Delineating the finestructure of fault is necessary to understand the process of earthquake occurrence. Fault zone waves which consist of fault zone head waves propagating along material discontinuity interfaces, direct body waves propagating within a low-velocity fault zone and trapped waves due to seismic energy trapped in a low-velocity fault zone are sensitive to a structure of fault zone. The modeling of these waves is one of the useful procedures to reveal a fine structure of fault zone. We use the 3D finite difference (FD) method to simulate fault zone waves and to determine a fault zone structure. A linear array consisting of 32 three component seismometers spacing roughly 15m is across the Mozumi-Sukenobu fault in research tunnel at a depth of 300m. In previous study, using the se
