摘要
本文介绍了1987年2月17日江苏射阳5.1级地震的基本参数及中期预报。通过对射阳5.1级地震前短临异常的初步总结,发现短临异常在时间分布上具有阶段性、同步性和相关性,空间分布呈现“多源”前兆场特征。据此,探讨了预报江苏及南黄海的中强地震的可能性。
This paper presents the basic parameters and moderate term prediction of the Sheyang earthquake (M=5.1) on Feb. 17, 1987. Based on the urgent and short anomalies before the earthquake, the author finds that these anomalies have periodicity, synchronism and relativity in temporal distribution and the space distribution appears character of 'multi—source' precursory field. In view of the above, also discusses the possibility of predicting moderate and strong earthquakes in Jiangsu Province and South Yellow Sea areas.
