摘要
对阳江 6 4级地震晚发余震的ML≥ 4 0级地震、频度和前兆震群进行了研究。认为该地震余震序列的频度和强度变化与震区周围的较大地震对应较好 ,其前兆震群和一般小震的前兆震群一样具有前兆意义。它的余震频度、强度和震群活动特征在一定程度上可以显示粤桂琼三省区的地震活动水平并对地震预报有一定的帮助 ,可作为监视粤桂琼地区地震活动的“窗口”。
M L≥4 0 earthquakes, frequency and auspice swarms of late aftershocks of Yangjiang M S6 4 earthquake are study in this paper. The frequency and intensity of this aftershock sequence are corresponding to the earthquakes around it. Some of its swarm is auspicious, just the same as the ordinary earthquake swarms. The activity of frequency, intensity and swarms of its aftershock is beneficial for us to predict the earthquake activities in Guangdong, Guangxi and Hainan regions, and it is regarded as a "window" to monitor the earthquake activities in the three regions.
