川滇交界中段历史强震及其活动特征

本文在详细补充调查和充分整理前人资料基础上，对川滇交界中段的其中６次强震进行了等烈度图编制，并对川滇菱块东界大地震的等烈度线分布特征进行了研究，按照构造孕育与发震扩展的思路，探讨了川滇交界中段的中长期地震危险性。     

四川中强地震特征性活动图象与当前地震趋势讨论

本文从四川Ｍ≥４级地震时、空、强活动图象分析中，提取了有重复性前兆意义的异常图象，称为特征活动图象，如条带状、丛集、环状围空、缺震异常时段、盆地及周缘区前震等。并根据当前的地震活动图像，讨论了四川地震趋势。     

Analysis of Geological Background of Seismic Activity in the Chengdu Plain from Data of Seismic Prospecting for Oil

Summarizing the existing data of seismological and geological investigations and of strong and intermediate-strong earthquakes in‘ the Sichuan basin and its adjacent areas accumulated by the seismological and petroleum organizations in Sichuan and of the results of seismic prospecting and detailed exploration in Chengdu depression during the last 20 years permitted us to studythe types and distribution of hidden structures in Chengdu depression and its adjacent areas, in particular, to identify in, detail the “hidden faults” in the Chenngdu-Deyang area on the one hand; The obtained data indicate that the NE-trending Xinjin fault ruus northward and dies out in the south of Penzhen town of Shuangliu County; Meanwhile, we studied genetic relations of seismic activity to active faults and their corresponding movernent charaeteristics on the other hand, Moreover, the Surface faults and deep-seated faults are clearly defined and outlined,and 5 types of seismogenic faults suggestd. The knowledge thus obtained enables us to delimit the focal zones for potential strong earthquakes in Chengdu depression. The study suggests that a zone of 40 km wide and more than 100 km long on sides along the Chengu Deyang lim bas a stable seismogeological background and good engineering-seismological conditions.     

川滇当前强震活动图象与地震趋势

本在研究中国大陆中国南北地震带及川滇地震区新的经震活动幕（１９８０－１９９６年前后）主要强震活动图象特征及其变化的基础上,提出了地中短期强震趋势预测的几项强震活动图象指标,据此川滇当前强震趋势作了初步的预测与讨论。
