Fig. 7From: Deep subduction of the Philippine Sea slab and formation of slab window beneath central JapanIso-depth contour map of the PHS slab geometry model obtained in this study. Red contours are from the existing PHS slab model. Green contours represent the upper surface of the PHS slab that has been estimated in this study. The area within the dashed blue line is the area where the PHS slab does not exist (i.e., slab window). The black triangles indicate volcanoesBack to article page
