西藏改则6.9级地震前的电离层电磁扰动
|
摘要
2008年1月9日西藏改则县发生6.9级地震,震前2天法国DEMETER卫星飞过震中上空时记录到离子温度(Ti)和超低频电场异常。文中通过震前10天内多条轨道的数据对比和分析处理,对空间异常的识别和判定给出了两种有效的方法,同时也积累了空间地震电磁前兆震例和异常信号判别的经验。
On Jan.9, 2008, an MS6.9 earthquake of took place in Gaize, Tibet.2 days ago, anomalies of Ti and ULF electric field were recorded when DEMETER satellite of France flew above this epicentral area. In this paper, by means of comparing and processing the data of many orbits during 10 days, two effective methods were provided for distinguishing and determining spatial seismic anomalies. At the meantime, we accumulated the earthquake events with spatial seismic electromagnetic precursors and the experiences in distincting the spatial anomalous signals.
