Locations of the NanTroSEIZE drilling sites (a, b) and Distribution of vitrinite reflectance overlaid on photographs of slab core samples (c). (a) Regional tectonic setting of the IODP NanTroSEIZE drilling transect and rupture of the 1944 Tonankai earthquake (after Moore et al. 2007 and Kikuchi et al. 2003). Black line shows the location of the cross-section in (b). Abbreviations in inset: PP, Pacific Plate; PSP, Philippine Sea Plate; EP, Eurasian Plate; NAP, North American Plate. (b) Seismic profile along the NanTroSEIZE drilling transect (after Moore et al. 2007). VE, vertical exaggeration. (c) Photographs of the core sample that intersects the megasplay fault at Site C0004 (left) and of the frontal décollement (right) (after Sakaguchi et al. 2011). Black dots on the photographs indicate vitrinite particles measured by Sakaguchi et al. (2011) and color indicates Ro, reflectance of vitrinite. White dotted line indicates the location of a slip zone.
