摘要
本文利用营口市地震台记录到的地震资料,对1975年海城7.3级地震和1999年海城岫岩5.4级地震的活动特征及地震地质背景进行分析。认为这两次地震同属一种类型在不同地段上的地壳应力在不同时间的释放。从中找到它们之间共同的活动特征以及不同之处,这对于本地区地震分析能够起到一定作用。
Based on the seismic data recorded at Yingkou Seismic Station, this paper presents an analysis of the features and geological settings of the seismic activities in connection with two earthquakes that took place in Haicheng respectively in 1995(registered 7.3) and in 1999 (registered 5.4). It is believed that the two earthquakes belong to the same type and are the releases of the crustal stress at different sections and time. The analysis shows the differences and common features between them, which are of helpful application to the seismic analysis in this region.
