The algorithms to evaluate seismic hazard, used and/or developed by five teams participating in the TERESA project, applied to the low seismicity area Belgium, The Netherlands and NW Germany are compared. The main differences in the results can be explained by the majority criterion of Egozcue et al. (1989), the differences in the upper bound and zonification and, in some cases, by a higher attenuation. 相似文献

Within the activity of the ESC Subcommission 8 Engineering Seismology, Project TERESA, seismic hazard calculations have been performed for two areas of a different earthquake activity. Fundamental seismological data (earthquake catalogues, macroseismic observations and maps) and some additional geological information were analyzed and processed to prepare inputs for hazard computations. Great attention has been paid to verifying the reliability of the input data. Seismic hazards obtained for five sites of the region of high seismic activity (Sannio-Matese, southern Italy) and six sites of the region of low seismic activity (Brabant Massif and northern Rhine, Belgium—The Netherlands—Germany) are presented and discussed. 相似文献

Macroseismic intensity, a useful measure of earthquake effects, is still applied in a wide range of seismological applications
like seismic hazard assessments, attenuation relationships, etc. Isoseismals represent the spatial distribution of macroseismic
intensities, and their shapes depend on source properties, lithosphere structures, tectonic line orientations, site geology,
and topography. The applications ask for both the higher number of isoseismal maps, and their standardization and homogenization.
The point kriging gridding method for an automatic computer drawing of isoseismal maps was delivered. Smoothing rates and
numerical parameters used in the kriging algorithm were tested on macroseismic data of Greek earthquakes representing different
tectonic and geomorphological regimes. The optimum kriging default option was defined. Its application for four Greek earthquakes
is presented and discussed from the viewpoint of a broad use in recent macroseismology.

Qualitative geological acceptance criteria and quantitative seismological acceptance criteria for radioactive waste disposals are developed. The background material for the initiation of site selection and for its earthquake hazard assessment is discussed. The recent movements of the Earth's surface as well as the other mechanical properties of geological media, hydrological conditions of geological blocks, their groundwater chemistry, geochemical rheology, petrological analyses of rocks, etc., have to be taken into account. A new comprehensive integrated safety analysis of the final underground disposal of spent nuclear fuel has been underway in the Czech Republic since 1991. In accordance with these seismogeological acceptance criteria regions for building underground final radioactive waste disposals are singled out in the Czech Republic. 相似文献

The cross-bordering earthquake hazard mapfor three Central European countries, the CzechRepublic, Poland and Slovakia (CZ-PL-SK) in thesense of the Global Seismic Hazard AssessmentProgram (GSHAP) was elaborated both in terms ofmacroseismic intensities and in terms of peak groundaccelerations (PGA). A new earthquake parametriccatalogue for CZ-PL-SK (Schenková et al., 1999)allows the source regions to be delineated withrespect to tectonic structures. Regions for Austriaand Germany were taken from the D-A-CH area withsome modifications in the border zone with the CzechRepublic and Poland. Regions of other surroundingcountries were defined with respect to nationalearthquake catalogues and geologico-geophysical dataof Central European countries. For each sourceregion earthquake data were normalised to obtain areliable annual recurrence graph and the maximumexpected earthquakes. Attenuation laws were definedto allow more advanced earthquake hazard maps to becalculated by the standard probabilistic McGuire's(1976) approach. The obtained GSHAP hazard maps forthe CZ-PL-SK area were calculated for the returnperiod of 475 years. Besides a comparison with thehazard values for the D-A-CH area (Grünthal etal., 1995, 1996; Grünthal, 1997), the map wasalso compared with the effective ground accelerationmap for Austria (Lenhardt, 1996) and in both cases avery good coincidence was found.Author for correspondence 相似文献

Probabilistic hazard calculations were tested with respect to input data uncertainties. Statistical approximations of input data allow the regression coefficients and their standard deviations to be determined. Since inaccuracies of the regressions closely depend on the input data uncertainties, the standard deviations of the individual coefficients were used as a measure of input data parametrisation. Differences in the hazard outputs, caused only by various combinations of the regression coefficients and their standard deviations determined for the cumulative recurrence graph and the attenuation law, were studied. It was concluded that the hazard calculation conditions should be (a) strictly defined and always quoted with every hazard assessment, and (b) standardized in order to establish a common liability of earthquake hazard calculations. The established categorisation of the earthquake hazard assessments divides the probabilistic hazard calculations according to their reliability and helps users to apply them in earthquake engineering practice. The credible hazard assessments corresponding to 90% probability can be recommended for common structures whereas the maximum credible hazard assessments coinciding with 95% probability yield values close to hazard assessments of important structures, hospitals, bridges, etc. 相似文献
