left: Map showing the Nankai Trough area (modified from Screaton et al. 2009 and Hammerschmidt et al., 2014). Subduction of the Philippine Sea plate occurs at a rate of 4.1 to 6.5 cm/yr. Site C0002 is situated at the southern rim of the Kumano forearc basin, which is located between the Muroto Basin in the southwest and the Enshu Trough in the northeast. The regional tectonic setting is displayed in the inset (EP= Eurasian Plate, NAP = North American Plate, PP= Pacific Plate, PSP = Pacific Sea Plate).
