Abstract:An evolution of activity of main faults in Western Yunnan is inversed by use of the genetic algorithms with the repeat gravity datum from 1985 to 2010 based on the original fault model and consideration for crust layering,viscosity and gravitational effect. The results indicate that the faults have characteristics of reciprocating motion, and reflect well preparation process of earthquakes greater than Ms6.0. There are difference and consistency between the tectonic movement of shallow and deep part of Red River Fault Zone, which regulate the conversion relation by strong earthquake preparation and occurrence. The movement of the faults can be divided into several steps: speed up, speed up to peak value, speeddown, speed up again, speeddown again. Earthquakes occur on the last step.
