From: Shallow structure and late quaternary slip rate of the Osaka Bay fault, western Japan
Seismic profile Line 1 (Boomer). TWT: two-way travel time. Vertical line represents location of cross lines. (a) Uninterpreted image (post-stack, vertical exaggeration = 20). Red triangle: representative seafloor multiple. (b) Trace of seismic reflectors in (a) and interpreted image. Star shows location of sediment thickness measurement in Fig. 24. Unit A1 exhibits chaotic internal structure with a wavy and irregular base, indicating an erosional contact (CMP #3000–3800). Continuous tilting of strata by the hanging wall anticline of the Osaka Bay Fault is observed to reach to shallow depths
