This paper focuses on the usage of PML method in near-fault earthquake simulations. Combining with velocity-stress hybrid finite element formulation, the applicability of PML is investigated and the numerical reflection of PML is estimated. The reflectivity of PML and multi-transmitting formula (MTF) is compared based on body wave and surface wave simulations. The results show that although PML yields some reflection errors, its absorption performance is superior to MTF boundary in the seismogram simulations, especially in corner and large angle grazing incidence situations. The PML does not arise any unstable phenomenon. The stability of PML is better than MTF boundary in hybrid finite element method. For a specified problem and analysis tolerance, the computational efficiency of PML is only a little lower than MTF.
