| Abstract: | By use of the regional leveling and GPS observations in Sichuan-Yunnan area during 1994-2006,aided by the negative dislocation model for the elastic block boundaries,combining with the total characteristics of deformation cross-fault,the recent status and intensity of strain accumulation of tectonic blocks and their boundary faults in Sichuan-Yunnan area are studied.The results show that recent status of tectonic stress in Sichuan-Yunnan area manifes itself in energy accumulation mainly.The strain energy accumulation appears obviously in the Anninghe fault and the regions where it meets Zemuhe fault and Xianshuihe fault,the Yanyuan-Lijiang block and its margins,it may be the medium and short-term precursors of some coming earthquakes. |
