| 摘 要： | 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。

| Abstract: | In this paper,the anomaly patterns to have repeatability precursor significance are obtainedaccording to the acctivity pattern analysis on time-space-intersity of M > 4 earthquakes inSichuan. The patterns are called as character activity patterns,such as the seismic band,the seis-mic clusters,the seismic gap of ring,the anomaly period of earthquake abstent and the foreshockin basin and neighbourhood. The seismic trend in Sichuan is discussed in this paper based on cur-rent seismicity pattern. |
