【摘要】 1990年2月10日01时57分,在江苏省常熟市与太仓县交界处发生了M_s5.1地震。本文对这次地震前兆在时、空、强三个方面的综合特征进行了详细研究,对这些特征在震情综合判定及地震三要素预报中的作用进行了讨论。最后指出,深入研究地震前兆产生的物理机制及其与孕震过程的内在联系,将为地震预报实践提供更加坚实的物理基础。更多还原

【Abstract】 An earthquake Ms 5.1 occurred at the convergent place between Changshu City and Tai-cang County, Jiangsu Province, at 01:57 Feb. 10,1990. This paper studied comprehensive features in time, space and magnitude of the earthquake precursors in detail, and discussed the roles of-these features in seismic condition comprehensive decision and seismic threfe elements prediction. Finally, it is pointed out that further study on physical mechanism of earthquake precursors and its internal link with the seismogenic process will provide solid physical basis for the earthquake prediction practice.更多还原
