Резюме Нзменение амплитуд объемных волн с расстоянием было изучено на основании б аемлетрясений, регистрированных 30 сейсмическими
станциями в эпицентральных расстояниях<30°. Из рисунков видно, что амплитуды продолных и поперечных волн меняются в изучаемых
расстояниях подобным образом, но минимум и максимум кривой (A
*, Δ) для волнSH подвинуты к ббльшим эпицентральным расстояниям чем в случае воумPH.

Summary The core waves recorded at four seismograph stations in Central Europe were investigated with the aim to find the most suitable set of travel-time curves and a fitting model of the core structure. Another travel-time curve was constructed by means of time differences between the core phases. The differences in the features of the travel-time curves were studied using records of shallow, intermediate and deep shocks from the same focal region (Tonga). 相似文献

The routine location of regional seismic events using data from the Czech National Seismological Network (CNSN) is based on Pn, Pg, Sn, Sg phases. A simple velocity model derived from Kárník's (1953) interpretation of an earthquake in Northern Hungary in 1951 has hitherto been used. At present, numerous local seismic networks record and locate local events, which are occasionally recorded at regional distances as well. Due to the relatively small dimensions of local networks, hypocenters (and origin times) determined by a local network might be considered as nearly exact from the point of view of regional-scale CNSN. The comparison of common locations performed by CNSN and by a local network enables us to estimate the accuracy of CNSN locations, as well as to optimize a simple velocity model. The joint interpretation of the CNSN bulletin and the catalogues of four local seismic networks WEBNET, OSTRAVA, KLADNO and LUBIN produced a new ID velocity model. The most frequent epicentral error in this model is less than 5 km, and most foci lie up to 15 km from the true position. The performed analysis indicates bimodal distribution of Sn residuals. 相似文献

Summary PKP-amplitudes of about 400 earthquakes from the SW Pacific Ocean observed at three stations in Central Europe were used to obtain the calibration function qPKP(D, h) based on the NEIS mb magnitudes. The calibration function allows us to determine the magnitudes for week earthquakes from the Pacific, for which the magnitudes from the P-waves cannot be derived. 相似文献

Summary The records of the first series of the North-Italian aftershock series from the period May–August 1976 at the stations Prhonice and Kaperské Hory were analyzed from the point of view of the verification of the travel-time tables used for the interpretation of near earthquake seismograms and of the determination of the short-period body wave magnitudes for near shocks. Also the time-energy distribution was investigated for a 90 days period. 相似文献
