Compressional and shear wave velocities were examined for sediments from the hanging wall and footwall of the megasplay fault in the Nankai accretionary prism, obtained during Integrated Ocean Drilling Program (IODP), Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) Stage 1. The samples were cored at Expedition 315 Site C0002 and Expedition 316 Site C0004. Three samples were tested from each site. At Site C0002, one sample is from forearc basin sediments and two samples are from accreted sediments. At Site C0004, one sample is from slope-apron sediments and two samples are from underthrust sediments in the footwall of the megasplay fault. Laboratory tests were conducted with controlled pore fluid pressure. Compressional wave velocity covered a range from approximately 2010 to 2370 m/s at Site C0002 and approximately 1790 to 2200 m/s at Site C0004, both under hydrostatic fluid pressure conditions. Shear wave velocity ranged from approximately 720 to 950 m/s at Site C0002 and approximately 650 to 940 m/s at Site C0004. VP/VS ranged from approximately 2.5 to 2.8 at Site C0002 and approximately 2.3 to 2.7 at Site C0004, with a mean of approximately 2.6. Computed shear modulus ranged from approximately 1.0 to 1.88 GPa for Site C0002 and approximately 0.79 to 1.76 GPa at Site C0004. Bulk modulus ranged from approximately 6.60 to 9.24 GPa at Site C0002 and from approximately 4.22 to approximately 7.17 GPa at Site C0004.
