反演潜在震源力学参数的一种方法

AMETHOD TO INVERSE DYNAMIC PARAMETERS OF POTENTIAL SOURCE

  • 摘要: 提出利用水准测量资料反演潜在震源力学参数问题,并提出轮回搜索的反演方法,此方法具有搜索范围大,对初始值要求不高,结果比较可靠等优点。根据Alekseev的形变模型,用轮回搜索法,利用1989年大同地震前的水准测量资料(1984~1987)和张北地震前的水准测量资料(1984~1987及1984~1991)对这两个地区潜在震源的力学参数进行实际计算,结果力源中心与后来实际发生地震的震中相差不到40 km。

     

    Abstract: The question to inverse dynamic parameters of potential source is raised, and the inversion method of cyclic searching is al so given.The method has the advantages of large searching range, lower requirement for initial values, and stable results.Based on Alekseev's crustal deformation model and this method, we inversed the dy namic parameters of the potential sources for Datong earthquake (1989) and Zhangbei earthquake(1998).The data we used are the leveling data observed in Datong (1984-1987) and Zhangbei (1984-1991)a rea before the two earthquakes.The results show the difference that the center of the force system we get with the real epicenter is less than 40km.
