Description To investigate crust-mantle interaction of Tan-Lu Fault zone, we contrast a detailed crust-mantle S-wave structure using two dense portable broadband seismic profiles crossing the Dunhua-Mishan fault and Yilan-Yitong fault, supplemented by nearby permanent stations, and combined three-station interferometry (C3) with conventional two-station ambient noise correlation (C2) to generate inter-station Green’s functions between asynchronous deployments. The dispersion data is bandpass filtered at 3 -100 s. The final 3-D Vs model is inverted with the horizontal grid spacing as 0.5°×0.5°, and the depth grid spacing is set to 2.5 km from the surface to 10 km depth, increasing to 5 km between 10–40 km depth and 10 km between 40–70 km depth.
