研究了利用强功率源超低频无线电装置监测地震活动性的前提。这种装置能产生谐波可变超低频电磁场。给出了所利用的АКФ-2型测量仪器的简单特性。分析了在北高加索进行实验的一些结果。证明了在接近装置方向图最小方向上(天线系统的赤道区)记录2700 km远处超低频无线电装置信号的可能性。判定了能显示出用超低频无线电装置预报地震前景的阻抗的时间稳定性。比较了超低频无线电装置电磁场和天然电磁场测量的结果。
The premise of monitoring the seismicity by using ultra-low frequency radio with strong power source was studied. This device can produce harmonic variable ultra-low frequency electromagnetic field. The simple features of the АКФ-2 measuring instrument used are given. Some results of experiments conducted in the North Caucasus have been analyzed. Proved the possibility of recording the signal of a subwoofer radio at 2,700 km away in the direction of the smallest of the device pattern (equatorial region of the antenna system). It was determined that the time stability of the impedance that can predict the foreground of the earthquake with the ultra-low frequency radio device is shown. The results of electromagnetic field measurement and natural electromagnetic field measurement of ultra-low frequency radio are compared.
