AMETHOD TO INVERSE DYNAMIC PARAMETERS OF POTENTIAL SOURCE

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.
