Previous studies indicate that the present-day tectonic and depositional settings of the study area started at ~ 2.2 Ma in a frontal wedge-toe position (Strasser et al., 2009). Splay fault movement was initiated at ~ 1.95 Ma in the lower part of the accretionary wedge. Ongoing megasplay slip occurred since ~ 1.55 Ma (Strasser et al., 2009). Towards its eastern part displacement ceased at ~ 1.24 Ma, suggesting that it only experienced a relatively short Cyclin dependent kinase inhibitor 2A of high activity between ~ 1.55 and 1.24 Ma. In addition, Gulick et al. (2010) recognised a major phase of landward tilting in the Kumano Basin, landward of the MSF, and inferred activity of the MSF system between 1.3 and 1.0 Ma. This phase postdates an earlier phase of asymmetric forearc-high uplift, with strongest uplift in the southwestern part of the Kumano transect occurring together with splay fault steepening and underthrusting of large volumes of sediment (Bangs et al., 2009).
