几次中强地震前电磁波异常的初步分析
|
摘要
2008年新疆新建轮台、喀什、阿图什3个电磁波观测台站,经过1年多的观测,喀什、阿图什2个台站资料较为连续、可靠。台站400 km范围内的5次5级以上地震前,电磁波具有明显的短临异常特征。阿图什、喀什2个台站电磁波最大值的异常图像虽有一定差异,但均有重复性。阿图什电磁波异常形态为上升—下降的高值变化过程,而喀什电磁波异常形态主要为高值突跳。异常时间一般出现在震前10 d内,具有较好的临震指示意义。
Three observation systems of CNEM-08-I electromagnetic wave in Kashi langan village,Artux gedaliang village and Luntai county in 2008 were builded.The time of observation had passed about a year,observation datum of Kashi and Artux are good continuous and reliable.During observation,five MS≥5 earthquakes occurred nearby 400 km,electromagnetic wave show imminent anomaly.Artux's anomaly characteristics is raise and down with high value quickly,Kashi's anomaly is mostly skip with high value.The anomaly appears less than 10 days before medium-strong earthquake.It is indication meaning for short-impending forecast.
