Table 1 Q _P and V _P structure beneath Kumano Basin

From: Q _P structure of the accretionary wedge in the Kumano Basin, Nankai Trough, Japan, revealed by long-offset walk-away VSP

Layer	Depth (km) ^a	Q _P ^−1b	Q _P	Q _{P, min} ^c	Q _{P, max} ^c	V _P (km/s)
L1	2.06 to 2.7	0.029 (4.5e⁻³)	34	30	41	1.7 to 2.0
L2	2.7 to 4.1	0.018 (1.2e⁻³)	57	53	61	2.2 to 2.7
L3	4.1 to 10.8	0.029 (2.2e⁻³)	349	198	1,500	3.6 to 4.6

^aMeasured from sea surface at site C0009; ^bestimation errors are given in parentheses; ^clower and upper limit of Q _P are from the estimation errors of Q _P ⁻¹.
