  • Abstract This study is use BATS date calculate the three dimensional shear wave velocity structure of the crust under the Taiwan region. First use PMF to get group velocity dispersion of fundamental mode Rayleigh waves. Then, block inversion method was applied to get regionalized group velocity for each block of the research area. Then, surface wave inversion method was applied to invert the shear wave velocity of the each block from regionalized the group velocity. Finally, the shear wave velocity structure of each block is combined to form the three dimensional shear wave velocity structure of the crust under the Taiwan region. The result shows the velocity structure of Taiwan area has significant lateral heterogeneity. The velocity structure shows exist horizontal velocity discontinuity about 10 km and 20 km. Velocity discontinuity has a trend of eastward thickness.
