Fig. 5From: Investigating P- and S-wave velocity structure beneath the Marmara region (Turkey) and the surrounding area from local earthquake tomographyReconstructions of three checkerboard tests with anomaly spacing of 20, 30, and 50 km. The shallower section is at 5 km depth, and the deeper sections are at different depths corresponding to the deepest level where the recovery is satisfactory. Shapes of anomalies are indicated with thin line contours. Triangles depict seismic stationsBack to article page
