大震前后电离层的扰动
IONOSPHERIC DISTURBANCES DURING LARGE EARTHQUAKES
-
摘要: 本文主要分析、讨论了大震前后电离层峰以下的总电子含量、200km 高度处电子浓度以及最大电子浓度所在高度等几个主要电离层参数的变化.对其他电离层直观形态的变化也进行了初步分析.作者认为,地震前的电离层扰动是存在的,并提出了一些可能与地震有关的定性的指标.Abstract: In this paper, variations of the main ionospheric parameters during large earthquakes are analysed and discussed. These parameters are the electron content below the ionospheric peak, electron density at the altitude of 200 km and the height of the maximum electron density etc. The variations of other ionospheric parameters are also analysed. The existence of the ionospheric disturbances has been well verified before earthquakes, and this paper provides some preliminary information for the prediction of an earthquake.
