汶川8.0级地震前后宏观异常现象分析
|
摘要
文章对2008年5月12日汶川8.0级大地震前后(2008年2月1日至6月10日)出现的宏观异常现象进行了收集整理。较为可靠的异常做为地震宏观异常,并对其时空分布特征进行了研究。研究结果表明,在时间分布上,地震宏观异常的数量在临震前形成一次峰值,震后出现两次峰值;在空间分布上,大震前后宏观异常的空间展布方向趋于一致。文章还对宏观异常的映震机理以及对地震预测可能发挥的作用等问题进行了讨论。
This paper collects and analyzes the macroscopic anomalies before and after the May 12,2008 Wenchuan M8.0 earthquake,Sichuan Province.The credible anomalies occurred from February 1 to June 10,2008 were treated as macroscopic anomalies,then,space-time distribution of the macroscopic anomalies were studied.The results indicate that,in time distribution,the number of macroscopic anomalies reached peak value before the earthquake,and two peak values appeared after the earthquake.In space,the distribution of macroscopic anomalies before the earthquake was the same as after the earthquake.The reason why macroscopic anomalies occurred,the role of macroscopic anomalies in earthquake forecast were also discussed.
