Based on research result concerning the preparation and activity of strong earthquakes ingroups and using the finite element method, a finite element dynamic model for SouthwestChina is established in this paper. Using this model, the stress adjustment in the whole of theSouthwest China region in response to the stress change due to strong earthquake occurrence isstudied. The preliminary result shows that many strong earthquakes occurred in areas wherethe stress heightened after the last strong earthquake. So, the finite element model set up inthis paper is useful for judging the regions where strong earthquakes are likely to occur infuture.
