摘要
2001年11月3日和12月25日在江苏省张家港和南通分别发生ML3 7、ML3 9级地震,南通台体应变观测在这二次地方震前出现了形态相同的突跳性异常变化,对异常进行了分析、判断,排除了环境和气象因素的干扰,认为是这二次地方震的前兆反映。
Two earthquakes (ML37and 39) occurred in Zhangjiagang and Nantong on November 3 and December 25, 2001. The sudden anomalies with same form were observed by body-strain at Nantong station before two local earthquakes. In this paper, we analyzed the body-strain data, and eliminated the interference of environment and weather. We thought that the anomalies were the reflection precursors before the two local earthquakes.
