【摘要】：正地震电磁现象的观测与研究是认识地球内部物质特性、地震孕育发生过程以及空间信号传播和介质特性变化的重要途径。空间对地观测技术的发展,推动了地震电磁信号在大气层、电离层的传播与耦合机制的研究。从20世纪60年代发现美国阿拉斯加大地震震中区上空出现电离层异常扰动现象以来,有关地震空间电磁、电离层扰动的现象引起了广泛的关注,成为地震电磁学领域一个新的研究热点。研究表明,在地震孕育发生过程中,地下介质
[Abstract]:The observation and study of positive seismic electromagnetic phenomena is an important way to understand the material characteristics of the earth's interior, the process of earthquake preparation and occurrence, the propagation of spatial signals and the change of medium characteristics, and the development of space-to-earth observation technology. This has promoted the study of the propagation and coupling mechanism of seismic electromagnetic signals in the atmosphere and ionosphere. Since the discovery of anomalous ionospheric disturbances over the epicentre of the Great earthquake in Alaska in 1960s, the seismic space electromagnetic has been concerned. The phenomenon of ionospheric disturbances has attracted wide attention and has become a new research hotspot in the field of seismoelectromagnetics.
