汶川M_S8.0地震前后中国强震时空关联特征研究
|
摘要
本文根据2008年汶川MS8.0地震的发生对我国强震活动产生的影响,从强震诱发和成组孕育理论出发,并结合并行计算和动态跟踪的方法,讨论了该地震发生后全国强震活动形势。后续实发的强震活动验证了该方法在中国内陆强震形势分析上的实效性。文章最后从大震孕育机理的角度对汶川地震前时空关联特征参数(At值)的空间分布特征做了一定的解释。
May 12,2008 Wenchuan earthquake with magnitude MS8.0 brought enormous loss to our country.What about strong seismicity in Chinese mainland after the strong event? This paper discusses this question based on the theory of strong seismic stimulus and characteristics of strong earthquake group preparation,and combining with both parallel computing technology and dynamic seismic tracing.To some extent,the actually strong seismicity after the Wenchuan earthquake validates the study as this paper has shown.At the end of the paper,some characteristics of spatial distribution parameter of spatio-temporal relation of strong earthquakes(At value)before the Wenchuan earthquake were interpreted from a position of mechanism of strong earthquake process.
