摘要
Using the velocity field result of horizontal movement observed by GPS in the periods of 1999～2001, 2001～2004 and 2004～2007, based on the inversion of aseismic negative dislocation, strain accumulation of the main boundary faults and their time-space evolution features are researched. Possible influences of the Ms8.1 earthquake at west the pass of Kunlun Mountains on Nov.14, 2001 and the Sumatera Ms8.7（Mw9.0） earthquake on Dec.26, 2004 are analyzed, together with the strain accumulation background related to the Wenchuan Ms8.0 and the Panzhihua-Huili Ms6.1 earthquakes in 2008.
