用余震的活动性测定预报参数——在靠近震中区进行测量的可能性很小.震中区有何特点,越靠近震中区的这种效应越强的假设是否合理?直接靠近震中区进行测量是极少的.这些想法是1984年4月20日加兹利地震后余震活动期间在震源进行试验的基础.对电磁辐射异常的观测是在200—1000赫;3—9千赫和80.5千赫((?)f=100赫)3个频段上进行的.高频信号包络线的记录接到КГП—4多频道自动记录仪上,走纸速度为每小时60毫米,每72秒钟在每一通道上取样一次.1984年9月16日～10月18日观测地震活动时发现,余震活动性与前几个月相比呈衰减趋势;但有感地震在几天之内仍不少于1次.在弱震群中1984年9月27日当地时间
Using aftershock activity to determine the parameters of the prediction is less likely to be measured near the epicenter. What are the characteristics of the epicentral region and is the assumption that the stronger this effect, the nearer the epicentral region, is? Very few of them.These ideas are the basis of the experiment carried out at the source during aftershocks after the Ghazli earthquake on April 20, 1984. The observations of electromagnetic radiation anomalies were observed at 200-1000 Hz; 3-9 kHz and 80.5 kHz ((?) f = 100 Hz) over the three bands, the recording of the envelope of the high-frequency signal is connected to the КГП-4 multichannel automatic logger at a speed of 60 mm per hour, every 72 seconds between Sampling once per channel. Seismic activity observed from September 16 to October 18, 1984 showed that the activity of aftershocks tended to decay compared with the previous months, but there was still a lot of earthquakes in a few days In 1.
