摘要： 借鉴已有研究成果,进一步对渤海周围地区地震构造带的分布、区域构造背景及其活动性做了分析,在此基础上,对张北6. 2级地震前至目前,华北北部前兆异常的总体数量及其沿地震构造带分布的变化,以及该区主要地震构造带的地震危险趋势进行了分析研究。

Abstract: Using the previous re searches as reference, we analyzed the distribution of the seis-mic tectonic zones around Bohai Sea, regional tectonic background and its activity. Basedon the analysis, we studied the variation about the total members of the precursory anomalies, which have occurred in the north of North China before Zhangbei 6. 2 earthquake till now, and the distribution of the anomalies along the seismic tectonic zones. Finally, we conducted the re search on the tendency of seismicrisk along the major active tectonic zones.

Key words: Seismic tectonic zone, Distribution of precursory anomalies, Evaluation for the tendency of seismicrisk, Bohai Sea area
