| 摘 要： | 2006年7月4日河北文安5.1级地震属于孤立型地震,无法根据地震序列提取更多信息,故将该地震与1967年3月27日河间6.3级地震、1973年12月31日河间5.3级地震合并作为一个整体,与邢台地区部分地震作对比分析。由此总结出文安及附近地区地震的活动特点:①呈NNE和NWW共轭分布;②各次地震的时间间隔大幅增长;③余震频度逐渐降低,衰减逐渐加快;④类型向孤立型地震过渡;⑤宏观烈度均比估算烈度低1度左右;⑥震源机制趋于一致。

| Abstract: | Wenan M5.1 earthquake in Hebei on Jul. 4 in 2006 is isolated type, and cannot extract more information from the earthquake sequence, so we combine this earthquake with Hejian M6. 3 earthquake on Mar. 27 in 1967 and the Hejian M5.3 earthquake on Dee. 31 in 1973 as a whole, compared with some earthquakes occurred in Xingtai region, and summed up the earthquake activity characteristics in Wenan and its surrounding area： NNE--NWW conjugate distribution, the earthquake time interval increased significantly, the aftershocks frequency reduced gradually; the attenuation accelerated gradually, transition to isolated types, all the macro intensity was about one degree lower than the estimated; the coherence parameter of focal mechanism became consistent. |
