(a) The initial model for checkerboard resolution test of group velocity. Recovered results for the periods of (b) 8 and (c) 16 s. Stations and active faults depicted by black triangles and lines, respectively. The black thick solid border separates area with insufficient lateral resolution. The background velocities are 2.65 and 2.98 km/s for 8 and 16 s, respectively.
