溧阳地震台体应变测量与南黄海中强震对应关系的分析

Analyses of the Corresponding Relationship between Volumetric Strain Anomalies Observed at Liyang Seismic Observatory and Moderate- Strong Earthquakes Occurred in Southern Yellow Sea Area

一、引言溧阳地震台体应变观测投入运行以来,积累了连续可靠的观测资料。分析研究这些资料可以看到,南黄海的数次中强地震,溧阳台体应变观测都有十分明显的异常反应,总结溧阳台体应变异常与南黄海中强地震之间的对应关系,能更为有效地对近区中强地震产生的前兆反映进行对照分析和预测。二。

The basic regulation and features of volumetric strain anomalies observed at Liyang seismic observatory before and after each of the earthquakes with M≥4 occurred in southern Yellow Sea area since 1996, have been studied in this paper. The results show that there have existed a certain precursory anomalies at Liyang seismic observatory to those earthquakes.
