Abstract We take the GPS stations speed field in the Sichuan-Yunnan region as constraints and combine them with the known situation of fault distribution in the study region. Then, by using the Euler vector calculation and reversed Euler vector calculation methods, we get the Euler vector of each sub block. We make further adjustments to the Sichuan Yunnan region of sub blocks. We make a 1°×1° grid interpolation for the region, and reverse the long-term movement direction and speed of each sub block by using the Euler vector of each sub plate. With regard to the boundary of neighboring blocks, combining the Euler vector of respective blocks, we calculate the speed of the same point in the two blocks and subtract. Then we analyze the current rate of the main fault region.
