the region the largest amounts of energy, together with a few crustal foci in Bulgaria. 相似文献

Summary Amplitudes and periods of seismic waves recorded both in the short-period and in the intermediate-period ranges at the seismic stations Prhonice, Praha and Kaperské Hory are influenced by the tectonic situation in the focal regions rather than by the anisotropic structures of the geologic formations underlying the stations. Large amplitude variations and differences in periods due to instrumental effects were also found. 相似文献

Summary An attempt was made to verify the possible influence of seismograph characteristics on the first displacement in the P wave. The signals recorded by the broadband seismic channels at Kaperské Hory were treated by a set of pass-band filters, three of them simulating the usual types of seismographs. 相似文献

Summary The errors in determining the partial constants of a seismometer using the method of recording the free oscillations of the seismometer by a galvanometer are analysed and the maximum values of the coupling coefficients at which the derived seismometer constants do not differ from the partial by more than 1%, are computed. 相似文献
