摘要
本文对全国历史地震资料的有用信息作了进一步的开发和利用,按统一方法处理了大量有感以上地震的文字记载,确定了每个独立地震的时间与地点;分区求得地震的有感区长半径与震级的关系式;确定了历史有感地震的最低震级为4;取得了8000余次有感地震的基本参数;用等震线测定了巨大地震的震源参数;将有感地震目录与强震目录统编成全国与几个大区M>4.0地震目录,按《地震学地震预报实用程序系统》(EPSEIS)的格式要求建库;同时编制出两套汉字系统地震目录,为全面、系统研究全国强震前后地震活动图象特征提供了有利条件。
This paper furthur developed and used the availiable information of seismic historical data in China . We deal with a large number of detectable recorded earthquakes, determined the original time and epicentral location of each independent earthquake,and acquire the relational formula between the long semi-axis of felt area and the magnitude of earthquake in different regions, define the minimum magnitude of historical felt earthquakes is 4, obtain the basic seismic parameters over 8000 felt earthquakes and determine the source parameters of the great earthquakes by the isoseismic lines, compile the national and several great zonic catalogues (M≥4.0) by adding the felt earthquakes' catalogue to the strong one, and make data base in EPSEIS's format. Besides, two catalogues in Chinese have been edited, which provide the advangtageou condition to study the seismicity features comprehensively and systematically before and after strong earthquakes.
