文章介绍了阿拉木图地震预报实验场中3个电磁辐射台站(卡斯杰克、吐尔盖尼和天山台)1995年的观测资料。台站使用综合程序仪器,以连续方式用1、2、4、8、16、32、64、128、256、512、1024μs波段记录电磁辐射脉冲信号,并用带通滤波处理资料。结果发现,在阿拉木图实验场发生的地震事件之前,大多数记录频段上出现了电磁辐射强度的异常增大。文章认为电磁辐射场的变化从总体上反映了北天山地壳的地震动态变化。
This article presents the 1995 observations of three electromagnetic radiation stations in the Almaty earthquake prediction experimental station (Kasjak, Torghani and Tien Shan). The station uses the integrated program instrument to record the electromagnetic radiation pulse signals in a continuous manner using the bands of 1, 2, 4, 8, 16, 32, 64, 128, 256, 512 and 1024 microseconds and process the data by band-pass filtering. It was found that anomalous increase in electromagnetic radiation intensity occurred in most recorded bands prior to the seismic event at the Almaty Experimental Site. The paper holds that the change of the electromagnetic radiation field generally reflects the seismic dynamic change of the North Tianshan crust.
