本文给出了苏联阿巴斯图马尼天体物理观象台在临震时的夜间气晖光度测量的结果。已经观测到氧绿线(λ=5577A)的强度在地震之前几个小时经历一个最大值,这一上升是由400个小地方震统计分析得出的。氧红线(λ=6300A)与羟基 OH 光谱带的强度却没有明显的异常。所描述的这种现象可能与震源射电辐射引起进入低电离层电子流的增加有关。
In this paper, we present the results of the nighttime luminosity measurement at the Proboscis Center for the Abbasistmani Observatory of the Soviet Union. It has been observed that the intensity of the Oxygen Green line (λ = 5577A) goes through a maximum a few hours before the earthquake as a result of a statistical analysis of 400 small local earthquakes. Oxygen red line (λ = 6300A) and hydroxyl OH band intensity without obvious abnormalities. The phenomenon described may be related to the increase in incoming ionospheric electron flow caused by source radioactive radiation.
