Inversion of near-field waveform data for earthquake source rupture process (I): Method and numerical test

摘要: A new inversion algorithm for simultaneously reconstructing the slip vectors and rupture times of a propagating finite fault is developed based on recent progress in nonlinear programming study. To check validity this algorithm, several numerical tests are conducted. The results show that source process computationally efficient numerically stable, depends less initial model compared with two popular methods, i.e. linear matrix method global stochastic search method. Therefore, expected to be useful inverting earthquake processes.
