摘要
从地震构造带的历史和现代的地震活动分析入手，并通过对邢台地震、渤海地震、海城地震、唐山地震的震例分析，对当前地震前兆趋势异常的特征进行了地质解释，认为在今后张家口－唐山－渤海地震构造带上的蓬莱－铜井断裂，芝罘－威海断裂、海西头一俚岛断裂发生地震的可能性最大。
Kind of anomalies including microseismicity and earthquake precursors appearedaround Bohai Sea area from November 1995 to March 1996. on the bases of the study onseismotectonics, historical and present seismic activity, the geological features of the ex-isting anomalies have been studied and explained by compared with results of previousearthquakes, such as Xingtai, Bohai, Haicheng and Tangshan earthquakes. The conclu-sion is that the Penglai-Tongjing fault, the Zhiluo-Weihai fault and the Haixitou-Lidaofault along the Zhangjiakou-Tangshan-Bohai seismic zone are the most dangerous faultswith higher probability for earthquake occurrence.
