From: Detailed bathymetry and magnetic anomaly in the Central Ryukyu Arc, Japan: implications for a westward shift of the volcanic front after approximately 2.1 Ma

Figure 5

Schematic models for the westward shift of the volcanic front in the Central Ryukyu Arc. Shallowing of slab depth and dip angle caused by (a) termination of asthenospheric upwelling and (b) rapid trench retreat due to the change in subduction direction of the Philippine Sea Plate at approximately 2 Ma. The scales of vertical, horizontal, and slab dip angles are arbitrary.
