从郯庐断裂(沈阳-渤海段)地质构造和地球物理场特征出发,借助历史中强震复发周期和地震时空分布特征,对该区强震的危险性做了初步分析。结果表明该区6级和7级地震复发周期分别为18年和95年。目前郯庐断裂沈阳-渤海段接近6.5级地震的复发时段,值得注意地区为NNE向郯庐断裂与NW(或NNW)向断裂的交汇部位以及4级地震活动集中区附近。
從郯廬斷裂(瀋暘-渤海段)地質構造和地毬物理場特徵齣髮,藉助歷史中彊震複髮週期和地震時空分佈特徵,對該區彊震的危險性做瞭初步分析。結果錶明該區6級和7級地震複髮週期分彆為18年和95年。目前郯廬斷裂瀋暘-渤海段接近6.5級地震的複髮時段,值得註意地區為NNE嚮郯廬斷裂與NW(或NNW)嚮斷裂的交彙部位以及4級地震活動集中區附近。

Based on the geological structure and geophysical field features of Tan-Lu fault (Shenyang- Bohai section) , a preliminary analysis about strong earthquake risk in the area is made by using the recurrence interval of history medium-strong earthquakes and the characteristics of temporal and spatial distribution. The results showed that M6.0 and M7.0 earthquakes'recurrence interval in this area was 18 years and 95 years respectively. Now it is close to M6.5 earthquake recurrence period of Tan-Lu fault (Shenyang-Bohai section) .The intersections of NNE direction of and NW direction (or NNW direction) of Tan-Lu fault fractures and ME4.0 seismicity concentration areas should be particularly concerned.
