| 摘 要： | 本文总结了国内外关于地震电离层扰动现象研究的主要进展,主要介绍了法国DEMETER卫星及其相关的统计研究和震例研究成果,总结了目前地震电离层扰动前兆震例研究的一般步骤,介绍了地震孕育过程中产生的电磁异常信息向电离层传播的可能途径,包括化学途径、声学途径和电磁途径.大量的研究成果表明地震电离层异常的存在,在地震发生前几个小时至几天或几个月电离层扰动被探测到,但是地震电离层扰动前兆能否作为地震预报方法,还有许多需要深入研究的问题.本文提出了地震电离层研究需要解决的几个重要问题.

| Abstract: | In this paper,we review recent advances and latest developments on the study of ionospheric disturbances prior to earthquakes.We also introduce DEMETER satellite and some statistical studies and earthquake case studies based on DEMETER satellite data.The common steps for studying ionospheric phenomena before strong earthquakes are expounded: select the earthquake examples-choose the parameters of the ionosphere-data analysis,extract and identify disturbance information-validate pre-earthquake ionospheric responses.The electromagnetic effects and correlated phenomena generated in seismo-electromagnetic process,spread to space by ways of chemistry,acoustics,and electromagnetism.The research results show clearly that ionospheric disturbances appearing several months,days or hours prior to earthquakes can be observed.whether the precursors could be used as a tool in earthquake prediction need more research. |
