Fig. 2From: New hypothesis to explain Quaternary forearc deformation and the variety of plate boundary earthquakes along the Suruga–Nankai Trough by oblique subduction of undulations on the Philippine Sea PlateOffshore geologic structure and marine terrace height in Shikoku and the Kii mountains. Offshore geologic structures south of Shikoku (within the dashed line) are simplified from Okamura (1990). Heights of the MIS 5e marine terrace are from Koike and Machida (2001). Locations of emergent fossil assemblages are from Maemoku (2001) and Shishikura et al. (2008)Back to article page
