摘要
二十年来,我国地学工作者相继对1969年渤海7.4级地震及其前兆现象、震源环境等方面开展了一系列研究和总结,取得了很大进展。本文就渤海地震基本参数的精定结果,震源机制及震源参数测定结果,渤海地震序列的主要特征,渤海地震的震源断层面及其震源环境(地球物理条件和地质构造条件),以及渤海地震的主要前兆异常现象进行介绍和讨论。并指出渤海地震及其所显示的震兆在中国地震预报研究中的作用。
A series of researches and summationes of the 1969 Bohai Sea earthquake (7.4M_S)as well asthe precursory phenomena and the source environment have been carried out for twenty yearsby the earth-scientists of our country with great progress.We will present the results of the re-vised basic seismic parameters,the focal-mechanism and the focal parameters;the principalcharacteristic of the earthquake sequence;the fault-plane and the source environment(geophysical and geological conditions);and the main precursory anomalies.It is suggested thatthe Bohai Sea earthquake as well as its precursors will play an important role in the research ofprediction of earthquakes in China.
