【摘要】 地震事件位置合理性研究旨在对历史地震事件的位置分布规律进行统计分析,从而提供新生地震事件位置是否合理的参考性数据,辅助判断确定性地震事件是否应该给予特别关注。利用格网统计法与密度分析法对历史地震事件的全球分布进行了深入研究,研究结果表明使用1°格网以及0.5°或1°密度分析单元,通过归一化事件数、频度及其时序分析等,可以较好地表征历史地震事件的时空展布特征。更多还原

【Abstract】 The purpose of the research on location rationality of seismic event is to analyze location distribution features of the historic earthquakes,and then,to give the reference level for making sure if the location is reasonable,and finally,to be sure if the seismic event should be given special research.The grid statistic method and density analysis method have been used to research the global distribution features of the historic earthquakes.The result illustrates that the time and space distribution features of the historic earthquakes can be expressed by numbers,frequence and scheduling analysis of events in 1° or 0.5° grid unit.更多还原
