000010343 520__ $$2eng$$aAn element refinement algorithm based on sensitivity analysis is proposed and applied to kinematic source inversion analysis. The high sensitivity element on a target fault, which is selected by calculating the Hessian matrix of objective function for the inversion analysis, is divided into two small elements. Optimal element layout based on the sensitivity is obtained by recurring the dividing steps. Numerical examples show that the resolution of slip distributions in the inversion analysis depends on the arrangement of observation sites. It is also found that decreasing the residual between the observed and synthetic waveforms does not always mean improving the estimation of slip distribution.
