汶川大地震前后的宇宙线强度变化特性分析
|
摘要
用两种数据处理方法对2008年5月12日14时28分发生的8.0级汶川大地震前和地震发生时北京、广州、Moscow、Irkutsk和Nagoya五个台站的宇宙线变化幅度特性进行了分析.研究发现,地震前、地震时北京台站的宇宙线强度均有一定的响应,其变化幅度分别达到了1.15%,1.31%,而其它台站没有明显的响应,这可能为我们以后利用宇宙线对大地震进行警报提供了研究基础.
Two methods are used to analyze the variations of cosmic rays fluxes of stations at Beijing, Guangzhou, Moscow, Irkutsk and Nagoya before and during the great Wenchuan earthquake on May 12, 2008.Results show that only Beijing cosmic ray data responded to the earthquake in a certain extent.The counting rate increase is 1.15% and 1.31% ,respectively, while other stations data did not, which may be the base of using cosmic rays to alarm intense earthquakes.
