引言新疆从７０年代组建地震队伍起,就开始进行测震观测和数据处理工作,其间积累了许多地震资料。在两次审编地震目录后,出版了１９７０～１９７９年和１９８０～１９８４年新疆地震目录,在国际合作项目中完成了天山地震目录的编制工作。从１９８６年引进ＢＬＯＣ８６定位程序后,到１９９４年１２月在编目日常工作中开始运行自行研制的新疆测震数据处理系统,整个编目工作经历了技术水平逐步提高的进程。在现阶段,建设完善的以实用软件为纽带的新疆测震数据工作系统至关重要,笔者试就这些问题谈谈新疆测震数据工作取得的新进展。１ … 相似文献

Introduction Earthquake is a destructive natural disaster. Earthquake studies are very complex, which not only involves space and time of large size, but also requires vast amount of spatially referenced data, such as historical records, modern instrument data, scientific experiment data and a lot of other data coming from related subjects. GIS, as an integrating tool processing multi-source data, has become a key technology in earthquake studies. In recent years, many GIS application system… 相似文献

We have updated the active fault map of Turkey and built its database within GIS environment. In the study, four distinct active fault types, classified according to geochronological criteria and character, were delineated on the 1:25,000 base map of Turkey. 176 fault segments not included in the former active fault map of Turkey, have been identified and documented. We infer that there are 485 single fault segments which are substantially potential seismic sources. In total 1964 active-fault base-maps were transferred into the GIS environment. Each fault was attributed with key parameters such as class, activity, type, length, trend, and attitude of fault plane. The fault parameters are also supported by slip-rate and seismogenic depth inferred from available GPS, seismological and paleoseismological data. Additionally, expected maximum magnitude for each fault segment was estimated by empirical equations. We present the database in a parametric catalogue of fault segments to be of interest in earthquake engineering and seismotectonics. The study provides essential geological and seismological inputs for regional seismic hazard analysis of all over Turkey and its vicinity. 相似文献

—?A computerized application of an integrated seismological GIS model is presented. An object oriented approach of the GIS topology is introduced and the special functions and features of this system are described. A network topology was selected to simulate the network characteristics of seismological data management and analysis. Each seismological entity is considered as a graphical data object, which is associated to other objects by predefined relationships. The graphical user interface introduced by GIS enables to handle seismological software routines and data in a more intuitive way. Examples of interactive processing of seismic waveforms for detecting, locating and characterizing seismic events using GIS visualization capabilities are presented. The benefits of this system during a passive seismic survey in the framework of the CTBT are highlighted. 相似文献

We analyzed the International Seismoogical Center(ISC)catalogue of seismologil publicationsfrom 1980 to 1995 to investigate how much infonformation provided by an earithquake hes beenutilized to obtain a better undertanding of earthauakes and selsmic disaster.We sekect the ISCbulletin which has a wider coverage of seismological journals and languages than the ScientificCitation Index(SCI),so that there is less regional or language bias in the analysis.The earth-quakes in the catalogue span the period from 1975 to 1990.Papers which have direct relationwith an earthquake as defined by the ISC catalogue range from 1 to 10~2 in order of magni-tudes.The logarithm of the maximum number of papers on an earthquake is shown to be prop-ortional to the magnitude of the earthquake,which provides a possibility to define a“normali-zed impact strength”of an earthquake,so that earthquakes with different magnitudes can becompared with each other.Magnitude span of the earthquakes with a certain“impact strengthlevel”an 相似文献

The behavior of the Gutenberg-Richter distribution (the frequency-magnitude relation for the earthquakes) in response to advancing the system of seismic observations and applying various methods for estimation of the Gutenberg-Richter b value is studied. The long highly accurate time series of seismological measurements at the Garm geophysical testing site in Tajikistan is an input for the study. We analyzed the data from the detailed catalogue of earthquakes with magnitude M = 0?C5 that occurred within the test site from 1955 through 1992. It is shown that the changes in the design of measurements both as to the number of observation sites and as to the measurement capacities during the development of the seismic network in 1955?C1966 have strongly affected the content of the catalogue. Our study revealed spatiotemporal changes in the minimum magnitude of completeness, which were associated with advancing the design of observations. We have analyzed the accuracy of the calculation of the b value as a function of the reliability of determining the actual minimal magnitude of completeness (the cutoff magnitude) for the catalogue (Mc), the method of calculation of the b value, and the volume of the spatial sample of the earthquakes used. It is established that the pattern of horizontal distribution of the b value is closely correlated to the tectonic structure of the test area, while its vertical distribution distinctly reflects the crustal waveguide at a depth of 9?C17 km, which has been previously revealed approximately in this depth interval according to other seismological data. This suggests that, in the first approximation, the lateral and vertical variations in the b value observed in our study are caused by the changes in the strength properties of the crustal material, namely, by the increased plasticity of the rocks within a thick sedimentary layer and in the waveguide. 相似文献

Artificial earthquake catalogue simulation is one of the ways to effectively improve the incompleteness of the existing earthquake catalogue,the scarcity of large earthquake records and the improvement of seismological research.Based on the Poisson distribution model of seismic activity and the Gutenberg-Richter magnitude-frequency relationship, the Monte Carlo method which can describe the characteristics of the stochastic nature and the physical experiment process is used.This paper simulates the future seismic catalogues of the Fenhe-Weihe seismic belt of different durations and conducts statistical tests on them. The analysis shows that the simulation catalogue meets the set seismic activity parameters and meets the Poisson distribution hypothesis,which can obtain a better simulated earthquake catalogues that meets the seismic activity characteristics.According to the simulated earthquake catalogues,future earthquake trends in this region are analyzed to provide reference for seismic hazard analysis. 相似文献

The China‘ s Earthquake Cases and Disaster Information System based on GIS (MapECDIS2002 for Windows) is a GIS system developed to provide a tool for the government and the public to inquire and learn about disaster information (since 2221BC) and case study results (since 1966) of destructive earthquakes in China. The system is expected to be helpful, as an applied supplementary tool, for scientists and management personnel in earthquake prediction practice, seismological research and earthquake disaster research. The design idea and main functions of the system are introduced in the paper. 相似文献
