Abstract	In order to extract surface waves more effectively and improve the accuracy of detection in a microtremor survey, the staggered grid finite difference method for forward modeling of microtremor wave field was proposed. The finite difference form of wave equation was derived from the staggered grid built, and then the split form of finite difference equations was developed based on perfectly matched layer condition. Forward modeling test was carried out on the homogeneous, two-layer medium and the thin multilayer medium half-space, respectively. The results show that the forward modeling of microtremor wave field can get a more realistic signal, and provide a theoretical base for data processing and analysis.
