Fig. 4From: Configuration and structure of the Philippine Sea Plate off Boso, Japan: constraints on the shallow subduction kinematics, seismicity, and slow slip eventsConfiguration of the grid nodes during the tomographic inversions and the projected lines for the stacked RF images. The crosses represent the locations of velocity nodes in the horizontal section. The triangles and squares indicate stations. Lines A–A′, B–B′, C–C′, D–D′, and E–E′ define the locations of the depth-domain RFsBack to article page
